I recently repaired a switch’s controller rail that the customers kid ripped off. After the repair (Next day)she comes back with it ripped it off again. Said I did a Shoddy job, which I did not. Through interrogation tactics, she admitted that her kid was jumping on the bed with the switch and ripped it off again. Figured so. 🤦🤷
I used todo a lot of virus removal on peoples computers. The bulk of them were from people going to dodgy porn sites. This was back in 2010. One person came back with a computer the next day saying that I did not get rid of the virus. I checked browser history and time stamps on virus files and they took the computer home and went back to the dodgy website as soon as they went home trying to find what ever sick sh*t they were looking for last time .
Working in IT myself. i've heard customers complaining about their printer stopped working after a tech fixed a microsoft outlook email issue on their computer, saying "it was working before you touched it!" customers can be very stupid and aggravating
I always have the highest respect for people who can solder on tiny things like that MOSFET.. My soldering skills have never been that great, and I cetainly dont have stable enough hands to do it now. Well done.
Usually when I visit repair shops I can sometimes see how tired their eyes are. I guess, from your perspective, it's the constant interactions with obnoxious customers or just dealing with relatively more people in general.
They only mail the motherboard because the package will be lighter -> Less shipping costs. However, they usually don't think twice about that no testing means less chance of it actually working which in turn would mean another repair attempt -> More money wasted.
There is a 50% chance that the CPU is also dead on this one. Especially with Alienware which has strong 19V power supply that would spike the CPU nicely with full power and then go into overload.
Customers are sometimes strange. About 4 years ago I repaired a 17-inch Asus laptop where the power button was broken. The customer has now complained that the fault has reoccurred, the button is broken again. He sent a copy of the invoice and asked for rectification. Then he sent me a tablet with a discharged battery....
@@terasestHammasratas Yes, I repaired an Asus F75 at the power button and 4 years later got an Asus T101H with a dead battery (after charging it worked) from the customer and he wanted to have it repaired under warranty.
@@SiETechNotebookReparatur I often get customers that bring stuff that was supposedly serviced by us before, while there is absolutely no entry in our database but they are sooo convinced about it, usually, it turns out that either they serviced it somewhere other place or had a totally different computer repaired with us.

Very interesting video.

Hello Alex, where do you get all these different MOSFETs from? I struggle to purchase them takes weeks to get. Do you have books for them like the capacitors and resistors?
I do board repair at my own job (luckily, not for end users and no one is trying to accuse me of doing the damage) and I have improved so much and so quickly thanks to your videos. Thank you!
I just got a laptop from a customer to install an external capture card. Customer didn't bother to tell me the Windows password. Obviously I will return the laptop to the customer saying that I really am not able to install anything on his laptop because I am really stupid. I know that the client will never come to me for a repair but this is a huge win for me, every time.
It is a shame Alienware laptops can be nightmares with really odd failures that their business class machines very rarely experience then there is the parts issue especially for the older models like the M18x R2 for example.
Could it be that the reason business class machines very rarely experience those failures compared to the gaming machines is because they spend their lives loitering and aren't pushed to the limits creating a lot of excess heat?
I believe that OEMs haven't designed the heat management systems in these 'gaming laptops'. Why are we having all of these failures, if they did? Or maybe it's people using that high-powered heat bomb in the laps or on the bed? I don't know, but it just seems weird to me, that this isn't recallable. How many companies machines does Alex fix? All of them that make these machines, that's how many. Practically industry-wide to me, but correct me if I'm wrong. Helps to re-align my thinking. 👍
When you invoice your customer and ship the repaired device to them, do you also have a brief description of the parts that were used as well as the procedures performed for the repair?
I feel your pain. People get the craziest ideas. MY #1 was a older German woman saying her printer got infected with a virus from her computer (this was 2002), the virus was our fault.
Those were the good old days where people got confused by the word virus. They would clean the computer and the rooms that they set computers were cleaned and dust free. 😁 Now, it's a mini treasure hunt when you open a customer's desktop PCs. Pens, old 2gb pendrives, old unpacked candies, broken SD cards, spiders, dead lizards, roaches etc.
Years ago a guy brought me a DELL to replace battery; it just unsnaps and drops out the bottom. I install new, OE battery, but laptop dead. Customer claim it worked before we change battery. It got ugly.
in this video you ask how to detect short when mosfets are still attached. this seems very challenging but perhaps with a precision instrument like a very sensitive multimeter? is that possible? for example if you started by removing 2 of the mosfet in the middle. then the remaining ones at either end of the line will be further away from each other. which can increase slightly the resistance from one end of the pcb to the other end. but you might need a pretty expensive multimeter (and for a lower power device with less heavy thick pcb traces) but another more sophisticated method would be to use an electric field meter. to detect where the current flow on the pcb was higher. this would occur near to the location of the shorted path. so long as you can flow enough current to be able to detect the presence of a strong enough electric field. again - i am not sure if the equipment can be sensitive enough to detect in these situations. it is challenging
hi alex great job on the mosfets great observation ... i know its a pain in the backside but maybe you consider making a video of inspection of any device before and after each repair to counter act any stupid individuals trying to scam you and your business... blacklist the individual .....
I'm always excited when i get a notification about a new video from you. Love your way of analyzing, soldering and your humor. Keep up the great content
It appears as though CPU mosftet 2 was replaced with the exact same damaged mosfet on the first attempt. It had the same markings if you rewind the video and compare.
Hey you still can test only the motherboard maybe hdmi/vga cable. Back in the days I bought a good laptop board for cheap then used it as a PC in a cardboard custom case and custom cooling and it worked great
When I was a mechanic we called that "sinceyou" disease. "since you worked on this, now this is broke". We had one guy whos truck needed a transmission replaced which we did. he came back a week later saying "since you changed my transmission, my back door handle doesn't work any more. you guys broke it while changing the transmission and need to replace it!".
Always take photos of pre-work start, and if someone is turning something in directly. Always inspect and point noticeable damage. Have the customer accept the pre-existing damage before accepting turn in.
@@supupandaway8138 obviously…. Thanks captain obvious… google doesn’t always find everything I’d hope you know … I buy parts all the time you’d NEVER find in a “search”
Sometimes the part numbers are written differently in the schematics, sometimes you can find different ordering part numbers in the actual datasheet. Mostly donor boards though.
I'd love to hear back from the customer if that fixed it. I mean, I am sure it did ... but it would still be nice to know. I wonder why they sent the board only ... maybe they were scared that you would steal/view their HD or something
@@Siminfrance Really shouldn't, it's mainly dependent on size until you get very heavy. The full laptop isn't much bigger than just the motherboard. That said a USPS flat rate box negates that. *shrug*
Its not the shipping they had it apart already figured it was the motherboard and knew they would save on disassembly labor so they sent just the board
@@TLM-Nathan Didn't fit in any USPS flat rate box. Also didn't feel like reassembling entire laptop when under the impression that repair shop only needed motherboard.
Dealing with that iPad customer is the reason why I don't do repair for people. I once helped my friend's mom with her computer by replacing her CD-ROM drive. She then called me every time her cable modem went out and blamed the issue on me for fixing the CD-ROM. In her eyes, all computer issues are lumped together even though the issues are completely unrelated. I don't have the patience for it and there are some people who will never understand.
I worked at a call center that had the Raytheon contract. I had one person want to know what their new laptop will way. We're not the ordering dept. We don't know. I had to find out her current and new laptop weights. That was 1o minutes of my life I never got back.
Yeah some customers say pretty stupid stuff when they know they are gonna loose some money again because of accident or miss handling. Bending of the housing indeed has nothing to do with the glass. We had a customer who constantly broke USB-C port of a Lenovo M10 tablet and she continued to claim that the tablet was bad and after 2 warranty claims and 2 times we our selves swapped the USB-C port, she wanted her money back when the port broke 5th time. Of course we didn't agree because we now have a broken device and we have serviced it basically for free besides the warranty claims which the manufacturer replaces necessary parts. We have sold quite a few of these tablets and rarely had issues and most certainly not the same issue multiple times with the same device. When it comes down to USB-C you rarely see the port being bad quality, instead it is most of the ripped from the bad quality PCB. If you see ports where the housing is starting to spread open that's when you know customers has yanked the cable sideways or forced it in from an angle. She is not our customer anymore not due to us selling (in her mind) bad products but because of "bad customer service". I have heard similar stories when someone bought a car and had clutch issues and of course there was no possible way for him/her to be the problem :D
If you get a hot CPU when voltage injection, can it ever be another shorted component sending current to CPU and to ground making it seem like the CPU is shorted? Thanks. Love your videos. Best on youtube
That's actually exactly what happened in this video. But the component is not what is sending the current. Since the component is shorted, the current is just passing right through it, and it's not "checked." If you're familiar with coding or even using Excel, the purpose of MOSFETs are to act as an IF statement.
@@TheResoluteHawk That's not what he asked. To answer the question - yes. If for instance there is part of logic that got messed up badly (usually from liquid damage), the IO controller often gets the whole shaft (South Bridge) and will get the internal silicon structure shorted out, I see this often. You may not have a short on the main power rail, but it might bring down accessory rails like 3.3V, very common. Usually, I deem those as no fix and replace the board. Not worth the cost and effort to replace the BGA CPU.
Why do you always get weird customers man like.. Fuck... you provide such a quality service with extra steps and extra diagnosis, everything the whole shabang and people still find a way to try and make you look bad it baffles me. Keep up your good work
@@ernestmccollum2397 I know but especially when this guy has a solid community around him, VODs of everything he does, clearly documents every single tiny piece of evidence and detail like the customer in this scenario is fighting a losing battle and only embarrassing themselves. This guy would own up if he ever made a mistake or messed up and no doubt he would then rectify that mistake. But you are right they will always exist
@@Tegridy_Gaming I don't think any of what you said matters to a customer that doesn't have any idea about this youtube channel. I think for most people watching here there is a general understanding of electronics repair at the least. Most customers of an electronics repair shop will have little to no idea what is involved in a repair. If someone believes that a screen repair can turn a metal case "soft" you better believe they have little to no idea. The customer may have been obviously wrong to this audience but I bet you could find large groups of people that would believe softening metal could be possible. If you have no idea what solder is and then the first thing you learn about electronics repair is that metal is melted to fix broken stuff then it isn't a huge leap to getting it arse backwards and believing people have weakened your case by doing a repair. A little knowledge is a dangerous thing!
Even the short is gone there the CPU is dead.... i had 17R4 all with the same issue. After u had few of them in your shop, you know what i am telling ;)
So, if i have a board that while voltage injection CPU getting hot but no other component, how can i find the faulty component? how can i know if it is not the CPU itself ?
I was laughing to myself about that iPad. Totally unrelated but I've fixed boilers for people and then they've rang me because their garden tap has "only started dripping" since I fixed their boiler. Or the lightbulb has blown in the bedroom, or etc etc etc. 😂 "The job would be ok without customers"
You should have a policy, when they pick up the product they need to inspect an sign that they get a product in good condition and all complains after that is useles.
Nice work investigating. with the iPad customer, tell them to report the soft metal problem to Apple, after all, it's their design that needs to be fixed. ;)
Since you repaired my tablet, my car won't start, my garage door won't open, my toaster oven burns everything, my wife left me, my kids won't talk to me, my bank account is overdrawn, and I've developed a severe case of halitosis. I guess I spent all that money for nothing. Good job not making the metal soft, though.
Is it safe to say that most of these laptops die due to thermal issues? Seems like they sacrifice cooling performance so they can reduce weight and laptop size. Have you ever seen a mosfet fail on a regular PC motherboard when they have a huge heat sink on them and airflow from fans? I haven't. Especially modern motherboard ones they usually top out around 65-75C under max load because they are better cooled and there's a lot more of them so the load is more evenly spread.
From my experience: All laptops that died on me, died due to overheating. So yes. Cooling is probably the main issue. While laptops nowadays achieve quite good cooling on GPU und CPU, there's little to no airflow inside the case and every other component overheats on longer sessions. Especially when gaming. After killing my 3rd laptop with a dedicated GPU while doing heavy work on it, I settled for a laptop with an iGPU. Has been going strong for 5 years now. People think I look out for lower TDP because of battery life, but for me it's now gotten kind of a precaution, because lower tdp = lower heat... I won't buy a high tdp laptop ever again, due to cooling.
Yup, thermal cycling is the number 1 killer, especially in the "gaming" category. They get crap in the cooling system quicker as they eat through vast amounts of air compared to more typical laptops.
Hi i run a repair shop in tunisia and i have a question i hope you answer i noticed you never call the costumer after you diagnose the device to tell the price or do you charge the same amount of money for every repair?
Hello from France ! I found your channel one month ago. I learn a lot of things thanks to you, . I am now subscribed. Keep it up Alex ! Too bad France is so far away to send some cards.
Its always MOSFETs! Is there something about them that causes them to fail all the time? Or is it just that they are typically in the power circuits and so are potentially susceptible to damage more?
MOSFETs are often used as switch or amplifier, so you will see them carry lot of current. Often you'll see heat sinks attached to them if they work as amplifier. So, lot of energy goes through them with lot of current cycles that lead to wear and eventual failures. Having said that, good mosfets can last very long time.
When you put your hands on your head I know exactly how you felt I had a customer bring a Nintendo switch in for screen replacement I did the screen replacement and they come back a week later saying it stopped working I opened it up and it was drowned in some sort of liquid I wanted to bang my head against a wall 😂😭

Man I love customers. Someone took a ps5 hdmi repair. The very next day, he came back saying the hdmi didn't work. His son ended up breaking it the day they got it back. Man
What the neck is with all the people destroying HDMI ports? I've got a lot of gear with HDMI but never damaged even one of them. Are they throwing the gadgets around by the cords or what? People make no sense.
@@LatitudeSky sometimes, they try to shove it into a place with cable plugged in, or drop it while they try to move it while it is on and connected, or simply try to forcefully plug the hdmi connector upside down
Customers represent a random cross-section of humanity. And by definition, half of humanity (exactly) has below-average common sense. Unfortunately, that’s kind of what you sign up for if you’re in customer service. God bless Alex because I could not tolerate the people that he does.
I sold a ps5 to someone and he harassed me with calls the rest of the day saying the ps5 had issues, the ps5 was "acting strangely", and wanted a refund. After hours of back and forth he told me the problem. His card information was getting declined by the Amazon app............................. My brother in Christ..... I told him to try a different card and he sheepishly replied later "I fixed it".
Love watching your videos before sleep, your clean voice with consistent wording, the white noise of the hot air station, the occasional beeps of the meter, the moments of happiness where an issue appears to be fixed. It's enough noise for me to feel safe and fall asleep calmly.

@@apps2rescu Yes, it's a shit show. People just don't care and only act when the shit breaks. The smelly stuff is the worst.
@@FrozenHaxor exactly. The laptops' keyboards are the most awful sights to see in front of us.
Admire your work sir. My graduate classes go well because of your videos and information and techniques. Love from India. ❤️
Started bing watching the channel. almost done with all the videos
That metal housing was obviously your fault 100%. You replaced the metal housing with low melt solder 😂
😂😂 Low melt solder..must be
in this video you ask how to detect short when mosfets are still attached. this seems very challenging but perhaps with a precision instrument like a very sensitive multimeter? is that possible? for example if you started by removing 2 of the mosfet in the middle. then the remaining ones at either end of the line will be further away from each other. which can increase slightly the resistance from one end of the pcb to the other end. but you might need a pretty expensive multimeter (and for a lower power device with less heavy thick pcb traces)
but another more sophisticated method would be to use an electric field meter. to detect where the current flow on the pcb was higher. this would occur near to the location of the shorted path. so long as you can flow enough current to be able to detect the presence of a strong enough electric field. again - i am not sure if the equipment can be sensitive enough to detect in these situations. it is challenging
hi alex great job on the mosfets great observation ... i know its a pain in the backside but maybe you consider making a video of inspection of any device before and after each repair to counter act any stupid individuals trying to scam you and your business... blacklist the individual .....
I'm always excited when i get a notification about a new video from you. Love your way of analyzing, soldering and your humor. Keep up the great content
Definitely worth a subscribe. This is excellent content.
It appears as though CPU mosftet 2 was replaced with the exact same damaged mosfet on the first attempt. It had the same markings if you rewind the video and compare.
Hey you still can test only the motherboard maybe hdmi/vga cable. Back in the days I bought a good laptop board for cheap then used it as a PC in a cardboard custom case and custom cooling and it worked great
I love the way you work, excellent videos
When I was a mechanic we called that "sinceyou" disease. "since you worked on this, now this is broke". We had one guy whos truck needed a transmission replaced which we did. he came back a week later saying "since you changed my transmission, my back door handle doesn't work any more. you guys broke it while changing the transmission and need to replace it!".
Always take photos of pre-work start, and if someone is turning something in directly. Always inspect and point noticeable damage. Have the customer accept the pre-existing damage before accepting turn in.
Maratoning your videos! Very spiring!
That looked pretty easy lol.
How did you find a replacement mosfet
Looking up the part number or a parts board
@@supupandaway8138 obviously…. Thanks captain obvious… google doesn’t always find everything I’d hope you know … I buy parts all the time you’d NEVER find in a “search”
Sometimes the part numbers are written differently in the schematics, sometimes you can find different ordering part numbers in the actual datasheet. Mostly donor boards though.
I'd love to hear back from the customer if that fixed it.
I mean, I am sure it did ... but it would still be nice to know.
I wonder why they sent the board only ... maybe they were scared that you would steal/view their HD or something
@@mikeuk666 really, I didn't think it would make such a difference.
But I guess it is possible.
@@Siminfrance Really shouldn't, it's mainly dependent on size until you get very heavy. The full laptop isn't much bigger than just the motherboard. That said a USPS flat rate box negates that. *shrug*
Its not the shipping they had it apart already figured it was the motherboard and knew they would save on disassembly labor so they sent just the board
Probably trying to cut cost on shipping and thought would be less labour if they didn’t have to take the board out when repairing it
@@TLM-Nathan Didn't fit in any USPS flat rate box. Also didn't feel like reassembling entire laptop when under the impression that repair shop only needed motherboard.
I think you need to look up Uri Geller. I think he has been teaching you some skills.
Ahhh, RIP James Randi, so many memories.
Top work as always. Just goes to show the customer is NOT always right!
Dealing with that iPad customer is the reason why I don't do repair for people. I once helped my friend's mom with her computer by replacing her CD-ROM drive. She then called me every time her cable modem went out and blamed the issue on me for fixing the CD-ROM. In her eyes, all computer issues are lumped together even though the issues are completely unrelated. I don't have the patience for it and there are some people who will never understand.
I worked at a call center that had the Raytheon contract. I had one person want to know what their new laptop will way. We're not the ordering dept. We don't know. I had to find out her current and new laptop weights. That was 1o minutes of my life I never got back.
@@gerrymichaud3851 lmao thats the worst it got for you? Hard life
@@boppernostopper8598 No not the worse, but weird
Yeah some customers say pretty stupid stuff when they know they are gonna loose some money again because of accident or miss handling.
Bending of the housing indeed has nothing to do with the glass.
We had a customer who constantly broke USB-C port of a Lenovo M10 tablet and she continued to claim that the tablet was bad and after 2 warranty claims and 2 times we our selves swapped the USB-C port, she wanted her money back when the port broke 5th time.
Of course we didn't agree because we now have a broken device and we have serviced it basically for free besides the warranty claims which the manufacturer replaces necessary parts.
We have sold quite a few of these tablets and rarely had issues and most certainly not the same issue multiple times with the same device.
When it comes down to USB-C you rarely see the port being bad quality, instead it is most of the ripped from the bad quality PCB.
If you see ports where the housing is starting to spread open that's when you know customers has yanked the cable sideways or forced it in from an angle.
She is not our customer anymore not due to us selling (in her mind) bad products but because of "bad customer service".
I have heard similar stories when someone bought a car and had clutch issues and of course there was no possible way for him/her to be the problem :D
so much patience, god
If you get a hot CPU when voltage injection, can it ever be another shorted component sending current to CPU and to ground making it seem like the CPU is shorted? Thanks. Love your videos. Best on youtube
That's actually exactly what happened in this video. But the component is not what is sending the current.
Since the component is shorted, the current is just passing right through it, and it's not "checked."
If you're familiar with coding or even using Excel, the purpose of MOSFETs are to act as an IF statement.
@@TheResoluteHawk That's not what he asked. To answer the question - yes. If for instance there is part of logic that got messed up badly (usually from liquid damage), the IO controller often gets the whole shaft (South Bridge) and will get the internal silicon structure shorted out, I see this often. You may not have a short on the main power rail, but it might bring down accessory rails like 3.3V, very common. Usually, I deem those as no fix and replace the board. Not worth the cost and effort to replace the BGA CPU.
Nice work again!
And I quote : " How can we make metal soft, I wish I had that power" Dude, we watch you make metal soft every episode. You obviously ripped her off /s
Are there different types of MOSFET, or it's only 1 specific component?
Why do you always get weird customers man like.. Fuck... you provide such a quality service with extra steps and extra diagnosis, everything the whole shabang and people still find a way to try and make you look bad it baffles me. Keep up your good work
Customers like that will always be around.
@@ernestmccollum2397 I know but especially when this guy has a solid community around him, VODs of everything he does, clearly documents every single tiny piece of evidence and detail like the customer in this scenario is fighting a losing battle and only embarrassing themselves. This guy would own up if he ever made a mistake or messed up and no doubt he would then rectify that mistake.
But you are right they will always exist
Many stupid people out there...
man you softened my brain
@@Tegridy_Gaming I don't think any of what you said matters to a customer that doesn't have any idea about this youtube channel. I think for most people watching here there is a general understanding of electronics repair at the least. Most customers of an electronics repair shop will have little to no idea what is involved in a repair.
If someone believes that a screen repair can turn a metal case "soft" you better believe they have little to no idea. The customer may have been obviously wrong to this audience but I bet you could find large groups of people that would believe softening metal could be possible. If you have no idea what solder is and then the first thing you learn about electronics repair is that metal is melted to fix broken stuff then it isn't a huge leap to getting it arse backwards and believing people have weakened your case by doing a repair.
A little knowledge is a dangerous thing!
Even the short is gone there the CPU is dead.... i had 17R4 all with the same issue. After u had few of them in your shop, you know what i am telling ;)
So, if i have a board that while voltage injection CPU getting hot but no other component, how can i find the faulty component? how can i know if it is not the CPU itself ?
With this video I learn something new today 😉
I was laughing to myself about that iPad. Totally unrelated but I've fixed boilers for people and then they've rang me because their garden tap has "only started dripping" since I fixed their boiler. Or the lightbulb has blown in the bedroom, or etc etc etc. 😂
"The job would be ok without customers"
الله معك يا اخي. Same problem with customers in every part of the world 😂😂
You should have a policy, when they pick up the product they need to inspect an sign that they get a product in good condition and all complains after that is useles.
sir these new mosfers are not same so the build number is not important?
since you fixed my laptop now my fridge freezer doesn't work lol
what would have most likely caused both mosfets to fail?
Good day, I want to start a Repair Channel like this, but a lot of things discouraging me
Nice work investigating. with the iPad customer, tell them to report the soft metal problem to Apple, after all, it's their design that needs to be fixed. ;)
Since you repaired my tablet, my car won't start, my garage door won't open, my toaster oven burns everything, my wife left me, my kids won't talk to me, my bank account is overdrawn, and I've developed a severe case of halitosis. I guess I spent all that money for nothing. Good job not making the metal soft, though.
Im not a scientist, so i would like to know why you didn't wick old solder off and apply new solder?
good job mate.
Hi from Greece, how you record at 60 fps with microscope camera? Is the camera supporting it or you use something external ?
Thanks in advance!
It has 60 frames per second through the HDMI output, and his capture card supports that frequency.
I KNEW you secretly were Magneto in disguise! You just do all this soldering to keep your true identity a secret! :D
Is it safe to say that most of these laptops die due to thermal issues? Seems like they sacrifice cooling performance so they can reduce weight and laptop size. Have you ever seen a mosfet fail on a regular PC motherboard when they have a huge heat sink on them and airflow from fans? I haven't. Especially modern motherboard ones they usually top out around 65-75C under max load because they are better cooled and there's a lot more of them so the load is more evenly spread.
The problem is even more complex, customers want quiet appliances, so cooling is often poor, but quiet.
From my experience: All laptops that died on me, died due to overheating. So yes. Cooling is probably the main issue. While laptops nowadays achieve quite good cooling on GPU und CPU, there's little to no airflow inside the case and every other component overheats on longer sessions. Especially when gaming. After killing my 3rd laptop with a dedicated GPU while doing heavy work on it, I settled for a laptop with an iGPU. Has been going strong for 5 years now.
People think I look out for lower TDP because of battery life, but for me it's now gotten kind of a precaution, because lower tdp = lower heat... I won't buy a high tdp laptop ever again, due to cooling.
Yup, thermal cycling is the number 1 killer, especially in the "gaming" category. They get crap in the cooling system quicker as they eat through vast amounts of air compared to more typical laptops.
You know YOU stepped on that ladies I pad! lol
Hi i run a repair shop in tunisia and i have a question i hope you answer i noticed you never call the costumer after you diagnose the device to tell the price or do you charge the same amount of money for every repair?
Accidents happens but insurance is clammed 😂😂😂😂🤣
I'm very curious to ask you what kind of metal softener you are using...!!!
we can supply touch screen and lcd screen for your broken touch
انت برنس🤝
I like your work
I like your english
How did you know that the drain was shorted, drains sometimes are connected to ground
not the first two mosfet after dc ....you mean the lower n mosfet in buck converter circuit like two mosfets and coil
Hello from France ! I found your channel one month ago. I learn a lot of things thanks to you, . I am now subscribed. Keep it up Alex ! Too bad France is so far away to send some cards.
Its always MOSFETs! Is there something about them that causes them to fail all the time? Or is it just that they are typically in the power circuits and so are potentially susceptible to damage more?
MOSFETs are often used as switch or amplifier, so you will see them carry lot of current. Often you'll see heat sinks attached to them if they work as amplifier. So, lot of energy goes through them with lot of current cycles that lead to wear and eventual failures. Having said that, good mosfets can last very long time.
They are a switch from positive to negative they don’t play nice together most of all when you start adding heat
Customers will be Customers
I feel so sorry for you having to deal with stupid people.
When you put your hands on your head I know exactly how you felt I had a customer bring a Nintendo switch in for screen replacement I did the screen replacement and they come back a week later saying it stopped working I opened it up and it was drowned in some sort of liquid I wanted to bang my head against a wall 😂😭
Hello, I have a short in my Alienware as well and I was wondering where was the other probe for the buzzer was located since I can't see it in the video.
Thank You xD
On the ground of the laptop, either a copper screw hole, USB, HDMI, VGA metal housing or battery black wire (battery unplugged)
@@andchip.s Thank You very much!, also.. The laptop doesn't need to be powered by battery nor power brick right?
@@jasonfang5880 That's correct, no power needed, if you are just looking for a short circuit.
Why dont you test the mosfet after desoldering them?
Man I love customers. Someone took a ps5 hdmi repair. The very next day, he came back saying the hdmi didn't work. His son ended up breaking it the day they got it back. Man
What the neck is with all the people destroying HDMI ports? I've got a lot of gear with HDMI but never damaged even one of them. Are they throwing the gadgets around by the cords or what? People make no sense.
@@LatitudeSky sometimes, they try to shove it into a place with cable plugged in, or drop it while they try to move it while it is on and connected, or simply try to forcefully plug the hdmi connector upside down
Customers represent a random cross-section of humanity. And by definition, half of humanity (exactly) has below-average common sense. Unfortunately, that’s kind of what you sign up for if you’re in customer service. God bless Alex because I could not tolerate the people that he does.
I sold a ps5 to someone and he harassed me with calls the rest of the day saying the ps5 had issues, the ps5 was "acting strangely", and wanted a refund. After hours of back and forth he told me the problem. His card information was getting declined by the Amazon app............................. My brother in Christ..... I told him to try a different card and he sheepishly replied later "I fixed it".
In Re; the back housing got weak... that is exactly why I quit working on car's as a favor from home!
^..^~~
Good job thanks for the video.
