Your viewers got me here before I had a chance to watch the video. Zephyrus laptops are Indeed. tricky and not always fixable. Zephyrus models are famous for having CPU and Ram issues. Vram / GPU could also be at fault. Sometimes the culprit is never found considering no boardview diagrams are available for this model. Shorts can just spiderweb and appear in many areas as you have shown. Knowing when to stop is something I used to struggle with but i learned to call it a no fix when I do not see light at the end of tunnel. I'll be happy to take a look at it assuming you still have the laptop and you want to do that.
Hi, I have a question about the problem like in the movie. If we find an element causing a short and desolder it, can we repeat the short - circuit test (giving voltage on a specified line) without soldering a new element in the missing place? I mean, can the missing element cause us to damage other elements during a short - circuit test?
This seems to be the result of bricking the laptop after plugging in the USB-C power along side the DC power chord. This model had that issue for many owners on the 2020 model. It was fixed on the 2021 model
A little too late to save this laptop, but here's one thing I noticed: The component that got hot at 8:36 most likely wasn't the chip but rather the large silver component to the right of it (marked D5907). This is a PTC polyfuse, which is a type of fuse that resets itself automatically once the fault is cleared. It works by getting very hot when too much current passes through it, and when it's hot, its resistance rises dramatically (thereby limiting the fault current). Since it got hot, that meant that there was a short after that fuse. (Once the polyfuse cools down, its resistance becomes low again.) No idea if you'll read this, but keep up the great videos!
Here is some tip to figure out which component exactly is overheating: you need thermal paper that is usually used in cash register (just save one that they give you when you go to grocery store) and then put it with clean side on the heated area. The exact component will leave a black spot on the paper, just lift it that way that you will be able to figure out which one it was
Yes! Those papers are also used in POSs and just have a layer of invisible ink that shows up when introduced to heat eliminating the need to refill your register or atm or pos with ink.
Needs to be much hotter to leave a mark. If he aligned the Flir camera a bit better it would be easier to find the component, other common method is to pour isopropyl alcohol on it and you will see and hear it sizzle and evaporate quickly.
the resistors with 0's on them are just zero ohm links - so the fact that they are both shorted doesn't mean it is a fault unless it isn;t meant to be a ground trace
I would never say that as a repairman, you should never put people down like that completely. You don't know more of the context, for all we know with the right guidance he could be better than even our guy right here.
@@jiehfeng I 100% agree with you, as an amateur when I first tried to repair I actually made it worse but with time, knowledge and training it gets better and better
Reminds me of a repair I had to do where the 5V rail was shorted to ground, but I didn't have a good way of isolating it down to a single component. I ended up saying screw it and removed ~18 caps and another ~18 DIPs. Got rid of the short by replacing all of the components. Wish I would have thought about injecting a current into the circuit and watching where it heated up. Would have saved me a lot of time and soldering. 😅
@@Tronicsfix Hmm, is there any physical damage to the board? Maybe when the guy was taking it apart there was some flex that somehow bridged two traces between layers? Sort of like what happened with that one Xbox One where they used a long screw by accident and punctured part of the board.
I have seen similar situations in the past. It can happen when 3.3v rail gets 20v by accident and in such case nierly all components on 3.3 gets zapped and shorted. I'm not saying you have such case. I'm just speculating that if wrong voltage gets into particular rail by fat fingers or screws driver etc. It can short so many components. Ect.
It's kind of like a more complex Lego technic set , pieces that does something specific , in combination with others they do something else I guess , I'm assuming xd
Yes these problems are really frustrating and common. I sometimes work in a pc store and we just put a new board in. No one is paying that amount of money for the time to locate and fix those issues.
Exactly I was going to say that no one wants to pay for you to fix the issue. They just want quick and cheap. Plus, getting replacement parts can be a real pain as well. A lot of times if it's 3-5 years old just get a new laptop.
My g14 screen broke when i fell off my board onto the road. Big dent on the lid corner but the bezel is still perfectly fine, screen is a bit dented and needs replaced. I bent the lid back to shape with pliers to fit the bezel now im just waiting for my screen to come in the mail 😄👍🏻
Funny enough I also recently had to a replace a cooling fan on my Asus laptop that was literally 1 day out of warranty when the problem started. Fortunately my repair worked. But it was fun to watch you troubleshoot what on the motherboard was causing the issue because at that point I would have just trashed the whole board lol. I have to say console videos are good too but I really like seeing the pc repairs.
Not sure if you have heard of freeze spray before. Its a cryogenic spray that you apply on a suspicius area on the board and the hot components melts the frost immediatly. Its also a dry form of frost so you dont contaminate the area with moisture.
A little tip incase it helps for future reference: use a rubber band for stripped screws. If you place a rubber band over the screw then press your bit into it, it gives better traction to remove the screw
It may help you. You could check the screw holes in the mother board, specially heatsink screws. Sometimes ir you tight them todo hard, cuper layers in the motherboard just touch each other and may cause this kind of shorts. And since it was the only part for sure handled
The most fascinating thing about these videos is imagining the kind of people that attempt repairs like this themselves. How do they function day to day? How do they even wipe their own arse.
Usually when there are multiple shorts like that throughout the board, it's almost usually conclusive that the CPU or GPU (Maybe both) are shorted within themselves. Checking the caps for shorts right under them can help determine that. . . Btw just a huge thanks to what you do! I learn a lot from your videos and I enjoy seeing new strategies and tricks to solving a problem!
Yep, seen boards like this before. The easiest thing to tell the customer is to buy a new laptop, the old one is too broken to get fixed. They can feel free to get a second opinion.
I got super excited when I saw the thumbnail cause I just happened to buy this exact laptop this year, and was really looking forward to seeing it fixed incase I came across problems in the future. Hope you can revisit it at a later date. P.S. Your vid on the Elite Series 2 controllers was a huge help, and I did 4 of them myself with your vids help.
He wasn't checking for shorts at the start, kinda odd unless he did it off camera. It's one of the first things I do before trying to inject power anywhere.
Currently watching this video on that exact model laptop! Really cool to see you take it apart! I actually also had to have my fans replaced at one point because the gpu fan was totally broken, and currently my cpu fan works but is a lot louder than it should be. I've uhh dropped it a couple times.
As for this laptop you can still earn money flipping the parts altogether I feel like, at least the ssd should be a fair bit more than the other parts, you could probably get a bit of extra money from that than an actual repair since the motherboard is completely shorted.
You’ll get lucky one day! These computers and cameras are very complicated. After watching Luis, I feel like I can repair anything until it’s in my hands.
If everything worlds besides the main board you can probably easily sell the shell for that cost your paid. With laptops the keyboard is built into the bottom casing making that a super easy sell!
That's all factory thermal paste You had 20v for the main rail after you replaced the ic you had a short on the main voltage rail 1285A is the 3,3v and 5v rail to supply rest of the laptop When you replaced the chip something went wrong and send 20V to the 3,3v rail by the mosmet that was shorted. 1285A has 2 LDO reg one for 3,3V (pin 3) and one for 5v (pin 13) if one of the LDO were shorted that could cause the chip to heat up. looks like you killed the board time 14:27 that chip is for 3,3v and 5v switch to the rest of the board confirming my suspicions that 20V went on the 3.3v rail that would kill most of the chips on the board 😢 Still a good video 👍
@@AnonymousRepair re-watched the video again with focused mind, yup my man you are right, he possibly shorted two power rails on his first soldering attempt
The "missing" hingescrew is for the bottom case. The coaxial cables are supposed to lay on top of the heatsink. MB usually have 2 -4 screws with many being screwed in from the bottomcase (usually 1-2 top, 2-3 on charging port side, 1-2 IO or left side). Rarely in the middle and rarely in the bottom due to the battery being screwed in.
In the video at 7:21, the component on the right side , with P1524 written on it, seems to be broken with a big crack through almost half of it. The two holes with broken "red paint" in 7:17 that you circle around also seem to have been pierced. It probably has nothing to do with the problem, but since I saw it, I wanted to let you know. Maybe it helps.
Do you ever just do a deep clean on boards that have no apparent cause for the fault? One time I had a board that worked one day, didn't the next and I just gave everything a quick iso bath with toothbrush scrub and when I plugged it in it worked! I looked in the cleaning tub and I found a *tiny* little strand of something, tested it and it turned out to be conductive. I didn't see exactly where it came from but I'm guessing that it was lodged between two components and was causing a short. Now I start all my troubleshooting with a scrub-a-dub-dub.
Having owned a g14 for ~2 years, I think you might have two separate issues here. The fan bearings on the early batches notoriously fail within a couple of months. The second issue is a power management problem. The laptop supposedly fails to disable usb-c charging when the barrel jack charger is plugged in. According to the g14 subreddit, it’s possible that the machine could even start on fire. Lucky you! This particular machine has both issues! :P
Before trying in depth repairs like this on laptops, you should try a "discharge" or "de-static" procedure on it. 1. Disconnect the battery and CMOS battery if possible 2. Hold the power button for at least 1 minute 3. Reconnect CMOS battery, but not the main battery 4. Connect the charger 5. Attempt power on I've saved many a laptop this way, and it was first told to me by HP support for a DOA laptop, which it fixed! 👌
Just to add, some modern laptops may need the battery connected to power on, so you may need to reconnect the battery and charger and test power on after the procedure.
At 7:21, the chip p 1521 looks to be cracked on the left side Maybe replace that? Anyways, Asus laptop fail the most and i sadly i too have one and i am scared it will die 🤣
From my experience, they are much, much better than Acer, HP, Lenovo and Razer (especially!) laptops. Are you sure? Personally (I know, it is just me) I never had any issues with them - still have ROG with i7-6800hq and 960m working without any issues as a backup.
Literally just did the same repair (and upgraded the thermal paste) on the same laptop 2 weeks ago, no problems, took my time as I'm not particularly skilled in this area but followed an online guide and it went smoothly. This "repair" was hard to look at
If I remember correctly the Asus Zephyrus G14 uses liquid metal by factory, so it is possible that when it was taken apart for cleaning by the previous owner liquid metal is leaked and created short circuits, although visually I did not see any traces of liquid metal.
The ohm reading at the current sense resistor (1ohm) indicates that the component that has failed is less likely to be a high-side mosfet causing a reading through processor or pch but more likely a smd ceramic capacitor or an IC that has VIN. I doubt you have PCH or processor failure, because 19V generally doesnt go directly to processor or GPU or pch or memory unless of a high-side mosfet short which couldnt be possible because of the 1ohm to ground reading at the charging IC current sense resistor. The board is still very likely fixable. Howcome the short isnt producing heat ...i dont know...maybe leave the board connected to the short killer for some time maybe eventually enough heat will be produced.
If I had to guess from the extremely lose screws on the heat sink it is possible that the person that previously owned it ran it and extensively overheated the GPU/CPU causing it to melt some of the solder balls shorting out a bunch of things
Excelente video hermano, me fascina este tipo de reparación y la paciencia para analizar cada componente. Se que la puedes reparar! Parte 2 porfavor 👍🏼👍🏼👍🏼
I’m an ex-chef who got a law degree in my mid life and a part time laptop assassin. I get so much pleasure in watching people do things that I wouldn’t stand the remotest chance of being able to do. If I so much as breathe on a clip it disintegrates and I’m the guy who is dangerous with a multimeter in my hand.
I know, right? I'm a law undergraduate and an involuntary tech murderer as well (don't know if those two things are related). I've learned so much about technology simply because it keeps breaking on my hands despite my best efforts. I treat all my devices like princesses, and yet they still act like they're being thrown around 24/7. I've gotten to the point where I avoid touching other people's devices in fear of making them explode somehow.
Learn more watching this channel than most . Then simple quick explanation on what your doing eventually starts making sense to someone green thank you this is such a essential skill to know with all the planned obsolescence these days.
Seeing the many missing screws, and screws not properly tightened. I suspect whoever tried to fix the laptop before, probably long-screwed a short-hole and broke the motherboard.
Yeah, seeing screws like that is a good sign somebody who doesn't know what they're doing did bad things to the board beyond whatever the initial problem was.
I own one of these laptops myself and it pains me to see how this one was brutalized. Would love to see a follow up on this one though I imagine without schematics its probably not reasonable. However, this is a fairly new laptop and should be under warranty so im very suspicious that this was a botched fan replacement. Sounds like the seller to me probably knew what really happened to it and was trying to make a quick buck.
I own a G14 as well and as a novice, I did look into things I can do to upgrade/modify the laptop. One of the things I discovered early on in my search is that if you do disconnect the battery and are not careful in doing it, you can easily drop it into a line and short the board. This combined with the comment I read here earlier about everything sharing the same power rail leads me to believe that the prior owner tried to replace his fan, wasn't careful about the battery connector, and zap.
I have recently started watching your channel and love your videos! It has inspired me to start working on electronics, because I enjoy it, but also to help pay the bills. I just found out about your online soldering courses, and have started the free soldering for beginners course. I am really enjoying it so far. I am wondering if you would consider making a course on the electrical side of repairing electronics. After going through the soldering courses, I will know how to solder, but I will not know how to figure out what components I need to solder. I have a decent multimeter, but I just do not know how to use it effectively to determine what components are bad. It would be really cool if you did a course showing how to set up and use a multimeter and how to diagnose shorts and faulty components on the board. Again, your videos are awesome and keep up the good work!
I recently changed the keyboard on my Dell G5. When taking it apart I noticed that there were what looked to be missing screws. But upon closer inspection I came to realize that they were not missing. The screws were the ones that also held the covers in place. So nothing was missing.
I would be very grateful if you could make a video about Amazon Fire Tv Sticks how to fix HDMI port or any problems with the device. You're doing very well, keep it up!
Another thing I found out with these gaming laptops is that they need both the battery & power cord in order to fully power the GPU. In cases where the laptop will even power on w/o the battery & just the cord, the GPU will be in some sort of limp mode.
Just a wild guess based on some observations I did back when I studied electronics. But it was not uncommon when voltage went the wrong spot, for multiple components to die in the process before the fuzes went off. If everything is shorted its hard to tell if any fuzes went or not without disconnecting them all. So chances are that board just got thoroughly fried at some point. Shorts in computers can reach the melting point within seconds.

We seem to be glossing over how someone so thoroughly destroyed this computer in their repair attempt. I find it impressive.
: ) yeah clean the fans is lesson #1 as well, ha ha. Lets hope they learned something (other than the repair sucked)
yeah that thing was mangled. I couldn't believe the screws that were in there were so chewed up, but yeah, this made me cry a bit....
Clearly, the former owner of that laptop can NOT have nice things.
I need your help for my game console
yeah lol... clear example of why some people should really avoid try fixing electronics if they have no idea what they are doing...
This seems to be the result of bricking the laptop after plugging in the USB-C power along side the DC power chord. This model had that issue for many owners on the 2020 model. It was fixed on the 2021 model

That's a good point. Zero ohm links are supposed to be for connecting traces between layers and not necessarily intended as fuses

I was really hoping you would get this one fixed. You were extensively thorough. I always look forward to your content. Thanks for sharing.
I imagine that everything shorted shares the same power rail, and that that rail is shorted to ground where it is produced from the 20v in.
That's what I'm assuming as well.

Yeah I was a bit annoyed by that when I bought my g15
you can buy version with 16GB soldered and add 16GB DDR4 stick to have total of 32GB
Hmm mine had the whole 16GB soldered on the board and an open slot so I was able to upgrade it to 32GB.

1285A has 2 LDO reg one for 3,3V (pin 3) and one for 5v (pin 13) if one of the LDO were shorted that could cause the chip to heat up.
looks like you killed the board
time 14:27 that chip is for 3,3v and 5v switch to the rest of the board confirming my suspicions that 20V went on the 3.3v rail that would kill most of the chips on the board 😢
Still a good video 👍
the chip he replaced was a usb C battrey charging chip from mouser part number ISL9283

@@AnonymousRepair re-watched the video again with focused mind, yup my man you are right, he possibly shorted two power rails on his first soldering attempt
He removed 1285A and then immediately soldered a new chip.
He should have continued checking for shorts, after removing 1285A.
@@sixcoregamer9221 True but you can't check for shorts if the mosfet gate is floating, sometimes the mosfet will fully open with no ic installed
The "missing" hingescrew is for the bottom case. The coaxial cables are supposed to lay on top of the heatsink. MB usually have 2 -4 screws with many being screwed in from the bottomcase (usually 1-2 top, 2-3 on charging port side, 1-2 IO or left side). Rarely in the middle and rarely in the bottom due to the battery being screwed in.
We need more laptop videos ☺️
Two thumbs up, from the UK, for the use of the saying '...buggered up'!
In the video at 7:21, the component on the right side , with P1524 written on it, seems to be broken with a big crack through almost half of it. The two holes with broken "red paint" in 7:17 that you circle around also seem to have been pierced. It probably has nothing to do with the problem, but since I saw it, I wanted to let you know. Maybe it helps.
Yeah man I was looking for this comment since I noticed the same.
I'm glad I can watch you tinker with these electronics, I can't seem to get my hands on anything except old modems and sound systems that are fried
Do you ever just do a deep clean on boards that have no apparent cause for the fault? One time I had a board that worked one day, didn't the next and I just gave everything a quick iso bath with toothbrush scrub and when I plugged it in it worked! I looked in the cleaning tub and I found a *tiny* little strand of something, tested it and it turned out to be conductive. I didn't see exactly where it came from but I'm guessing that it was lodged between two components and was causing a short. Now I start all my troubleshooting with a scrub-a-dub-dub.
I once had a mainboard to a TV that was Roche invested. Poured ISO on it scrub with a TB let it dry board worked fine.
Steve you don't usually have music in your video's right? I found it a little off putting. Still love the channel 👍🏻
Having owned a g14 for ~2 years, I think you might have two separate issues here. The fan bearings on the early batches notoriously fail within a couple of months.
The second issue is a power management problem. The laptop supposedly fails to disable usb-c charging when the barrel jack charger is plugged in. According to the g14 subreddit, it’s possible that the machine could even start on fire.
Lucky you! This particular machine has both issues! :P
Before trying in depth repairs like this on laptops, you should try a "discharge" or "de-static" procedure on it.
1. Disconnect the battery and CMOS battery if possible
2. Hold the power button for at least 1 minute
3. Reconnect CMOS battery, but not the main battery
4. Connect the charger
5. Attempt power on
I've saved many a laptop this way, and it was first told to me by HP support for a DOA laptop, which it fixed! 👌
Just to add, some modern laptops may need the battery connected to power on, so you may need to reconnect the battery and charger and test power on after the procedure.
You should send this to Northridgefix for him to look at
I doubt it, Northridgefix usually doing simple and quick repairs
Not sure if someone else already commented on this but at 7:22 there is a component that seems to be cracked (reads P 1524). Did you notice that?
At 7:21, the chip p 1521 looks to be cracked on the left side
Maybe replace that?
Anyways, Asus laptop fail the most and i sadly i too have one and i am scared it will die 🤣
I saw the same thing had to rewind and look again but that's what I see
From my experience, they are much, much better than Acer, HP, Lenovo and Razer (especially!) laptops. Are you sure?
Personally (I know, it is just me) I never had any issues with them - still have ROG with i7-6800hq and 960m working without any issues as a backup.
@@ibiggphi79 same. I suspect that it must have shorted the contacta which could be causingthe issue.
@@andyblondyn1898 i have one from about an year as compared to acer travelamte 0214-52, Asus isn't the best.
That's a resistor and the line is there from a multimeter probe slipping on it. It doesn't matter at all.
Literally just did the same repair (and upgraded the thermal paste) on the same laptop 2 weeks ago, no problems, took my time as I'm not particularly skilled in this area but followed an online guide and it went smoothly. This "repair" was hard to look at
Whoever tried to repair that previously has butchered it.
BIG TIME
All I can think off is faulty cpu! The short circit is in the cpu.
It is interesting of how you troubleshoot.
Thank you making this video!
Had same laptop, died two days after I got it. Wonder if it was a similar problem
If I remember correctly the Asus Zephyrus G14 uses liquid metal by factory, so it is possible that when it was taken apart for cleaning by the previous owner liquid metal is leaked and created short circuits, although visually I did not see any traces of liquid metal.
Please don't play music when talking. It only hurts accessibility :(
Loved the rest as always
Yes. I needed something fun on this Friday morning!
The ohm reading at the current sense resistor (1ohm) indicates that the component that has failed is less likely to be a high-side mosfet causing a reading through processor or pch but more likely a smd ceramic capacitor or an IC that has VIN.
I doubt you have PCH or processor failure, because 19V generally doesnt go directly to processor or GPU or pch or memory unless of a high-side mosfet short which couldnt be possible because of the 1ohm to ground reading at the charging IC current sense resistor.
The board is still very likely fixable.
Howcome the short isnt producing heat ...i dont know...maybe leave the board connected to the short killer for some time maybe eventually enough heat will be produced.
If I had to guess from the extremely lose screws on the heat sink it is possible that the person that previously owned it ran it and extensively overheated the GPU/CPU causing it to melt some of the solder balls shorting out a bunch of things
Excelente video hermano, me fascina este tipo de reparación y la paciencia para analizar cada componente. Se que la puedes reparar! Parte 2 porfavor 👍🏼👍🏼👍🏼
I’m an ex-chef who got a law degree in my mid life and a part time laptop assassin. I get so much pleasure in watching people do things that I wouldn’t stand the remotest chance of being able to do. If I so much as breathe on a clip it disintegrates and I’m the guy who is dangerous with a multimeter in my hand.
I know, right? I'm a law undergraduate and an involuntary tech murderer as well (don't know if those two things are related). I've learned so much about technology simply because it keeps breaking on my hands despite my best efforts. I treat all my devices like princesses, and yet they still act like they're being thrown around 24/7. I've gotten to the point where I avoid touching other people's devices in fear of making them explode somehow.
And I'm batman who got a superhero degree in my mid life and a part time bat imitator.
Learn more watching this channel than most . Then simple quick explanation on what your doing eventually starts making sense to someone green thank you this is such a essential skill to know with all the planned obsolescence these days.
Seeing the many missing screws, and screws not properly tightened. I suspect whoever tried to fix the laptop before, probably long-screwed a short-hole and broke the motherboard.
Yeah, seeing screws like that is a good sign somebody who doesn't know what they're doing did bad things to the board beyond whatever the initial problem was.
Great video Steve! Sucks that whoever tried to repair it didn't even try to do a good job putting it back together.
I cant say I've ever heard an American say "buggered up" before
Haha, nor me 🤣
I watch some repair channels from the UK. Probably picked it up from them.
Sent to Northridge Fix. He will find the short in 1 minute. Northridge Fix is great UA-cam channel. I’ve learned so much from him.
I own one of these laptops myself and it pains me to see how this one was brutalized. Would love to see a follow up on this one though I imagine without schematics its probably not reasonable.
However, this is a fairly new laptop and should be under warranty so im very suspicious that this was a botched fan replacement. Sounds like the seller to me probably knew what really happened to it and was trying to make a quick buck.
I think that commenters are often too ready to blame 'human factors', but in this case I think you are 100% right.
I own a G14 as well and as a novice, I did look into things I can do to upgrade/modify the laptop. One of the things I discovered early on in my search is that if you do disconnect the battery and are not careful in doing it, you can easily drop it into a line and short the board.
This combined with the comment I read here earlier about everything sharing the same power rail leads me to believe that the prior owner tried to replace his fan, wasn't careful about the battery connector, and zap.
Probably shorted the Super IO chip. Or the part of the southbridge that deals with SIO. It is integrated into chipset on later MOBOs.
crack on 7:21 (component 1524)
Same here , it seems like it could be the cause.
Good eyes but that's just a scratch on it, not an actual crack.
I love your content. You're not only talented, but a good presenter too.
5:21 it's not a thermal paste, it's kinda "liquid thermal pads"
So a paste then. A paste is a liquid it has a high viscosity and a low fluidity.
Actually it's viscous thermal paste.
1:25 them are the holes for the screws that hold the case on not missing screws 😄
The seller was not honest with you. That laptop has too many problems. Very good video.
I have recently started watching your channel and love your videos! It has inspired me to start working on electronics, because I enjoy it, but also to help pay the bills. I just found out about your online soldering courses, and have started the free soldering for beginners course. I am really enjoying it so far. I am wondering if you would consider making a course on the electrical side of repairing electronics. After going through the soldering courses, I will know how to solder, but I will not know how to figure out what components I need to solder. I have a decent multimeter, but I just do not know how to use it effectively to determine what components are bad. It would be really cool if you did a course showing how to set up and use a multimeter and how to diagnose shorts and faulty components on the board. Again, your videos are awesome and keep up the good work!
I really liked this style video. Very in-depth troubleshooting. Please do more like it.
I recently changed the keyboard on my Dell G5. When taking it apart I noticed that there were what looked to be missing screws. But upon closer inspection I came to realize that they were not missing. The screws were the ones that also held the covers in place. So nothing was missing.
I would be very grateful if you could make a video about Amazon Fire Tv Sticks how to fix HDMI port or any problems with the device. You're doing very well, keep it up!
I really admire your patience when fixing things, keep it up.
Great Content. This community seems to be very healthy overall. KUDOS to you all!
Maybe it did have liquid damage, but got cleaned? Do you have ultrasound cleaner or something like that?
it's impressive how whoever tried to replace the fans (why would you?) managed to fry every component, even the screw
Great video Steve, pity you couldn't sort it out , but it just looks like a minefield of problems..
There is free boardviews for most MBs, you just have to do comprehensive searches to get around the pay sites.
Another thing I found out with these gaming laptops is that they need both the battery & power cord in order to fully power the GPU. In cases where the laptop will even power on w/o the battery & just the cord, the GPU will be in some sort of limp mode.
I have a G14 2021 (2nd Gen) model that looks exactly like the one in the video and my laptop has been amazing.
Just a wild guess based on some observations I did back when I studied electronics.
But it was not uncommon when voltage went the wrong spot, for multiple components to die in the process before the fuzes went off.
If everything is shorted its hard to tell if any fuzes went or not without disconnecting them all.
So chances are that board just got thoroughly fried at some point. Shorts in computers can reach the melting point within seconds.
Look at 7:21 , there is a crack
@@lacucaracha111111 Nice catch, I didn't even notice that. But tbh. it looks more like a scratch to me.
Steve P 1524 Chip has a crack left side and has something to do with Output Voltage according to Google.
Give Northridge's channel a look. Maybe that'll help
Sounds like a challenge to Northridge Fix repair shop from California
"The screws are all buggered up" That was funny.
Nice vid. I like how deep this vid went with the troubleshooting.
