This channel has three main characters: Alex, Big Boss and Asus products.
And every Asus is a boss-fight.
Right
Big boss😏
Fixed: BTF now
Asus play with mr. Alex
Even the repairs that aren't successful are still great to watch. 👍
The process for quickly identifying faults is the skill most suited to learning from a video. Actually repairing them is something you kinda have to learn from doing, not watching. At least that's been my experience.
@@christopherjackson2157 Yeah I have to agree. I've tried a few things that I thought I could do but ended up out of my league. He does make things look rather easy. Good tools and equipment helps but even so, they are useless in the wrong hands.
Yes they are! They are lessons you learn.
I live watching these videos because they learn me stuff and most of all learn me to be patient when repairing stuff.
@@SPEXWISE start small and work ur way up. If you haven't done something before find a piece of dead hardware and do a test run on it before working on the thing you want to fix. The second time you do something is always gonna turn out infinitely better than the first. It just takes practise.
And yes he does make things look ridiculously easy lol. It's really amazing to watch him work. :)
jeeez spoiler alert :)
As a retired service tech since tube days thru cds up to big screen tvs, when I need my FIX I like to stop in for the journey! Love the Videos! Congrats to you sir, on knowledge, skills and all you do!
Atk1604 It’s pwm controller of cpu, you can change atk1604, but most likely the problem with cpu
Man, Alex is just in another level. All of a sudden the camera gives up, environment goes dark but the Man just keeps going.
Taking measurements in the dark. Wow! I bet none of us saw that coming.
Narrowing the problem via ohms mode is something new to me. Looking forward for 2nd video. 😉
HOPE THERE IS A PART II OF THIS VIDEO. GREETINGS FROM ARGENTINA
Yeah i hope also.
The fact that this is "not a regular Asus laptop that we fix" says quite a lot. I wonder how many of those remain on the shelves purely because of your videos. Great work, as always
Can't seem to find chip's datasheet, but it might be "the shorting mosfets" driver.
Getting hot isn't normal so it may have become so sensible, and just instructs all mosfets to turn on when power is available, and in case of an H-bridge or half H-bridge instructing all of them at the same time will cause a short.
The only real comment indicating the problem. Congrats!
I am the same way about things when I've put in a lot of time and effort to repair and then it still results in failure.
All you can do is keep striving to do better.
We learn from our failures.
Great Show!
Thank you bro. I always learn something new from you. Like checking fault using ohm mode, injecting voltage, not to test capacitor or board when it is still hot. Keep up the Good work and we thank the lord for selfless people like yourself. 🙏
I enjoy watching you work and figuring out the problem , you do quality work , no B's , good job my friend
this thing happened earlier with me , look at board view there must be a 0 Ohm resistor blown near atk chip (in my case this happened)
You always make me laugh.. lol.. thanks a million for all the great trouble shooting, repair and humor..
So interesting to see every video that you made.
Waiting for part 2 of this video. Hope you can do it Alex👍
that was those are the days that you really need a ton of patience keep up the good work
Enjoying whether fix or not fix very interesting to watch. Thanks
May be replacing the driver IC can solve the problem! Alex thank you I got a lesson on that even though not fixed.
I like when Alex says that's a good question.
Thank you for the video. Looking forward to a part two on this board when you get in the IC new chip. Also is that a crack in the MOSFIT below 4C09B at 5:17?
Hi Alex, good video, i would suspect that chip specially if it controls the gates. Replace the chip then inject voltage again. Then new mosfets and test the whole thing. Have a nice day.
Thank you for this video. We learn more from failures like this.
Alex. If you need some cheering up. I recently replaced the power connector and a USB port on a co workers Asus lappy.
It's not good when the tab on a USB breaks and you can plug in the cord, device either way. Right!
Well. Of course I did the repair like a boss. Not like The Big Boss. I like every one of your videos. And the look on your face when you succeed.
So...The guy, one of my techs. Asked how I did it and what equipment I have at home. What are you gonna' do?
"Watch Northrdge Fix on UA-cam".
I guess he did. And some of the girls too. Especially the one I replaced a screen on her cell phone for.
So what do I start hearing around the shop? In your distinct voice and accent.
If something, anything happened. Literally.
"Needs-more-Amtech-flux". And "Better-use-559-this-time". A machine broke, my tech fixed it. Across the shop I hear him say...
"Better-that-factory". If he didn't have parts, "Whatta'-ya'-gonna'-do?". Oh it gets better. Wings and beer night at the local sports bar.
Wings are good. Beer is cold. A few of us are there from work. Someone buys me a beer when mine gets low. What do I hear?
From across the bar, with a smile. "You-need-more-Amtech-flux". "Everything-we-drink-here- you-can-get-at-the-bar". "We-dont-serve-you-anything-that-we-don't-drink-ourselves".
Keep up the awesome work. You need an assistant. Seriously. If he/she can pump them out.
smile on the face is amazing when finds a short its like beginners first time luck
Hello Mr better than factory joints 👋
This is why I always buy graphics cards and motherboards based on vrm design. Better vrm = more efficient = less heat = Increased lifespan = less work for Alex 😀
less work "ALEX IN SAD MODE"
There are many many many more factors.. Vram quality, PCB layers, quality of the soldering, etc
Wtf does this have to do with a laptop motherboard
power mosfets are like low-ranking wrestling heels of electronic repair. Easy to beat yet mildly entertaining.
due to this type of problems the store where i did buy my asus rog strix g15 2021 model, took it back after 3 times being repaird and between repair its just worked 5 days. got 3 new motherboards in total and two times is was already broke when it came back. it seems like asus need to get beter at this i know there were poeple who bought it and got it broken in the box due to bad chips.
like you work keep it up. i know what happend to my asus laptop tnx to your vids
Sometimes it's a deeper rabbit hole than thought before.
Even if you can't fix the issue; the way you approach an issue, is so much educational to us viewers.
Every video (If I may speak for the rest of us) we learn something new.
I repair old Professional Broadcast CRT Monitors without an Service manual. It made me very flexible in approaching any device with a issue and try to investigate en know whats wrong.
Your videos has helped me with the basics more than any other video out there.
I thank you.
Love the Channel and keep up the incredible educational videos
to keep device away from the garbage 🦾
Thank for video👍
Everytime i watch your videos, i learn more and more, my soldering skills are getting better and better, that is 90% thanks only to you.
I just wanted to say thank you and best greetings from germany 👍
In germany we use flux from the company Stannol, its almost as good as Amtech, but its yellow after melting and you would hate that, i know for sure xD.
I would love your hot tweezers, if you get a new one, i would love to get my hands on your old ones 😂
I saw at a benz key video, once there was a bent one cause it dropped down maybe...
I would bent it back to normal and make it useful again for my own soldering station.
I also love to make useful things outta others trash 😂
People like you, who share their knowledge are the best, you should get a statue in northridge caused by your genius.
Thank you very very much for teaching us (and also for free)
I will open up a shop like yours someday and hopefully i will get good enough to make it for a long time. Best wishes for you and yojr family, sry for my bad english and stay healthy 🙏
Greetings from Südbaden Huttingen!
As always interesting.
Alex has precision hands, like a surgeon. Not that I have shaky hands but when I do precision work on tiny stuff, I can’t hold steady. Lol Like trying to thread a needle 🪡.. whoosh 😱
Looking forward for part 2
Good job mate 👍
It could very well be a failure of the PWM controller. If somehow it always pulls the gate high, it will fry all related power MOSFETs.
From what it seems, whatever is driving those MOSFET's is likely the culpret. Whatever IC is driving the FET's is likely killing them due to an overvoltage to the Gate and Source. It's not normal for multiple MOSFET's to fail on a board the same way.
If the PMIC gets hot on the gate driver pins, it's surely toast.
Wanted to maybe get you thinking about buying land and building your own house.
That way, you know that everything is done right and it fits your needs.
There are plenty of home kits you can buy and then add on later.
If you know an architect then get with them and see what they can come up with.
Also make sure your builder is honest and using the best materials.
Know your materials and watch that the builder is using the right ones.
There are standards for how hard concrete should be and how many nails to put in a board and the size of the nails etc.
You could have a house built that you could finish the inside of certain rooms later.
You are going to get what you pay for in home building but that's if you watch everything.
I like French Country style homes as they are very stylish and easy to take care of.
Good resale value too.
Love the vids
The thermal suggests the chip is keeping the MOSFETs on so they blow. The chip should have protection against supplying to much current to cpu so I'm guessing pwm chip only problem. Good luck
You should pre produce an Intro saying „Here we have an ASUS Laptop that came in for no Power“. You would save so much time :)
An Asus laptop add played while watching this video. 😂Great video as always Alex.
Great work video to watch
you should also test the drain and source
i salute you sir.., Godbless 🙏🌱
Hi Alex. What happens if you remove the ATK chip entirely and then check for a short? usually that ATK chip doesn’t go bad…
Enjoyed the video
Please make a part 2 of this one. It's a head scratcher!
18:27 when you soldered that chip on, it looks like some of the pins connected with solder. The solder on the third pin on the top edge formed a blob. That blob looked like it connected to the pin to it's left.
They're on the same pad so it won't matter if the solder bridges the pins.
Good luck with it. 😁
you may wish to look at the mosfet in 18.35 it looks like there was overflow to the gate shorting it out.
What if you inject voltage into the small mosfets?
ohhh this is very very annoying. I hope you find the error and it's really because of this one chip. Looling forward to see a second part of it. Thank you for that video, greets
"SNAP - you got the power" would be a great tune, or better
"Joe Esposito - you're the best around" to encourage Asus Laptops
The problem is that there are some electronic items that are not available in the market
So UA-cam is showing an ad for ASUS laptops on a video with a defective ASUS laptop.
Good work Google you're the best.
Never buying ASUS laptop again.
maybe the problem could be the pwm controller, somehow it doesn't switch correctly sending both mosfets into conduction creating a short circuit between the positive of the first mosfet and the ground of the second one
why so many mosfet failure .. may be something problem in the board....
Question : do you have 9410AGM mosfets at your store? Searched on the website but couldn't find it but i remembered you once said that not all your items are on the site atm. Hoping that's the case lol, it's for my Asus ROG Strix GL753VE.
am still beleiving in you alex
Excuse my ignorance, but when your probing around looking at the Vf for the MOSFETs, finding shorts, etc., where is the other probe? Just on ground somewhere on the board? Is the meter set to continuity?
In my experience something begin to hot you should always change that part. in this case very first you injected voltage that chip begin to hot
How often do you get other breed of Asus laptop? Like Zenbook, Vibobook, Expertbook etc? Or mostly ROG laptops goes bad often?
I just bought new ASUS G15, which is often present on this channel. Fingers crossed 😶🌫
good luck 🤞🤞😂😂
hi i would check the controller chip . sometimes it get shorted and 19v staright to pop the fets
i think the problem is coming from that chip if the processor is shorted it should so heat from your thermal camera
Very nice sir 💯😁✌
That chip is only available on aliexpress... Can't find the original manufacturer or spec sheet on it.
2nd Sequel is highly awaited
can we fix it
if what aliexpress shows is accurate that is a ethernet chip though some sites say its a surge absorption ic
running gag... "here we have another Asus Laptop" :D
yeah it reminds me of masterlock locks at the channel "lockpicking lawyer"
When they're on you know they will fail badly even at their top models. Lots of fun for the community 😁
nice Vedio ☮️👍
So when are "the short is back" t shirts becoming available?
Awesome ✌🏻✌🏻✌🏻
Hi. What do you think about this machine | TBK R-2201 Intelligent Infrared Laser Desoldering Welding Machine. Thank you in advance for you help. Regards
That's becoming a feature and not a flaw for Asus products.
6:45 looks like cpu is also getting hot at the same time with atk chip, maybe cpu is toast ?
Bro.. u don't have DC power supply?? I didn't see ur videos. And u also not used that to power laptop boards. When i study chilevel they told dc PS is impt one. ur legend. But u didn't use means.. how to find some faults easily. I think ur ultra legend in servicing...
I'm thankful for this channel. I won't be buying Asus products.
Am I crazy or is there a busted component at 4:09 in between the chip and connector and to the left of the lower number 1 silkscreened to the board?
Is Different breed Asus Q526F but is the same 💩is good for you Dr Alex ❤more surgeries
ATK160** is a voltage regulator chip
It surely has to be the chip that was heating up.
recently, my hp laptop stopped starting up and the electrician told me it is an issue with the mother board. I bought a used lenovo think pad laptop i5 gen. what can I tell you, this lenovo laptop introduced me to a new meaning or experience of using computers, it does not heat, it is quite, fast, and battery powers up the computer for a whole day long.
For the T-series .... Lenovo did a great job same as HP EliteBooks like 640 and 840. But Later T series are getting to thin ... to the point they contradict themselves in their roots of being tanks fo office and fiel applications. Latitudes ad Presicion as well. Any CORPORATE grade laptop will make. You can get gaming preformance on a Dell Precision Mobile Workstation .... and you will barely get issues at all. Of course, those are not glorified tablets.
I don't mean to underate you or your knowledge, but you were chasing false hope, it's almost a guarantee that the chip is the cause because you won't get 4 faulty mosfits at the same time on a such low power laptop
I was thinking the same thing. Why didn't he remove that ATK chip when under the thermal camera was the chip that was getting hot ?
@@floppydisk1137 i think because there is no case on desoldering such components if you don't has it to replace. So meantime he was doing what he can, checking mosfets. I think he explains these approach in another video
I understand why he tried that, because he can't source the other chip immediately so he attempted what he could right away.
He did it for the video
4:25 when you see meter in diod mode where did you put the red multimeter and the black?
Black you put to a global GND for many measurements. So I assume he did that :)
That's way we do a visual inspection microscope
there is a regulator mosfet with cracked neighboring from the mosfet i seen it the video he never notice that cracked in the middle from topmark of the component
"When in doubt, just replace"
I wish we could do this with half the people under 21 and their crappy parents these days.
So, the power delivery in this notebooks are lackluster compared with the power delivery in the rog desktop motherboards. ¿Why ASUS does that?
Could the charger be defective and delivers a destructive amount of power?
False. The charger convert AC to DC. If the charger is defective, the meter will not show 19 V. It will show 0 V instead. You can manually measure the charger with meter in DC voltage mode
I don't understand people complaining about not seeing the voltmeter though. :D
Nice
So what is the problem overall with ASUS? Is it that ASUS has a poor design that puts too much stress on the component or is it a problem of the chip manufacturer?
Asus is in the habit of using cheaper chinease components. This causes s lot of on board failures
Due to the fact, that asus laptops all fail in a similar fashion since a certain generation, it's safe to assume that their power distro design is borderline and it's not helped by buying and soldering the cheapest available components.
F.e. if you design a borderline power circuit due to budget constraints, you better make damn sure that the important parts are durable enough to hold out. If you however have budget constraints through bottomless GREED, you'll need to design a borderline power circuit with the cheapest and worst available components in mind. So to say, it's a wonder that ANY asus device comes out of a factory and does not die during the factory assembly and function test. Maybe they have removed factory tests altogether because every device would have failed XD rofl.
Putin.
@@chandramohannandanpawar2617 You can use cheap chinesse chips all day long with no problems as so many other brands so. As long as you do your QA homework, batch testing and so on. Issue is, they dont seem to care about quality. If the design is borderline, proper testing and stress process will reveal the weakpoints. Nothing new. Now, is up to you to improve your product or insist on selling it as is. Digikey is starting to list Chinesse parts and even some made in India. Some Chinesse brands do a really god job. ATX PSU's .... you dont expect to see Infineon Mosfets .... even in top brands. Some chinesse compannies do their homework right. It all about what are you willing to pay and your QA and responsability as a manufacturer
I don't believe the problem is with bad design. He's got mostly asus products for repair because Asus are the most popular and used brand of GPUs and gaming Laptops so that's why most of the repairs are Asus products.
do u have a logic board for IPAD7
Are there supposed to be black screens at min 13? Happens a few times.
no, I think there is an error in editing the video. I had to skip those parts.
I just noticed it. It appears to be a Problem with rendering. I'll fix it in UA-cam editor and remove the black Gaps. Thanks.
13:26 black screen
Alex.. whenever you're angry with an Asus motherboard say 'What The Asus'
