This channel has three main characters: Alex, Big Boss and Asus products.

Even the repairs that aren't successful are still great to watch. 👍

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!

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.

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

Narrowing the problem via ohms mode is something new to me. Looking forward for 2nd video. 😉

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. 🙏

HOPE THERE IS A PART II OF THIS VIDEO. GREETINGS FROM ARGENTINA

You always make me laugh.. lol.. thanks a million for all the great trouble shooting, repair and humor..

I enjoy watching you work and figuring out the problem , you do quality work , no B's , good job my friend

So interesting to see every video that you made.

Atk1604 It’s pwm controller of cpu, you can change atk1604, but most likely the problem with cpu

that was those are the days that you really need a ton of patience keep up the good work

Waiting for part 2 of this video. Hope you can do it Alex👍

Thank for video👍

I like when Alex says that's a good question.

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.

Thank you for this video. We learn more from failures like this.

Hello Mr better than factory joints 👋

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?

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 KZfaq". 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

Enjoying whether fix or not fix very interesting to watch. Thanks

power mosfets are like low-ranking wrestling heels of electronic repair. Easy to beat yet mildly entertaining.

As always interesting.

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)

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 😀

Looking forward for part 2

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 🦾

May be replacing the driver IC can solve the problem! Alex thank you I got a lesson on that even though not fixed.

Good job mate 👍

Love the vids

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

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.

i salute you sir.., Godbless 🙏🌱

Great work video to watch

So KZfaq 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.

Enjoyed the video

Good luck with it. 😁

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 🙏

An Asus laptop add played while watching this video. 😂Great video as always Alex.

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 😱

you should also test the drain and source

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.

2nd Sequel is highly awaited

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.

Please make a part 2 of this one. It's a head scratcher!

am still beleiving in you alex

Awesome ✌🏻✌🏻✌🏻

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 :)

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

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.

you may wish to look at the mosfet in 18.35 it looks like there was overflow to the gate shorting it out.

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…

Very nice sir 💯😁✌

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

I'm thankful for this channel. I won't be buying Asus products.

"SNAP - you got the power" would be a great tune, or better "Joe Esposito - you're the best around" to encourage Asus Laptops

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.

nice Vedio ☮️👍

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?

What if you inject voltage into the small mosfets?

Nice

4:25 when you see meter in diod mode where did you put the red multimeter and the black?

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.

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 😶‍🌫

The problem is that there are some electronic items that are not available in the market

running gag... "here we have another Asus Laptop" :D

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

So when are "the short is back" t shirts becoming available?

if what aliexpress shows is accurate that is a ethernet chip though some sites say its a surge absorption ic

ATK160** is a voltage regulator chip

Is Different breed Asus Q526F but is the same 💩is good for you Dr Alex ❤more surgeries

i think the problem is coming from that chip if the processor is shorted it should so heat from your thermal camera

Classic Asus

hi i would check the controller chip . sometimes it get shorted and 19v staright to pop the fets

That's becoming a feature and not a flaw for Asus products.

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

6:45 looks like cpu is also getting hot at the same time with atk chip, maybe cpu is toast ?

why so many mosfet failure .. may be something problem in the board....

That chip is only available on aliexpress... Can't find the original manufacturer or spec sheet on it.

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...

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

"When in doubt, just replace" I wish we could do this with half the people under 21 and their crappy parents these days.

That's way we do a visual inspection microscope

part 2 please!!!!!!

It surely has to be the chip that was heating up.

I don't understand people complaining about not seeing the voltmeter though. :D

it is cpu power ic ATK1604BH

can we fix it

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?

Alex.. whenever you're angry with an Asus motherboard say 'What The Asus'

its the atk chip common problem

Thanks to Asus

Big boss i had the same issue, the cpu was causing it

Cliffhanger!!!
