nice find haha

you killed me when you said لا حول ولا قوة الا بالله for a second i thought you were going to swear or use a strong language when the battery dropped , also i really like putting bloopers at the end of the video , it's super funny

Alex: "Wow, we did it." Me: Looks at time left in video "Uh Oh"

I also suggest, that you should replace the mosfet drivers, too. I had similar cases where only that could solve the prroblem. Or at least measure around the drivers.

Whenever I watch your repair videos i feel like a professional electronic repair man like you and look for non-functional appliances and attempts to repair

3:05, something on a cap.

As for me, PWM IC is operate the gates of this MOSFETS, so it must be change to.

Thank you for your great videos, very entertaining and helpful. I'm currently 15 years old and trying to perfect micro soldering and learning electrical circuits, since I find it fun, and these videos are very entertaining to watch and help me learn a bit.

Seen that behavior on laptops and video cards. Always came down to a faulty VRM controller. Don't know the root cause, but the MOSFET activation timing gets bad, from the controller, and it makes random driven MOSFETs short out between the gate and the source. Good luck!

Hi Alex,thanks for the video. I like the videos where you fail to repair stuff as much as the successful ones.The reason is YOU WERE LEARNING as you FAILED.Some people say :BUT YOU FAILED :No _ what you did was learn what did not WORK-in this particular case.The tough repair like this are the best teaching tools,in my opinion.You went for the most common fault in your view,and it was wrong so far,so do you give up,i hope not.At the same time i do realize you run a business and taking 1 hour to fix something is just not cost effective,but from a hobbyist point of view WE may spend ALL DAY trying to solve 1 laptop repair because it's usually out OWN laptop.haha So thanks for the no fix vids,they are just as important and entertaining as the completed repair ones.

A comfortable & confident person is willing to share their knowledge.

You can find similar cpu on graphic cards but do a thermal scan to find critical components and check if the fan draws more power than it should. Also inspect the board on the other side.

Is there any benefit to removing all the mosfets on a donor board and keeping them in a labeled compartment?

From Asus website. The two-color LED provides a visual indication of the battery's charge status.Refer to the following for details: Solid White : The Notebook PC is plugged to a power source and the battery power is between 95% and 100%. Solid Orange : The Notebook PC is plugged to a power source,charging its battery,and the battery power is less than 95%. Blinking Orange : The Notebook PC is running on battery mode and the battery power is less than 10%. Lights off : The Notebook PC is running on battery mode and the battery power is between 10% to 100%.

Looks like the charge controller is going crazy

Same thing was happening with me a year ago i was shocked to see that everything was fine on mother board no burns nothing. I cleaned it checked again still find nothing. Then at last after trying everything i put laptop in bag with Silica gel pouches on bottom middle and upper side and sealed the zip. And went for sleeping. Next day it was working like new and booted with just 1 touch. 😅 This experience was totally unexpected for me but learnt a valuable lesson that sometimes we have to take things easy not to make them complex by Overthinking. 😅

The gate signals should be supplied by a buck converter IC. Locate and swap that?

WOW ! The sharpie tip was awesome !

I would guess a disconnected mosfet gate rail if they turn on and off randomly. You can charge a disconnected gate with multimeter and then it can be turned on, as long as the discharge takes (that can be a long time is gates are eg. parallel and there is no circuit to blead it). Not sure if there is a case for that here, but often it can bite you unless you think of the high isolation and the gate capasitance than can keep it on even with power removed from it.

Thanks for the comment about the good repairability of ASUS' products. One reason that I'm looking at your videos is to get an idea about which are the electronics to steer clear of, because of either bad design or bad components and consequent consistent breakdowns. So keep those comments coming. They are much appreciated.

Any chance the power port is fractured and the power draw is just enough expansion to cause a fault ? Great video Great teacher Thanks again

Are mosfet drivers fine?

I LOLed when you dhikir after you dropped the battery in the end 😂. That's a rare reaction.

in all of the video i watch when it comes to fixing gadgets this northridgeFix i enjoy alot and i just subscribed this morning and i'm still watching all of your videos..lol fells like netflix on me haha

It's what you do. It's experience. That's Alex teaching for free. Thank you Alex!

In 00:06:27 there is a small resistor/capacitor located at right side of the 4C09B MOSFET which seems to be blown. Could you check it out

Inspecting boards fast as Superman? Super-Alex is born 😂😊😉

I wasting a lot of cotton bud and IPA now i learn sharpie trick. Very handy. Credit for that.

question: The initial faulty mosfet was a p channel mosfet; Is it possible that you turned it on by checking the source with positive probe and the negative probe on the gate? you might mistakenly judge that the mosfet is defective when you measure drain to source resistance since the DMM will read 0 ohms.........

Isn't there a controller IC for the Mosfets? perhaps this is an issue?

lahaulla wallakuata illabillah.... respect to mr.allex

Machalalh brother i love your work

Maybe the driver IC or replace all the vcore mosfets because they work in parallel mode. I had the same issue with a Dell. changing mosfets one at a time didn't work like in your video.

Try the Flir camera while powering on laptop ?

I really like the riddler question mark!!!

Also, who those mosfets feed?

Maybe the power IC which controls signals on gate is bad, like on olders AMD GPUs.

5:07 Alex is doing pretty well with micro-paintings too 😉

Faulty gate resistor? I mean usually they would fail towards high resistance or even open circuit, but maybe this one is just different. Maybe heating up the area caused a solder bridge underneath one of the gate resistors.

Thought the same.... 🤔🤔 Alex already had this same issue a time a go were also a member told him that idea with the gate transistor where it fails a few days after the repair 👌🔝🔝🔝 Good video as always Alex greets from Austria 🇦🇹🇦🇹

Inspect on thermal camera when turning on laptop what is happen with replaced MosFet's

Can you pop a capacitor with the heat gun once?

Maybe plug charger in and with thermal camera have a look what's getting worm first may give an idea ?

thermal camera?

Love the sharpie trick :)

I think the board should be removed from the chassis completely for an inspection and cleaning. I've seen times where some foreign object on the otherside of the board has caused me grief.. usually luck was on my side and removing the short was enough.

The lone whistle... Perfect fit

Mosfets rarely blow for no reason. Simply replacing them doesnt get rid of the reason why they shorted. Also a blown mosfet can take out components that drive them.

I love the bloopers there at the end lol

Hi, can SSD be fix? I don't want the data just can be use back

One of mosfets missing pulldown resistor, it probably stay open for too long killing others in process. And maybe more then just mosfets.

Have you ever had a Framework Labtop on the shop for repair iv seen these for ever and yet never have I seen them come into your shop. After seeing the staggering amount of Asus/HP/MSI come in for same issues I refused to buy those so I opted to wait for a nice next gen Framework with a amd cpu and dedicated GPU. Since they can later be repurposed into a tablet 😱.

Hi , fiind the controller for those mosfet and change with good know one and after that change also all mosfet in that area

Happy Eidilfitri to you sir!

Sharpie 😄at first I thought you said "car key" 😂

Does that laptop maybe have a battery lock feature? eg it wont start without main battery (also used as the bios battery), that would make troubleshooting a pain if u dont have a spare to try

Perhaps the diodes or resistors

hi, maybe a faulty regulator who controls all these MOSFETS ?

I have custom made motherboard of my laptop, and its not working and my laptop is not turning on. I have a question, if i send motherboard to you would you like to have a try to repair that? Please let me know, so i can send that to you.

Hi Alex you need always to change the controller low and high side mosfet always together by buck converter other you get such issues or issues laptop one hour work then died

Have a similar laptop with the same issue, hopefully you can find what it is causing that...

so, can somebody remind me again why we have decided to ditch socketed cpus for many laptops? i dont see how products are better off for it. I felt ripped off even when I found out my Surface Pro 5 had a cheap, somewhat slow emmc surface mount ssd. So when that thing runs out of good block my whole device is cooked, or i have to send it to Northridge Repair? Whats up with that/

Disconnect coils from CPU and put new mosfets and try it with disconnected coils while monitor with oscilloscope for waveform. I had similar problem, when i measure mosfet and he look ok until start working, then he make short to ground.

The last scene was like BEHIND THE SCENE

Hi! I try to leatn english, what do you say after 24,50?)

go with your gut alex CPU ...YOU ARE THE TRUSTED ONE ....

You should create a channel for the boss of all bosses in real time, maybe without sound (or chilling music so we just can watch him disassemble and assemble all the different devices, because that would also be a big inspiration to people, and besides that you can use it for proof if a customer complaints telling you that you destroyed something in the device. Even though i have alot of experience myself i would definitely watch it 🙂

Its similar to pre obd vehicles blink their service engine light to tell you the error codes. code 1 and code 12 is what i saw

Here's a rhyme they ought to sing for their newest commercial: *ASUS Products* 🎵You fix one component, then two go bad. Don't fix OUR products, BUY new ones instead.🎵

Maybe the charger is causing the problem? you could try with just the battery?

Every time I've seen this issue its been in the fet controller circuit. without a schismatic its almost impossible to pinpoint. good luck

good trick, was using tape to see the markings.

Thanks

Very strange, i think that the microcontroler is faulty ?

Why didnt you messure the caps? Maybe one is faulty and causing the problem.

my asus strix is only 2-3 years old, and after the first year the battery stopped holding a charge and only worked while plugged in... recently, i went a month without using it, and now it wont power on and the power light doesn't turn on i removed battery, reseated the ram and hd, nothing working tomorrow i will check the charging port and other components with my multi meter. ive only used my multimeter once, so i'm not sure what settings or what points to connect i really can't afford a new laptop 😢

I am not expert but I have been watching your videos for a while. may be those MOSFETS are in parallel mode and need to be replaced together with same type as in one of your previous video

I don't know if you've revealed this, but do you give the owners of dead boards any small rebate back. You get quite some benefit with all those spare parts, so a little cash back sounds equitable. Maybe $15 if you're generous? Thanks.

Reminds me of that MSI laptop where the mosfets work in pair

Nice end.

I have same using from 6 years this is good hardware

Considering you Laptop Model, Do a Jumper reset by metal tweezer by shorting the 1st and the 4th Pin.

I am a collector of old laptops and phones. Old Asus laptops are reliable until DDR1, Dell and HP NEVER were. I also have a lot of Toshiba and Fujitsu laptops that are not easily fixable, from the 90s.

Asus vivobook 14 i3 11th generation is not getting on and after eject its nvme it is getting on, please give me advice to fix this problem....
