Acer Nitro5 not powering on, not charging motherboard repair, 3060 GPU died because of a Mosfet

[@duplicitousdemocracy2246]

Increasingly, the UK is not a good place to live. The cost of living crisis, corrupt government and opposition, burgeoning authoritarianism, I could go on and on. One of the few good things that if we have is the ability to send our electronic repairs to Sorin. Your integrity, honesty and kindness towards those that need your help is off the scale. Thank you Sorin for restoring my faith and being someone I can get help from if and when I need it.

[@justinspiredfallout]

I was having a nice day until you reminded me about life in the UK. 🤣

But you can't deny the GBP is pretty strong. Said out of the perspective of a third-world country.

[@duplicitousdemocracy2246]

Of course there are elements that are advantageous but increasingly we are suffering ridiculous price increases, official inflation rate is 10% but in the real world is much higher. Younger people, even with a decent job are unable to buy their own home. Having said all this, I do appreciate that some people are far less fortunate than us. Romania's loss but we have Sorin, who has already repaired my friends smart phone at a very reasonable and affordable price. @@madcat4563

Hi Sorin, please give us all an update sometime on your RPM graph. I have removed AdBlock and been watching adverts all the way through on yours and others channels, as I'm sure many others will have been doing too, it would be nice to know that you are seeing some benefit. A bit like a game, if we the content watchers can see the graph go up for you it will positively reinforce our behaviour to make the graph keep rising (I hope). I don't know about anyone else, but I could sense a real positivity about you on this video, long may it continue ;-)

Same here! I hope my little contribution will help the channel.

I use a stand with 2 big fans blowing air on the bottom of the laptop. So far my rtx3050 laptop is still working after 1 year.

[@brandonwoodford579]

Excellent repair. I know this is a stupid question but, how come the mosfets started to bubble up while you soldering them back on with hot air? Obviously hot air, but I just have never seen. Is this common?

[@justinspiredfallout]

It's the flux paste. It liquifies and starts boiling at a high enough temperature. Perfectly normal.

[@sekyiemmanuel3059]

And also good morning from Ghana Keep up the great work and also teaching us

[@electronicsrepairschool]

Thank you, I will

[@obvious7777]

i had a similar issue with my laptop, but luckily it had a GPU board that was separate from the motherboard, and allowed for easy replacement.

[@TechTroppy]

Mxm GPU I believe? Sadly they don't use that anymore

[@einfelder8262]

In Australia, the expensive laptop is still covered by warranty if it fails one week past manufacturer's claimed warranty end. Acer cannot wiggle out of replacing the board in a case like this one, because it is reasonable to expect that a premium item will last beyond a set time. For such a laptop the consumer would have a case for repair even at 5 years. Not sure about Acer, but Lenovo, Dell, and maybe others re-manufacture such boards for warranty replacement purposes, so the cost to them is virtually zero. It's probably a wise investment for owners of such expensive laptops to take an extended service agreement for small money in a country which doesn't protect consumers very well.

I wish these educational videos popped up before i bought this piece of s. laptop it shorted itself after a year.

[@tafadzwamusekiwa659]

Hello Sorin, that is not a GPU core problem, its highly a vram problem, you can try using nvidia mods 455 for this 30 series card pinpoint the faulty vram, reflow if pads broken or replace if chip is dead. The power of community..... lets fix this acer.... sometime error 43 is triggered by a bad gpu bios

[@cilibriel]

Sometimes , but this is unfixable 100% . All of the vram is dead.

[@kriswillems5661]

I think your ads are back. I saw lots of them. It's strange that the GPU is still detected. I would expect it to just disappear.

[@erolnigdelioglu7195]

İt is looks because gpu is still good but vram is bad

[@chumatez]

Nice one

Mosphire you replace 1st was burned during the soldering you can easily watch it 😜

[@asv5769]

Sorin, do,you still use CH 341 programmer for Bios?

[@_Heller_]

What is the reason of short circuit of mosfet? High temp or any other?

[@Krolik314]

Why don't they use some sort of protection before or after these mosfets? Is it because they don't care?

[@brainoverload6288]

Could someone offer a quick explanation on how he knew it was most likely a mosfet on the CPU or GPU based on the low resistance on the current resistor. It would really be appreciated as I'm trying to learn.

[@karolkrasinski8947]

On modern laptops both GPU and CPU naturally have a low resistance. CPU resistance is typically around 2 - 10 ohm but GPU is very low from 0.2 - 2ohm. GPU vram from 50 - 150ohm. Mosfets separate CPU and GPU from the main power rail. If you look at the main power rail and it measures resistance within the typical values of CPU or GPU then most likely one of the mosfets went bad and connected CPU or GPU directly with the main power rail which is obviously very very bad.

[@brainoverload6288]

@@karolkrasinski8947 thank you that really helps

[@tyrellwreleck4226]

I don't think you can replace different gpu on this one unless you have working bios

[@kat0197]

I've got on capacitor 0.1 amp. Is this mean it's shorted? This one close to the Charging port.

[@deadgutz]

Hello i have a acer nitro 5 too and it stop turning on suddenly and i dont know what happened it isnt charging or anything and u have alot of videos about it i just want you to tell me what u think th problem is cause in my country i cant seem to find a technician that can fix it

[@NeL98.]

I have a laptop with a GPU problem. One day, when I was playing a video game, a warning window appeared saying 'GPU is outdated, please update your driver'. Then, a BSOD appeared. After the laptop restarted, my GPU was missing from the device manager. When I forced a shutdown by pressing the power button, my GPU appeared again. However, when I play a game, it bluescreens again. What the problem with the gpu?

[@brainoverload6288]

How did he know the CPU or GPU might be dead based on 8ohms on the current resistor?

[@Dohcoms]

Experience?

[@brainoverload6288]

@@Dohcoms Experience is quite an obvious answer. I mean how does a low resistance on the current resistor correlate to a dead CPU or GPU. I was looking for an explanation

[@Dohcoms]

@@brainoverload6288 i am still learning myself, we will just have to keep watching and practising i think,

[@cjdeleon9146]

It's due to the fact that GPU and CPU have low resistance... Normally if one of these get burnt their resistance increases... And as of Sorin finding out which one's bad is through experience... In my experience too as a tech it's also a symptom of a faulty chip or mosfet...

[@Dohcoms]

@@cjdeleon9146I think that is getting to be a common fault, A laptop cooler is vital on a gaming laptop especially but does extend the life of most laptops also...

[@renter84]

Well, I still think for a 3060 its still worth to try to replace the glowing vram chips. The customer will take the expenses probably.

[@rafak9177]

The probability of GPU/memory controller being damaged is high, but I also think he should have run Mats to see if he gets errors on all memory banks, or just one or two. It would be a good confirmation I think .

[@mikimouse3001]

Great repair skills but im dissapointed about the reliability of these machines. Having to service an expensive laptop after a month of usage makes me think that the technology isnt there yet, or maybe theyre using poor quality parts. Its not even about planned obsolescence anymore..

[@yeahright9014]

It's not "a month of usage". It's a month after the laptop's warranty expired. Assuming Acer, it's one-year warranty on hardware.

[@mikimouse3001]

my bad then, but it's still an awfully short amount of time if you ask me@@yeahright9014

You can reflow the memory.
