Dead Acer Nitro 5 get a second chance - How to disable the NVIDIA graphics 

I do exactly that, but as a hobby, not a business. That way its always woth it 🙂

I have worked all my life since the 70's in electronic repairs. Despite all the advances, i still see the same faults, often due to sub standard components. They don't want gear to be reliable or you won't buy another one. @@DIYRepairHour

@@DIYRepairHour is repairing electronics fun?..i dont know about..voltage..amps..shorted..multimeter...ground....i still enjoy this guy's videos...i want to start repairing small electronics..can u share ur experience..is it still worth the time..if its not repaired?

@@spongebob1679 my opinion? any amount of time you spend learning new things is worth it. Not only it is good for your brain, but also gives a lot of satisfaction and occasional dopamine hit. Sorin may not be the best example of dopamine hit, he seems very calm and introvert, but people are occasonally screaming on videos when the device suddenly comes to life. I sometimes dance when device "wakes up" LOL 🙂 My Mate Vince for example has pretty visible dopamine hit on his videos. I'm 45 and my goal is to learn English, and then Spanish (will start in 2 years). During covid I started learning electronics, now I have a half-decent space with tools and even upload a video from time to time. It also became my gate to get to know many people, as my daily job is software development (no contact with people outside my team). And above all it is nice to see people happy when I return their device working - some just can't hide their emotions if the device was important to them.

@@spongebob1679 as for when device is not repaired - I get the feeling as if I failed. But this is a thing - whenever you trying to learn a new skill you will fail. Let's look at sports - you will loose to someone almost every time. But eventually you will win. And you stick to that thought, that keeps you going. With electronics is much easier, and harder at the same time. Easier - because you have community you can ask for help. And you will get help, the repair community is great. Also there is a set limit - either you have no parts or device is not repairable, so you won't automatically blame yourself. Harder - beause from time to time when you deem device not repairable, you will doubt if that is really the case. But it is more-or-less the same as learning any new skill.

He did a video on that not long ago. Why don't you look it up on his channel?

replace superIO.... been there, done that....

well, you have eGPU

he mentioned it at 8:40

He removed the shorted mosfet, the vram isn't receiving any current anymore

indeed bro, i lost legion laptop that cost me around 2200 dollar and didn't last 2.5 years, because the short circuit destroyed the laptop GPU RTX 3070, it is really stupid manufacture not providing the protection you have suggested

Did you watch and understand the last 3 minutes?

memtest is vor normal RAM not for video RAM. Video RAM is seen only by the GPU.

There is a huge difference if the processor and the memory suffered a 19V electric shock instead of 1+V for the 2V GPU memory... if Musfat shorted everything around with it, memory controller, power controller and more!!!! Only in situations where there is no image short, GPU disappeared on a memory message is it possible to replace memories. Even in this case you have to replace them all. A computer over 4 years old is considered old. To replace a huge amount of components, the cost of such a repair is very expensive and unprofitable. Because you also have to give responsibility to the customer

it would.

You csn remove the inductors that delivers power to the gpu

@@sayadiyeojhenries.815 can i know which inductors which deliver the power to the GPU?

@@sebastianleonardo1933 you can check the schematics for that but usually it is the power supply near the gpu die you could also check another variant of the same laptop with no gpu and see where are the missing components

here we had a nice acer laptop, now its an oversized chrome book.

It is in the descirption. There is amazon link with all the tools he uses

The FET was shorted between drain and source. The blown vRAM (etc) completed the path to gnd.

no if you use external graphics 😂

​@@maklogetrich2378yeah you right but then you need power supply and you can't go outside with gpu on your laptop

Gamingn't

@@AlexAlex-bh8fi just look for power outlet lol

Replace the ram chips.

if the laptop is 2+ years old the battery is gone and you can check with other charger too .

check for 2nd mosfet and try change the battery too

@@maklogetrich2378 Ok, I will try to source a new battery. How do I trace the second mosfet and what do I do with it when I find it?

@@Nikhar-Ray it's usually near the charging port and check between gate and source, shorted or not

@@maklogetrich2378 OK, if it is shorted do I just replace it with a new one? If it is not shorted, then what do I do (asking because I'm not at home right now)

That would be interesting as I was thinking the same watching those "nothing could be done" videos. Some minor fault should not kill everything. Just quick googling it suggests using zener diode or similar device to protect against overvoltage. Turns out fastest "zener diode" you can buy is the GPU/CPU/RAM itself :) So that's a dead end. So may be this fault is not that minor after all. It appears mosfet in this application is comparable to dam keeping away all the water on one side. For gaming laptops that dam is huge. If it goes nothing stands a chance downstream. Running away is not an option as it simply too fast when fails. So how we deal with that? Build them as tough as we can then monitor, protect and maintain. Evacuate/rebuild when it develops a crack. It does not look like this strategy is used for mosfets. Tough - no. We want them as small and efficient as possible because laptop must be small and battery life is a thing. Monitor - no. That's an interesting topic on itself. Protect/maintain - somewhat. Adding thermal pad and keeping all those capacitors 😀helps a bit as the water is more calm and not battering it. Rebuild - no. But you could replace all mosfets yearly together with thermal paste 😀. So perhaps many dams in series with water level lower after each of it? If one fails others will keep it. Just a bit more water will pass through? But that would require a lot of dams. For speed and efficiency CPU/GPU use low voltage with low tolerance. On other side there is considerably higher voltage because we want long and thin cables with flimsy connectors. And it's the mosfet that stands in between this conflict. Let's say to get 1V tolerance it would require some 20 mosfets in series. All of them pass current so will heat up 20 times more. So goes the battery life and all the efficiency. Not to mention there is no space for them. Adding mosfets in parallel shares the load reducing stress but also increase the probability of failure as now there are more of them. So likely there is some constant how many should be in parallel so it actually reduce not increase the risk. That's already done. Some even can be switched off when there is no need for power. I may be wrong since I'm no expert on this. Just some thoughts in the wild. Other ideas?

Fuse has not much use in the notebook as their protection circuit activated before the fuse burn.

As he said . Fuse is pretty slow protection. If tvs diodes are not fast enough nothing is..

If 19v went on data lines it game over . Those data lines connect gpu chip with memory chips so figure the rest.

Would be nice if be proved the point by removing that one memory chip but i belive he had to many failed attempts and he know how it typically plays out

I definitely understand that, but 'customer' have different meanings for everyone, this was not a laptop send for repair but for a chipset replacement, the 'customer' in this case is skilled guy/computer shop

Looks like you are thinking like anyone thinks when they see the short on thermal camera 😄 You have to understand the power lines first then make assumptions.. That line goes 19V after short, on all Vram and then goes into ground.. that GPU is fulminated not just dead 😄

and did you pay attention at the end when the GPU chip was hot ?

In an old computer, replacement VRAM X6. + 2 mospat. + GPU + electrical controller VRAM. Working time and cost of parts. Don't forget you also have to give a warranty for the repair.

@@ThermalWorld_ He is right, though it is rare it could only be one vram chip shorted straight to ground. If its shorted straight to ground the gpu and the other ram modules are fine. Same as desktop gpu.

@@mreaper2265 There are cases when the shorted Vram protect all other VRAM acting like a wire, in that case it's better to remove completely the chips just to be sure about the gpu.. repair cost can go up very fast you have to reball test again, if that doesn't work, try to check again with thermal camera, see if the GPU is shorted.. You need a lot of work to do..

quite right more or less all these repair channels are fixing gaming laptops. ASUS are the most common to die but seeing this with lenovo. possibly cheap components being used to manufacture the board, there not worth the money they cost, and some cost more than a descent desktop build, at least in most cases desktop parts can be replaced without buying an entire system.

maybe people like to game on the go? what's it to you what people buy? obviously for reasons of their own.

When buying a gaming laptop, always specify that you insist on an external Nvidia graphics. You can change it in seconds just like rams.

not that simple logic, also lots dead GPU kill the Vram as in this case.

@@jxmai7687 oh yeah! You nailed it!
