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

[@Djazeiry]

just an excellent electronics teacher ...amazing

[@Barbarapape]

You have excellent fault finding skills. I still prefer desktop PC's they are far eaisier to find faults unless you wish to go down to component level, most of the time it is not worth the hassle and time, time costs money.

[@DIYRepairHour]

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

[@Barbarapape]

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?

[@DIYRepairHour]

@@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.

[@DIYRepairHour]

@@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.

[@DadofScience]

I'm currently working on a Lenovo ideapad 330 and it has a short on the power rails, and like this example it's also a single integrated board. I've removed and tested one set of MOSFETs and the short remained, and none of the devices was short, so now I'm off to the next cluster of components. I was hoping to see a dead ceramic or tantalum cap, but no joy. No visible damage at all. The thermal camera looks like quite a valuable tool.

[@seidumomoh7791]

[@namdoyle]

Is that really hard to place "something" to prevent the 19v pump into vram and gpu when the high side MOSFETs shorted? Or,the factory intent to do that so people keep buying there new products.....

[@greyroo]

I guess the customer will have to be happy just playing Minesweeper and Solitaire from now on.

[@steinbauge4591]

well, you have eGPU

[@steinbauge4591]

It can still live as a gaming machine if it has either 2 nvme slots or Thunderbolt: with 2x nvme you can connect an external gpu through an eGPU adapter through one of them. Or if it has nvme and SATA. For me even a 17" laptop screen is too small for anything except very casual gaming, need external keyboard too.

[@lelescruz1100]

I have the exact same model like this one. I think its a common issue. I found 3 shorted vram that is heating up based on thermal camera. I removed 2 output coils going to gpu and the laptop is working fine now. But of course customer is only using the intel graphics. Its better than a non-working laptop. Thanks

[@TacBlades]

There must be a way to design in short circuit protection for MOSFET shorts, current limiters, or current foldback or something so when MOSFETs fail then it won't destroy other parts of the circuit. ?

[@eyadmubarak2869]

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

[@siggystroo]

but why did the VRAM get shorted...any experience on Acer Nitro 17 2023? i hear that they dont have a fuse on the power reals on the CPU and GPU.. is that true and how much is important?

[@xx3868]

Great video, but what about the hot current still going to the vram? Wont this cause a fire or burn more things out anyway even without the GPU, Can you show how to isolate the draw there so that area is dead and safe.

[@juzo4321]

I have this exact problem with the same laptop. It was repaired but the gpu is dead. How do I unsolder or remove a component from the board to disable the gpu entirely. The battery life has taken a hit losing about 45mins to 1 hour of total time because I believe the gpu chips are shorted and using lots of power. I heard you say in the video you can unsolder some components but didn't show the process. Any info is appreciated! 🙏🏽

Wait, mosfet work like fast switch and with coil reduce voltage from maybe 5v to 1v. But here this mosfet just "stuck" and no switching and all voltage go directly to gpu/vram right? Omg, why this so important component can short?

Hi. I have a acer nitro 5 with GTX 1650. And for some reason, it crashes and restart itself after high use of GPU for some seconds. I already updated the GPU driver, bios and no solution, reinstalled drivers and windows, changed the thermal. No sucess. In the windows events it shows the kernel power problem. Could it be a / electronic problem? I can't play or work using nvidia gpu anymore. Help, please :(

What if you change the vrams ? Because I have the same problem, after I was playing my legion 5 15imh05h dead. When I go to the professional technical he said I have a problem in vrams then we command a new vrams the he change the dead vrams to the news and my pc back to life!

[@ksrele]

I don't understand how FET can be shorted to ground when it doesn't even have connection to ground. FET have input voltage, gate voltage, output voltage and it acts as switch and pass input voltage to output when controlled from gate voltage.

[@andrewwturner]

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

[@fendularatsq2317]

cant you use memtest now that it can boot and see which memory is faulty? i think i saw people fix those gpu-s just by replacing faulty banks

[@DumahBrazorf]

Did you watch and understand the last 3 minutes?

[@orange11squares]

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

[@twx8626]

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

Sorin, can you make a video with some ideas for protecting against this type of failure on a working gaming laptop. I know this sounds crazy but if anyone can come up with a dodgy addon i know its you!

[@hbh3144]

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?

you say when it’s shorted al the power going trough all those chips. Why don’t they limit it with a fuse or…? There are so much gaming laptops dead because of it.

[@jxmai7687]

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

[@yellouu_theree]

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

Hi! I have an ASUS Zenbook 13 UX331UN which works with the charger and shows 100% battery but it is very slow and when I unplug it, it immediately turns off, I think it is a charging circuit because at the battery connector on the motherboard has low voltage.

[@dazzle4416]

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.

[@itnaklipse1669]

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

[@JOEGAMESLAB]

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

[@DenjiW]

That VRAM chip was dead anyway, so it would still be worth removing it to prove the point. If something else really does get hot, the point would be proven that the GPU chip is dead. But if nothing happens then the short went only as far as the VRAM chip. You know, I absolutely love your videos, but it seems to me that you simply didn't want to reball a replacement chip, which is understandable and it would be best to just address it like it is.

[@ThermalWorld_]

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 😄

[@marksutherland774]

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..
