I own this laptop: https://compareindia.news18.com/specification/laptops/hcl-me-xite-m-2035-b/270022
Using it for 5 years, ran without any problems, until about 3 months ago, where it gradually started to overheat and often shut down quickly - right now it can barely run YouTube for a minute before it's off.
CPU temperature is around 70-75 Celsius and the GPU is about 75-80 Celsius when the browser is open with a single tab - no gaming or anything. I've checked and got it confirmed that it's not:
  • software or operating system
  • the fan/ventilation
  • thermal grease
  • poor ventilation
  • battery/charger/power issues
  • dust etc
I took it to a repair shop and they said it's probably the Nvidia graphics chip over heating, but they seem reluctant to give me a confirmation that putting money to change it will fix the issue. So I'm afraid of replacing the chip only to find that the problem is something else(maybe the CPU is "dying"...? Not 100% sure what that term means)
Thoughts?
Also, could I somehow disable the chip as a workaround? Tried messing around the BIOS, didn't find anything.

A 'dying' chip won't get hotter, it'll just stop working.
So what are your actual temps when running youtube? Generally speaking heat doesn't make things shut down anymore, it just slows them right down.
How did you check the list of things?

The actual temps are very close to what I posted, while I'm running a video on YouTube. I can feel the back of the laptop getting increasingly hot and suddenly it turns off.


I tested them by replacing, substituting etc, and the professional tested them too anyway.

So that's not the CPU/GPU overheating, they'll just throttle and it'd be above that temp, sounds more like a power supply issue to me.

As to how to fix it, it's a laptop, you don't, a shop might but not the one you've been to, they are not good.

Could the power supply issue cause the overheating? The battery/charger are perfect. And the temperature does decrease by a few degrees when I'm not running the browser, forgot to mention.

Have you cleaned out the dust from the system? Dust can clog the heatsink but wont be obvious since the fan will still spin. Looking at your laptop's internals I'd guess the dust is between the fan and the heatsink.
This is my most likely guess what the problem is.

Next would be that perhaps the mounting mechanism has loosened. After that, the thermal paste may have degraded but it wouldn't "heat up and eventually overheat" it would just instantly be too hot. Finally, the fan may not be connected or has failed. Make sure it's spinning.

I know that you've listed all of these as a possibility but these are the only real causes to a system eventually overheating.

Lastly, laptops typically run a bit on the hot side and their components are actually designed with this in mind. It's not uncommon for a laptop to run into the 80-90°C range when under load.

How do you know these things are 'perfect'?

The only 3 things that can generate reasonable amounts of heat are a CPU, GPU and the voltage convertors in the power supply system.

The CPU and GPU temps are not so hot that they will cause a problem.

Therefore the other hot thing is causing the problem.

Yes, the dust has been cleaned out thoroughly and the thermal paste and fan replaced, still no luck. Thanks for your response.

Wow, that's a real head scratcher. Laptop CPUs and GPUs are usually bare die so replacing the thermal paste should have fixed it.
That leaves the cooling fan not running fast enough or voltage regulation problems.
Check how much voltage is being put into the CPU and GPU.
HWiNFO64 is good for this. The "Summary" window should give me everything I need except the GPU voltage. You can also check to see if it's able to monitor the fan speed. That blower fan should increase speed as the temperatures climb.

If the temps are as reported then there is no cpu or gpu over heating.

Can't make sense of it...

0.9156v going to the CPU. That looks normal.

It appears that it's a power delivery issue and not the voltage controller trying to fry your CPU. When the power delivery components overheat then the regulators will shut down to protect itself. This would require experience with repairing power conversion and delivery systems in electronics. You'll probably have to contact the manufacturer or find an experienced laptop/electronics repair company to get that fixed.

It might be the heatpipe that leaked. Did you bent it accidentally while removing thermal paste?

Remove the radiators/cooling assembly and heat the cpu copper plate (of the radiator/cooler assembly) with something (a lighter) and see how long it takes to feel any heat on the radiator side. If the heatpipe is leaked then the heat transfer will be severely worse. (the heatpipe contains water in it that phase-changes liquid-gas and runs at about 1500-3000W/mK) A damaged heatpipe will only transfer heat trough conduction through the outer casing of the copper tube, and that is roughly 400W/mk, and is a lot less cross section in the thin walled copper.

Make sure the heatpipe cooler arrangement is working and is not punctured or damaged.

If the heat pipe had leaked the cpu and gpu temps would be hotter.

As I understand that is the case here. Cpu and gpu hovering 70-80 at idle and rapid raise of temp while light usage up to shudown temperature.

Sound's like bad cooling like a dead fan, or no thermal paste or loose mount, or a damaged heatpipe.

My situation is a little different, but you may find the information helpful.
My Dell XPS 8300 video card Pegatron HD5670 was dying and appeared to produce so much heat that the CPU fan was on high all the time. I thought so because I believe when the video card was in good health. the heat level must have been reasonable or the CPU fan would have worked hard since day one and Dell engineers would have not put it in the 8300 design.
I tried few things but never suspected the video card until yesterday. I removed the video card, now I use the onboard video chip, and my antique XPS 8300 works silently and the fan works really lazily. I shared my experience here.
Best,
Little i
