Acer Aspire 5315-2768 overheating and turning off.

Hi there,

I have an overheating Aspire 5315-2768 Laptop.

Things that I have tried already.

1/
Dusted all vents and fan

2/
re-applied thermal grease to CPU

3/
Upgraded bios to 1.43

4/
Put vista with all service packs and updates back on the system.

5/
Installed eFramwork and ePower from acer website

6/
It sits on a cooling pad

7/
Place rubber bumpers on the bottom of the laptop so that if it sits on a flat surface its not too close to the surface.

8/
Place rubber bumpers on the cooling pad so that there is space between the pad and the unit. (I also tried without the bumpers)

After all the above when I run speedfan this notebook runs at 80+ C while Idle. If I do any mediocre thing it moves to 90+ C and up and up until it shuts itself off.

The fan is constantly on because the thing is running so hot, but even that does not make a difference. I've never seen behavior like this before.

Anyone has any Ideas?

 

Use RealTemp of CoreTemp too verify the temperature.
SpeedFan doesn't play well with notebooks.

 

I also have aida64 installed, and will now install CoreTemp and give it a whirl and report back.

 

I've installed CoreTemp and it's giving the same Temp reading as speed fan and aida64. 80+ Celcius at startup and when I do any task shoots up into 90+

 

Assuming that the fan is working, thermal compound is applied and CPU and radiator make contact there is one- remote- possibility that comes to mind.
Heat-pipe that transfers the heat from the CPU to the radiator is not empty. It contains liquid that vapors and then condenses. If a heat-pipe breaks or bends too much cracks may appear and at this point the whole vapor/condense agent leaks out and heat-pipe simply stops working.

You might want to inspect it looking for any cracks.

 

Hmmm good thought! Yes the fan is working perfectly. I will inspect the copper heat rod. By Radiator do you mean the thing at the back with the fins that the fan blows through to cool the whole device?

Thanks.

 

That's what I should have meant by "radiator" but in this case I meant the part that makes contact with a CPU- assuming id does make contact.
Just make sure that it indeed makes contact with the CPU- if it does than the only thing that comes to mind the fault in the heat-pipe itself.
Such a fault is very rare but I've seen that happen so it can't be simply ruled out.

 

Hi again.

You were bang on. The heatsink itself was bad. Did not know that a lump of metal & copper could go bad. I was able to take a heatsink from another aspire 5315 and test it with this one, and the start up temperature is something like 49C and when doing lots of stuff goes up to about 55C. And that's without the cooling pad.

Thanks again.

 

I'm glad to have helped.
It's rare that heat-pipes fail but it happens especially if notebook had been dismantled.
