Fujitsu Lifebook T4020D Overheating

Hi,

I'm having overheating issues with my T4020D Overheating (freezing, suddenly shutting off, very hot etc..) the fan still works and I have opened up the laptop and cleaned out all the dust and replaced the thermal paste with Arctic Silver 5 but still it overheats and I'm not sure of anything else I can do any help would be greatly appreciated.

 

Are you sure the fan is spinning.
If it is, then it sounds more like a hardware failure in the mainboard or the cpu.

Load up a temp monitoring program like Speedfan and as soon as you are in windows start it and watch to see what the temps are doing. If they are going up, then either the fan is not coming on, your heatsink is attached wrong/crooked (or your compound was done poorly), or you have a hardware failure.

It still could be something else though, have you tested the memory?
This is why you need to make absolutely sure it is actually overheating.


If the machine is warm, odds are the heatsink is drawing the heat out of the heatsink, but not out of the notebook, this usually indicates a fan issue. If you can't tell by sound, do a cold boot on a cold system, see how long it lasts, then restart after the crash and see how far you get. You should get less and less into Windows as it heats up more and more. Beware this could hurt your system, but unlikely.

 

sorry I got caught up in some stuff and forgot about my laptop, I have tested the laptop with new ram and still the same problem and you are right about the laptop responding less and less after each reboot. I can see the fan spinning perhaps its not spinning fast enough that's all I can think of right now.

thanks for the help leslieann
