Acer 722 laptop new motherboard powering off problems

June 28, 2013 at 06:36:40
Specs: windows 7, 2gb
I have recently fitted a new motherboard in my Acer aspire one 722. The laptop powers off abruptly after about 1 minute even if only powered to a bios screen. I removed the fan and heatsink today and noticed that the thermal compound that I applied to the cpu is not touching the heatsink atall. Could this explain the powering off and if so have I applied too little thermal compound to the cpu?

"I applied to the cpu is not touching the heatsink atall. Could this explain the powering off"

Yup, that's the problem. Find your CPU & follow the instructions exactly (you do NOT have to use Arctic Silver):

Thanks for your response. I noticed that the underside of the heatsink has no trace of the thermal compound. I think that I applied a layer of compound that was too thin.
I used arctic silver compound but have some cheaper stuff. Will try applying a thicker layer of the compound and ensure that it makes contact with the heatsink.

Do you think that I may have damaged the cpu by applying too little thermal compound? I powered it on today. it dual boots, windows 7 and android 4.0 It powered off very quickly while trying to boot windows 7, but when tested with android it stayed on for about half an hour before powering off.
