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?
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.
