i dropped my aspire one yesterday, it fell about 3 inches onto a wooden table and landed on its corner while in standby mode. now it starts up fine but then turns off with no warning after 1-2 minutes. the battery is fully charged, and it does this whether it is plugged in or not, and the battery is fully charged. this usually means that it turns off within seconds of getting to a windows desktop, but it did a checkdisk once and turned off in the middle of that too, so i know it's not something in windows. the only cause i can think of is that the heatsink got disturbed when i dropped it, but is 1m enough time for an atom processor to overheat? can anybody think of any other reasons that it might be doing this? also, if i pull it apart to see if i can fix it, do i lose my warranty?
