OK, so my aspire one wont stay turned on for more than about a minute-a minute and a half. I tried pluggin it in, i tried plugging it in and removing the battery. I know that it doesnt have to do with the Windows XP boot process because, if i open up the BIOS and leave it there, it still turns off in about a minute and a half. Is this a well- known hardware problem? what do i need to do to fix this?
