I got this laptop to reinstall windows xp on it because it was working too slowly. Soo after I finally made it to backup all the data, which took like million hours to get those 100GB via LAN, and formated the hard drive. Then I started with the installation itself but when coyping installation data somewhere around 80% the laptop just turned off. So i tried it a couple more times with the same result just with differing percentage. Once, it finally made it to desired 100 but then it turned off when came to that other part of the installation with that screen worshiping new version of windows. It doesn't matter if the battery is in or out, nor does the adapter connection change anything.
