Hello i have a thinkpad a22m, i recently and finally fixed the broken screen it had, it was given to me about 4 years ago by a student, i have been trying to get this laptop to work, when i turn it on, i can boot into the bios and will stay on for hours, but as soon as i make it load windows it will shut down while loading windows(it has winxp installed), also i removed the hdd tried to boot a linux live cd, and the same thing happens, while the live cd is booting the laptop shutsdown, i am stumped as to why its doing this, the cmos battery is dead, i could try replacing to see if that fixes the issue. I know the laptop is ancient but i a am fixing it as a restoration\collection project.
