I have a notebook that has a peculiar problem:
When I turn on the Notebook (HP Compaq nx8220) and and boot it (Win XP), it works fine. In case I keep the Notebook from booting properly by keeping it in BIOS or trying to install a different operating system, the Notebook turns off (instant power loss) within 30-60 seconds.
I thought the BIOS battery might be a problem so I replaced it, but it didn't work. Might anything be the issue that I can easily repair myself (meaning not having to replace the main unit)?
