I have a 3 year old HP Pavilion dv2208 laptop. Recently it started abruptly powering off in like ~20-30 seconds into Windows boot sequence after almost every reboot/shutdown. Even if I leave it in Repair/Start Windows Normally stage it powers off anyway.

The only way I managed to workaround this is to enter BIOS setup screen and leave it on for no less than 10 minutes. I don't know what happens there but this helps every time.

Any ideas of possible ways to fix this that don't include replacing motherboard are highly appreciated.

P.S.: I've tried resetting BIOS to defaults, updating to the latest BIOS version, etc. Happens with both Vista and Windows 7.

I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't… >>> More
