Laptop shuts down

Specs: Windows XP
Hi all, my Toshiba Qosmio F20 shuts down while plugged into AC power. I don’t know if it is an overheating problem, battery problem , AC jack problem, AC adaptor power problem or combination of these? The AC power LED switch is on and doesn’t flicker when I play with the jack. It won’t boot with the battery removed. The battery LED is usually orange but will turn green sometimes. Shouldn’t it power up with AC power alone? The battery isn’t charging well also. Could be battery needs changing? Don’t know. Please Help. I have took the machine apart cleaned it, applied new thermal paste (Arctic Silver) to both the CPU and GPU. I am at a loss for what the problem could be.

It should power up with the ac adapter. Check it in both ac and dc and see if it what is listed on the label.

See event viewer.

Set power scheme to always on or the lowest percentage battery you can. See if you can keep it on longer. Might be that the way it determines power is somehow broken, wrong or mis-configured. There are two common ways to use power. Kind of depends on when it was made. The OS also controls that. A live cd like puppy might give you an idea if windows.

You didn't need to put more goop on the chips!!!

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
