Laptop shuts itself down
My thinkpad a20m automaticly turns itself off. The time its on for before shutting down varies. The fan goes on at startup but once booted into windows i have not seen it spin. Once it turns off by itself i have to unplug power and battery then plug in again to turn on. I would have thought overheating except that i dont see my fan go on while booted into windows and the fact that i have to unplug and replug power to be able to turn on. I also would have thought maybe its a broken fan, but it does go on right when i turn it on and stop once windows has started to load. Any ideas whats wrong?
Thanx
