AC power on my laptop Toshiba satellite freezes and I have to forcibly off it by computer power button. and to start it on battery power now, Windows Vista will recommended start with repair option.
My computer works fine on battery power, so every time I have to shut off my computer and charge the battery in idle condition then use it for 2hrs on battery power, and again put off computer for recharging. Can any one tell me why it hangs on AC power ON, I have tried AC power adapter but problem remains. my computer using shared graphic card on motherboard.
