A friend has a laptop Compaq Contura 410CX, which, she says, she switched off in an "abnormal" way. Apparently you're meant to switch it off using Ctrl-Alt and the power button. She just held down Ctrl-Alt and it switched off and now won't switch on again.
The only light that comes on is the "Battery Charging" light. Pressing or holding down the power button does nothing. No noise is heard at all. The "Battery Charging" light goes out until I let go of the power switch. I've tried pressing all sorts of other buttons in different combinations. Does anyone know better?
