Acer Laptop (Aspire 3000) often won't accept input and stops responding to the keyboard.
When XP stops accepting typed input, the mouse continues to function and folders open as normal, but pressing the "Close Down/Start" button has no effect and I have to wait for the battery to go flat, and then restart. If I use START/CLOSE DOWN the computer freezes.
If I call up a DOS-based GWBASIC program, the selected program functions as normal, accepting keyboard input without problems.
If I click START > RESTART the computer freezes with a non-revolving egg timer, which the mouse can still move around.
