cannot work. This is not a defect.
If an external numeric keypad or a mouse is connected:
1. Power off the computer.
2. Remove the external numeric keypad or the mouse.
3. Power on the computer and try using the keyboard again.
If the keyboard problem is solved, check the connection of the external

The mouse or pointing
device does not work.
Make sure that the mouse or pointing-device cable is securely connected to

work.
Change the mouse driver to Standard PS/2 Port Mouse, and then reinstall
