USB mouse only: Make sure the mouse is firmly connected to the USB port. Try
unplugging and replugging the mouse.
Non-USB mouse only: Make sure the mouse is connected to the mouse port, not
to the keyboard port. To reconnect these two cables, turn the computer off, reconnect
the cables, and then turn the computer back on.
If the pointer doesn't move on the screen when you move the mouse, clean the mouse.

and dust.
4 Replace the mouse ball, and screw on the cover.
