Keyboard Does Not Work
If the NumLock indicator in the upper right corner of the keyboard does not
light when the system powers up, or the keyboard does not work:
Check that the keyboard cable is securely attached to the system unit’s
keyboard connector.
If possible, substitute another keyboard that is in good working order. If the
substitute works, your keyboard may need replacement.

If your mouse pointer does not move or moves erratically when you move
the mouse:
Check that the mouse cable is securely attached to the mouse connector on
the system unit.
Disassemble the mouse and clean the roller ball. (This does not apply if you
have an optical mouse.)
