Keyboard Problems
The screen displays a keyboard error message when you
turn on or reset the computer.
Make sure the keyboard is securely connected to the keyboard
port and not the mouse port. Although these ports look alike,
they cannot be used interchangeably.
Nothing happens when you type on the keyboard.
The Lockout Timer may be set in SETUP. This option
disables the keyboard for a specified period of time after the
system returns to an active mode from a low-power standby
mode. This delay gives Energy Star compliant monitors the
time they need to return to an active mode. Wait a few seconds
and try again.
See ‘The Computer Does Not Respond,” above.
The cursor keys on the numeric keypad do not work
properly.
If the Num Lock light in the upper right corner of the keyboard
is lit, press Num Lock to turn off the function.
