Troubleshooting an External Keyboard
or External Keypad
During POST, the computer checks to see if an external
keyboard or keypad is connected. If an external keyboard
is connected, the computer recognizes both the built-in
and the external keyboards. If an external keypad is con-
nected, the computer recognizes the external keypad and
the built-in keyboard, but does not recognize the embed-
ded numeric keypad. If an attached external keyboard or
keypad does not work when you boot the computer, make a
copy of the Diagnostics Checklist found in Chapter 5 and fill
it out as you complete the following procedure.
NOTES: If you use a PS/2 “Y” adapter to connect an
external device to the computer’s PS/2 connector, the
device does not work.
Before you begin this procedure, make sure that the
SYS-
TEM SWITCH
option in the System Setup program is set to
ON/OFF
. For instructions, see “Using the System Setup Pro-
gram” in Chapter 2.
1.
Make sure the cable from the external keyboard
or keypad is firmly connected to the external key-
board/keypad/mouse connector on the back of the
computer. (See “Checking Connections” found
earlier in this chapter.)
2.
If you are using a keyboard with various switch
settings, make sure the switch is set to “PS/2,”
“Enhanced XT/AT,” or “PC/AT.”
The switch settings are usually on the bottom of the
keyboard, sometimes behind a panel tab.
