fully functional.

HECK THE KEYBOARD CABLE — Shut down the computer, disconnect the
keyboard cable and check it for damage, then firmly reconnect the cable.
If you are using a keyboard extension cable, disconnect it and connect the
keyboard directly to the computer.
CHECK THE EXTERNAL KEYBOARD —
1 Shut down the computer, wait 1 minute, and then turn it on again.
2 Verify that the numbers, capitals, and scroll lock lights on the keyboard
blink during the boot routine.
3 From the Windows desktop, click Start → All Programs →
Accessories → Notepad .
4 Type some characters on the external keyboard and verify that they appear
on the display.
If you cannot verify these steps, you may have a defective external keyboard.
TO VERIFY THAT THE PROBLEM IS WITH THE EXTERNAL KEYBOARD, CHECK THE
INTEGRATED KEYBOARD —
1 Shut down the computer.
2 Disconnect the external keyboard.
3 Turn on the computer.
4 From the Windows desktop, click Start → All Programs →
Accessories → Notepad .
5 Type some characters on the internal keyboard and verify that they appear
on the display.
If the characters appear now, but did not with the external keyboard, you
may have a defective external keyboard. Contact Dell
(see "Contacting
Dell
" on page 170 ).
RUN THE KEYBOARD DIAGNOSTICS TESTS — Run the PC-AT Compatible
Keyboards tests in the Dell Diagnostics (see "Dell Diagnostics" on page 107).
