Keyboard Test for the internal keyboard. See “Running
the Diagnostics” on page 33 for details.
Note: When the Fn key is pressed, a black square briefly
appears.
If the Keyboard Test detects a keyboard problem, do the
following one at a time to correct the problem. Do not
replace a nondefective FRU:
Replace the flexible keyboard cable.
Replace the keyboard.
Replace the system board.
The following auxiliary input devices are supported for this
computer:
Numeric keypad
Mouse (PS/2 compatible)
External keyboard (with keyboard/mouse cable)
If any of these devices do not work, reseat the cable
connector and repeat the failing operation.
If the problem does not recur, the problem may have been
in the connector. Recheck the connector.
If the problem is not corrected, replace the device and then
the system board.
Memory Checkout
EDO DIMM cards are available for increasing the memory
capacity.
Memory errors might stop system operations, show error
messages on the screen, or hang the system.
Use the following procedure to isolate memory problems.
Note: Make sure that the DIMM card is fully installed into
the connector. A loose connection can cause an
error.
See “Running the Diagnostics” on page 33 for details.
1. Power off the computer and remove the DIMM card
from its slot (if installed).
