How to Run the Keyboard Test:
Use the
following procedure to run the keyboard key test.
1. Power-off the computer.
2. Remove the external keyboard, if one is attached.
3. Press and hold F1 key, then power-on the computer.
Hold F1 until the Easy-Setup screen appears.
4. Select Test and press Enter. The basic diagnostic
screen appears.
5. Press Ctrl
+
A (to go to advanced diagnostic screen).
6. Press Ctrl
+
K (a keyboard picture appears on the
screen).
7. By pressing a key, the mark appears or disappears
on the corresponding key position on the screen.
Repeat this step for any keys that need to be tested.
8. To exit the test, press Esc or select the cancel icon.
PC Test Card LED:
The green LED on the PC test
card lights when the PCMCIA test is running. If the LED
does not go on, check that the card is installed correctly by
reseating the card. If it still does not light after reseating,
try using another slot for the test. If the LED still does not
go on and the test fails, replace the FRU shown in the
diagnostic error code.
Errors During the POST:
If the POST detects an
error, a three- to eight-digit error code is displayed.
Memory Errors:
If the POST detects a memory error
in the first 640KB of system memory, all of the first bank
memory is de-allocated and the test continues with the
second 640KB of the second bank memory. If the total
amount of error free memory becomes less than 2MB, a
2XX POST error occurs and the system stops. All of the
remaining memory is used as system memory. When the
POST memory test has completed, the usable memory
size is compared with the configuration data and if a
mismatch is detected, a 2XX error code occurs. The user
can continue with system operation by pressing Esc, and
F1 after restart and call for service at a later time.
The memory sizes that are de-allocated because of the
POST process is kept by the hibernation or suspend
functions. To test this memory, it must be re-configured as
part of the original memory size. The memory
re-configuring is done by turning power off and on.
De-allocation support is done only by the POST for
memory errors. All unrecoverable memory errors that
occur during normal operation cause an interrupt to the
operating system.
