PC Card (PCMCIA) Slots Test
The green LED on the PC test card (P/N 35G4703) turns
on when the PC Card (PCMCIA) slot test is running. If the
LED does not turn on, check that the card is installed
correctly by reseating it. If the LED still does not turn on
after the card is reseated, try using another slot for the
test. If the LED still does not turn on and the test fails,
replace the FRU shown by the diagnostic error code.
Universal Serial Bus (USB) Test
At the advanced diagnostic test menu, connect the USB
parallel test cable (P/N 05K2580) to the computer. Click
on the USB icon to run the test. Follow the instructions on
the screen. OK appears if the test passes and three lines
of error codes appear if the test fails. The defective FRU
must be the DC/DC card or the system board.
Use cable number 2 for an external USB port on the port
replicator.
Displaying the Error Log
Diagnostic errors are printed on a printer that is attached
to the parallel port when the error is detected. The error is
also logged in the system memory.
Use the following procedures to display the errors:
1. Enter the advanced diagnostic test.
2. Press Ctrl+E.
3. The error log appears.
4. To exit the window, click on Exit or press Esc key.
The error log is not saved when the system power is
turned off.
Checking the Installed Devices List
If a device is installed but its icon appears in gray shade
rather than in dark shade on the basic diagnostics test
menu, the device is defective. Reseat the device
connectors. If the symptom remains, replace the device or
the system board. If needed, adjust the contrast control to
clearly distinguish the shades of the icon.
