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.

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.

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.
