PC Test Card LED
The green LED on the PC test card turns on when the
PCMCIA test is running. If the LED does not turn on,
check that the card is installed correctly by reseating the
card. If it still does not turn on after it 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.
