PC Card Slots Test
The green LED on the PC test card turns on when the PC
Card 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 window, do the following:
1. Connect the USB parallel test cable to the parallel
connector of the computer.
2. Connect Connector 1 of the cable to the USB
connector of the computer.
