4.5 LED Board
It is very unlikely that the LED board will have to be replaced.
There are two indicators in the LED board: HDD and power. You
do not need to remove the backplane and bracket to replace the
LED board. Simply detach the bays for the FDD, HDD and slim
CD-ROM drive, and then unscrew the three screws fixed into the
panel. Before removing the LED board, carefully detach the cables
by pulling them down.
