The power distribution board is beside the power supply and serves to separate
the power produced by the power supply into the voltages needed by the
various internal components.
To replace the power distribution board:
1 Turn off the system and disconnect the power cord and external
peripherals.
2 Open the case. (See “Opening the case” on page 18 and “Preventing static
electricity discharge” on page 17.)
3 Remove the power supply as described in “Replacing the power supply”
on page 51.
4 Unplug the cables that connect the power distribution board to other
system components. Note the location and orientation of each cable
before you remove it.
5 Remove the four screws that secure the board to the chassis, then remove
the power distribution board.
