Replacing The Power Supply - Dell Vostro 400 Owner's Manual

Replacing the Power Supply

1 Follow the procedures in "Before You Begin" on page 101.
2 Remove the computer cover (see "Removing the Computer Cover" on
page 103).
3 Disconnect the DC power cables from the system board and the drives.
Note the routing of the DC power cables underneath the tabs in the
computer chassis as you remove them from the system board and drives.
You must route these cables properly when you replace them to prevent
them from being pinched or crimped.
4 Remove the hard drive cable, optical drive data cable, front panel ribbon
cable, and any other cables from the securing clip on the side of the power
supply.
5 Remove the four screws that attach the power supply to the back of the
computer chassis.
