CAUTION:
Before you begin any of the procedures in this section, follow the
safety instructions located in the Product Information Guide.
NOTICE:
To prevent static damage to components inside your computer, discharge
static electricity from your body before you touch any of your computer’s electronic
components. You can do so by touching an unpainted metal surface on the
computer chassis.
Replacing the Power Supply
1 Follow the procedures in "Before You Begin" on page 99.
2 Remove the computer cover (see "Removing the Computer Cover" on
page 101).
3 Remove the support bracket (see "Removing the Support Bracket" on
page 102).
4 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.
5 Remove the optical drive (see "Removing an Optical Drive" on page 140).
6 Remove the hard drive power cable, optical drive data and power cable,
front panel cable, and any other cables from the securing clip on the side
of the power supply.

computer chassis.
