Power Supply
1.
Prepare the computer for disassembly (Section 4.2).
WARNING:
Power is continuous to the system board and power supply even when the power
switch is turned off. To prevent damage to the unit, disconnect the power cord from the power
source or the unit before beginning disassembly procedures.
2.
Lay the computer down on its large base for greater stability.
3.
Remove the access panel (Section 4.6).
4.
Disconnect all power cables from the mass storage devices and the system board.
✎
Power connectors are keyed for correct installation. Note the orientation of each
cable connector and the routing of the cables to facilitate reassembly.
5.
Remove the three external screws that secure the power supply to the back of the
chassis. The internal screw that secures the power supply to the side of the chassis may
not need to be removed, only loosened.
6.
Slide the power supply toward the front of the computer, then lift up to remove it from
the chassis.
