Replacing the Power Supply
!
WARNING:
Observe proper electrostatic discharge precautions when handling
computer components. Wear a ground wrist strap on your bare skin and
connect to a ground.
The procedure assumes that you have performed a soft shutdown of the system,
removed cables and power, and removed the top cover and front panel. Refer to
Chapter 5, "Getting Inside the Computer". To replace the power supply, follow the
steps below.
1. Remove the second hard drive mounting bracket as described earlier in
this appendix.
2. Disconnect the power connectors from the system board, second hard
drive (if present), first hard disk drive, floppy disk drive, and tape drive.
3. Remove the auxiliary housing as described earlier in this appendix.
4. Using the tip of screwdriver, pull the four tabs out to release the power
supply.
The four tabs are located at the bottom of the power supply. Two in the
front and two in the back.
NOTE:
It may require some work to get all four tabs released at the same
time. It is somewhat easier to start with the two tabs at the back of
the power supply (towards the front of the chassis) and then do the
remaining tabs.
5. Lift out the power supply with the power switch still attached to the
auxiliary housing front panel.
6. Pull off the power button and remove the two screws holding the power
switch to the auxiliary housing front panel.
7. Install the power switch of the new power supply in the auxiliary housing
front panel using the same screws removed from the old power switch.
Push the power button back in place on the power switch.
8. Place the new power supply into position above the four tabs and press it
into place so that the four tabs lock.
9. Replace the auxiliary housing as described earlier in this appendix.
