70 Replacing and Adding Internal Devices
Replacing the PS/2 power supply
The PS/2 power supply does not support fault tolerance or hot-swapping. If
the power supply fails, you must replace it.

To replace the PS/2 power supply:

1Turn off the system and disconnect the power cord and all peripherals.
2Open the case. (See Opening the case on page 23 and Preventing static
electricity discharge on page 22.)
3Disconnect the power supply connectors from all internal devices,
including the 3.5-inch diskette drive, the CD drive, and all hard drives.
4Disconnect the main power supply connector to the system board, by
pressing on the tab to release the connector, then gently pull the
connector from the board.
5While supporting the power supply with one hand, remove the screws
securing the power supply to the back panel and the top panel.
