Processor
For a list of available processors, see Processors and memory modules on page 13.
1. Prepare the computer for disassembly (see Preparation for disassembly on page 23).
2. Remove the rear port cover (see Removing the rear port cover on page 23).
3. Remove the stand (see Stands on page 24).
4. Remove the access panel (see Access panel on page 25).
5. Remove the heat sink (see Heat sink on page 41).
6. Rotate the locking lever to its full open position (1).
7. Raise and rotate the microprocessor retainer to its fully open position (2), and then carefully lift the
processor from the socket (3).
IMPORTANT: Do not touch the pins in the processor socket. These pins are very fragile and handling
them could cause irreparable damage. Damaged pins might require that you replace the system board.
The heat sink must be installed within 24 hours of installing the processor to prevent damage to the
processor’s solder connections.
NOTE: After installing a new processor onto the system board, always update the system ROM to ensure
that the latest version of the BIOS is being used on the computer. The latest system BIOS can be found on the
Web at: http://www.hp.com.
