Processor
1. Prepare the computer for disassembly (Preparation for Disassembly on page 87).
2. Remove the access panel (
Access Panel on page 88).
3. Remove the heatsink (
Heatsink on page 109).
4. Raise the locking lever to its fully open position (1).
5. Raise and rotate the microprocessor retainer to its fully open position (2).
6. Carefully lift the processor from the socket (3).
CAUTION: Do NOT handle the pins in the processor socket. These pins are very fragile and
handling them could cause irreparable damage. Once pins are damaged it may be necessary to
replace the system board.
The heatsink must be installed within 24 hours of installing the processor to prevent damage to the
processor’s solder connections.
To install a new processor:
1. Place the processor in its socket and close the retainer.
2. Secure the locking lever. If reusing the existing heatsink, go to step 3. If using a new heatsink, go
to step 6.
3. If reusing the existing heatsink, clean the bottom of the heatsink with the alcohol pad provided in
the spares kit.
CAUTION: Before reinstalling the heatsink you must clean the top of the processor and the
bottom of the heatsink with an alcohol pad supplied in the spares kit. After the alcohol has
evaporated, apply thermal grease to the top of the processor from the syringe supplied in the spares
kit.
4. Apply the thermal grease provided in the spares kit to the top of the processor and install the
heatsink atop the processor.
