CAUTION: Heat sink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly seat the heat sink to the processor. This is especially important as the pins on the socket are very fragile and any damage to them may require replacing the system board. When reinstalling an existing heat sink, make sure that its bottom has been cleaned with an alcohol wipe and fresh thermal grease has been applied to the top of the processor. New heatsinks come from the factory with fresh thermal grease already applied. Processor 1. Prepare the computer for disassembly (Preparation for Disassembly on page 25). 2. Remove the access panel (Access Panel on page 26). 3. Lay the computer on its side with the rear facing toward you. 4. Disconnect the heatsink control cable from the system board and remove the heatsink Heat sink assembly on page 56). 5. Rotate the locking lever to its full open position (1). 6. Carefully lift the processor from the socket (2). 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. CAUTION: The heatsink must be installed within 24 hours of installing the processor to prevent damage to the processor's solder connections. Processor 57
