Access Panel on page 44).
3. Lay the computer on its side with the rear facing toward you.
4. Remove the fan sink
Fan Sink Assembly on page 71).
5. If removing an AMD processor, skip to step 6. If removing an Intel processor, rotate the locking
lever to its full open position (1), raise and rotate the microprocessor retainer to its full open
position (2), and then 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.
CAUTION: The heat sink must be installed within 24 hours of installing the processor to
prevent damage to the processor’s solder connections.
