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. 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. 4.
