Secure the heatsink to the system board and system board tray with the four captive screws and attach the heatsink control cable to the system board. CAUTION: Heatsink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly seat the heatsink on 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. 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://h18000.www1.hp.com/support/files. Speaker 1. Prepare the computer for disassembly (Preparation for Disassembly on page 110). 2.
