Replacing the processor CAUTION: HP recommends you do not swap processors (CPUs) from one motherboard to another. CAUTION: Use extreme care when installing or removing a processor. The exposed socket pins are extremely fragile. Damaged sockets will require a board replacement. Lift the processor out of the socket- do not slide the processor on the socket. When installing a processor, align the dimples on the side of the processor with the notches in the socket. 1. Disconnect power from the system (Pre-disassembly procedures on page 55). Remove the access panel (Access panel on page 63), the CPU heatsink (Removing the CPU heatsink on page 113), and the processor (Removing the processor on page 117). 2. Raise the processor socket handle fully. 3. If necessary, remove the bypass board from the socket. Align the notches in the processor base with the tabs on the socket. Seat the processor into the socket. Ensure that the underside of the processor is level with the top of the processor socket. Close the processor cover plate. Lightly press down on the processor cover plate while closing the socket lever. Figure 5-77 Seating the processor ENWW Removing and replacing components 119
