CAUTION: Avoid bending the protrusions in the CPU socket. This mishandling can damage the CPU
socket.
NOTE: Store the processor in a safe place where it will not be damaged.
To replace the processor:
1. Disconnect power from the system (
Predisassembly procedures on page 57), remove the side
access panel (
Side access panel on page 62), the CPU heatsink (CPU heatsink on page 95), and
the processor (
Processor on page 97).
2. Raise the processor socket handle fully (the full swing angle of the lever is approximately 90
degrees).
CAUTION: Processor pins are delicate and bend easily. Use extreme care when placing the
processor in the socket to avoid bending pins.
3. Align the triangle on the top of the processor with the triangle on the corner of the processor socket
and install the processor into the socket. Ensure that the underside of the processor is level with
the top of the processor socket. Lightly press down on the top of the processor while closing the
socket lever.
