7 Gently lift the heat sink off of the processor and set the heat sink aside
upside down (thermal grease side facing up).
CAUTION: The processor is held in its socket under strong pressure. Be aware
that the release lever can spring up suddenly if not firmly grasped.
8 Position your thumb firmly over the processor socket-release lever and
release the lever from the locked position. Rotate the lever 90 degrees
upward until the processor is released from the socket. See Figure 3-20.
9 Rotate the processor shield upward and out of the way. See Figure 3-20.
10 Lift the processor out of the socket and leave the release lever up so that
the socket is ready for the new processor.
CAUTION: Be careful not to bend any of the pins on the ZIF socket when removing
the processor. Bending the pins can permanently damage the system board.
If you are permanently removing a processor from socket CPU2, you must
install a processor blank and a heat-sink blank to ensure proper system
cooling. Adding the blanks is similar to adding a processor. See "Installing a
Processor."
NOTE: In single-processor configurations, a processor must be installed in socket
CPU1. Install the blanks in socket CPU2 only.
