Processor Upgrade Installation Guide 1-1
You can upgrade your processor to take advantage of future options in speed and
functionality. Each processor and its associated cache memory are contained in a pin-grid
array (PGA) package that is installed in a ZIF socket on the system board.
Replacing the Processor
CAUTION: See your System Information Guide for complete information about
safety precautions, working inside the computer, and protecting against
electrostatic discharge.
CAUTION: The processor and heat sink can get very hot during normal operation.
Ensure that they have had sufficient time to cool before you touch them.
1Turn off the system and attached peripherals, and disconnect the system from the
electrical outlet.
2Press the power button to ground the system board.
3If you have installed a padlock through the padlock ring on the back panel, remove
the padlock.
4Lay the system on its side as shown in Figure 1-1.
NOTICE: Ensure that sufficient space exists to accommodate the open cover—at least 30 cm
(1 ft) of desktop space.
5Open the system by pushing the buttons on both ends and lifting the cover open.
See Figure 1-1.

NOTICE: Be careful not to bend any of the pins when you remove the processor from
the socket. Bending the pins can permanently damage the processor.

position so that the socket is ready for the new processor.
10 Align pin 1 (the imprinted corner) of the processor and pin 1 of the socket.

properly with the socket, and do not use excessive force when you install the processor.
11 Carefully set the processor in the socket and press it down lightly to seat it.
12 Rotate the release lever back toward the system board until it snaps into place,
securing the processor.
