CAUTION: Only a certified service technician is authorized to remove the
computer cover and access any of the components inside the computer. See the
safety instructions for complete information about safety precautions, working
inside your computer, and protecting against electrostatic discharge.
CAUTION: Before touching anything inside your computer, ground yourself by

pins. When connecting cables, ensure that the connectors and ports are correctly
oriented and aligned.
CAUTION: To disconnect a network cable, first unplug the cable from your
computer and then unplug the cable from the network device.
CAUTION: Press and eject any installed card from the 8-in-1 Media Card Reader.

1 To loosen the ZIF socket, use a small, flat-blade screwdriver and rotate the
ZIF-socket cam screw counterclockwise until it comes to the cam stop.
CAUTION: To ensure maximum cooling for the processor, do not touch the heat
transfer areas on the processor thermal cooling assembly. The oils in your skin
can reduce the heat transfer capability of the thermal pads.
CAUTION: When removing the processor module, pull the module straight up.
Be careful not to bend the pins on the processor module.

Replacing the Processor
Procedure
NOTE: If you install a new processor, a new thermal cooling assembly including an
affixed thermal pad or a new thermal pad along with documentation to illustrate
proper installation is shipped.
1 Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF
socket, then insert the processor module.
NOTE: The pin-1 corner of the processor module has a triangle that aligns with the
triangle on the pin-1 corner of the ZIF socket.
When the processor module is properly seated, all four corners are aligned at the
same height. If one or more corners of the module are higher than the others, the
module is not seated properly.
CAUTION: To avoid damage to the processor, hold the screwdriver perpendicular
to the processor when turning the cam screw.
2 Tighten the ZIF socket by turning the cam screw clockwise to secure the processor
module to the system board.
