NOTICE: To ensure maximum cooling for the microprocessor, do not touch the 
heat transfer areas on the microprocessor thermal-cooling assembly. The \
oils in 
your skin reduce the heat transfer capability of the thermal pads. 
3.  Remove the 
microprocessor thermal-cooling assembly. 
NOTICE: When removing the microprocessor module, pull the module straight 
up. Be careful not to bend the pins on the microprocessor module. 
4.  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. 
The ZIF-socket cam screw secures the microprocessor to the system board.\
 Take 
note of the arrow on the ZIF-socket cam screw.
5.  Use a microprocessor extraction tool to remove the microprocessor module\
. 
Replacing the Microprocessor Module 
NOTICE: Ensure that the cam lock is in the fully open position before seating 
the microprocessor module. Seating the microprocessor module properly in\
 the 
ZIF socket does not require force. 
NOTICE: A microprocessor module that is not properly seated can result in an 
intermittent connection, or permanent damage to the microprocessor and Z\
IF 
socket. 
1.  Align the pin-1 corner of the microprocessor module with the pin-1 corne\
r of the  ZIF socket, and insert the microprocessor module. 
NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns\
 
with the triangle on the pin-1 corner of the ZIF socket. 
NOTICE: You must position the microprocessor module correctly in the ZIF 
socket to avoid permanent damage to the module and the socket.

When the microprocessor module is correctly 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 correctly.
NOTICE: Hold the microprocessor down while turning the cam screw to prevent 
intermittent contact between the cam screw and microprocessor. 
2.  Tighten the ZIF socket by turning the cam screw clockwise to secure the \
 microprocessor module to the system board. 
3.  Update the BIOS using a flash BIOS update program floppy disk or CD. For\
  instructions on how to flash the BIOS, see
