Removing the Microprocessor Module 
 CAUTION: Before performing the following procedures, read the safety 
instructions in your System Information Guide.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist 
grounding strap or by periodically touching an unpainted metal surface (\
such as 
the back panel) on the computer. 
NOTICE: Do not touch the processor die. Press and hold the microprocessor 
down on the substrate on which the die is mounted while turning the cam \
screw 
to prevent intermittent contact between the cam screw and microprocessor\
. 
NOTICE: To avoid damage to the microprocessor, hold the screwdriver so that 
it is perpendicular to the microprocessor when turning the cam screw. 
1.  Follow the instructions in 
Preparing to Work Inside the Computer. 
2.  Remove the 
keyboard. 
3.  Remove the 
fan. 
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. 
4.  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.

Installing 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 ZI\
F 
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.
2.  Tighten the ZIF socket by turning the cam screw clockwise to secure the \
 microprocessor module to the system board. 
3.  Perform the steps in 
Removing the Microprocessor Module in reverse order, 
beginning with 
step 4. 
4.  Update the BIOS using a flash BIOS update program floppy disk or CD. For\
  instructions on how to flash the BIOS, see 
Flashing the BIOS.
