Removing the Processor
1. Follow the procedures in Before You Begin.
2. Remove the hard drive (see Removing a Hard Drive).
3. If installed, remove the floppy drive cable from the cable routing clips on the heat sink assembly.
4. Loosen the captive screw on each side of the heat sink assembly.
5. Rotate the heat sink assembly upward, and remove the assembly from the computer.
Lay the heat sink down on its top, with the thermal grease facing upward.
6. Pull the release lever straight up until the processor is released.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your
computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
CAUTION: Despite having a plastic shield, the heat sink assembly may be very hot during normal operation. Be sure that it has had sufficient time
to cool before you touch it.
NOTICE: Before rotating the heat sink assembly upward, twist the assembly side to side to help break the thermal grease bond between the heat sink
and the processor. This is to prevent damage to the processor from pulling the processor out of the socket while rotating the heat sink assembly
upward.
