The processor module assembly can be removed without removing the palm-
rest. To remove the processor module assembly, see Figure 4-16 and follow
these steps:
1. Remove the keyboard.
2. Remove the heat-sink fin cover.
3. Remove the two 14-mm screws securing the processor module assembly
to the system board.
4. Lift the processor module assembly off of connector U14 on the system
board. Lift from the outside first.
5. To disassemble the processor module assembly, slide the top plate free of
the interlock tabs. The assembly separates into upper and lower plates and
reveals the processor module.
6. Remove and replace the thermal pads only if needed. The pink pad covers
the BX chip and the gray pad covers the processor chip.
When installing the processor module assembly, put pressure only on the
areas where the connectors on the processor module assembly and on the
system board fit together. Pressing on other areas may break pins or
connections.
