Processor

Before installing a processor, make sure the release latches are in the locked position. This
will cause the processor to make an audible sound when it is properly seated in the
retaining clip.
1. Prepare the computer for disassembly (Section 4.2).
2. Lay the computer down on its large base (side with feet) for greater stability.
3. Remove the access panel (Section 4.6).
4. Remove the heatsink retaining clip 1 by pressing down on the clip's extended tab until
it releases from the safety catch.
5. Lift the heatsink 2 off the processor.
6. Release the original processor 3 from the socket by pulling the handle on the ZIF
socket out and upward 4.
7. Lift the processor out of the socket.
To install a new processor, reverse this procedure.
✎
If the heatsink has a thermal interface attached to its bottom, peel off the
protective paper before installing the heatsink.
✎
All units with 800 MHz and faster processors require an active fansink. When
installing the fan, make sure it is positioned so it blows down on the processor.
✎
All units with 933 MHz and faster processors require the chassis fan assembly
(Section 4.21). When properly installed, this fan blows air away from the
computer.
CAUTION: Carefully remove the interface and all residue from the heatsink surface. Thermal
interface heat transmission is reduced if residue remains on the heatsink or the heatsink surface is
scratched.
