Description
Spare part number
Heat sink
645326-001
CAUTION:
The bond between the heat sink and the processor may be very tight.
If the computer will power on, before removing the heat sink, turn on the computer until it warms the
heat sink. Warming the heat sink lessens the bond between the heat sink and the processor, thereby
making separating them easier.
Make sure not to pull the processor out of the socket when you lift the heat sink, especially if you cannot
warm the heat sink prior to removal. Inadvertently removing the processor can damage the pins.
1.
Prepare the computer for disassembly (
Preparation for Disassembly
on page
54
).
2.
Remove the computer access panel (
Computer Access Panel
on page
55
).
3.
Remove the front fan (
Front Fan Assembly
on page
85
).
4.
Loosen the four silver captive Torx T15 screws that secure the heat sink to the system board.
CAUTION:
Remove heat sink retaining screws in diagonally opposite pairs (as in an X) to even
the downward forces on the processor. The pins on the socket are very fragile and any damage to
them may require replacing the system board.
