Replacing Notebook Components
Loosen the three or four screws (these screws cannot be removed) that secure the cooling
assembly to the system board. Use the numbers stamped in the metal next to each screw
and loosen the screws in reverse numerical order (start with 4, then 3, then 2, then 1).
When loosening the cooling assembly's screws in the numbered holes,
loosen them in reverse numerical order.
The number of screws varies by model.
