Locate the (5) captive screws that hold down the heat sink assembly to the central processing unit and the graphics processing unit.

The captive screws are marked 1-5 in consecutive order, and they will not come off of the heat sink when loosened.

Unscrew captive screw #1 with a JIS 1 screwdriver for one or two turns and move onto the next screw (#2) and so on, in consecutive order.

Continue to slowly loop around the 5 captive screws in order, only loosening the screws one or two turns each time until all screws are completely retracted.

Do not loosen any captive screw fully without moving to the other screws first! This can bend the heat sink assembly and possibly damage the processors.
