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.
