HP CQ41-208AX, CQ41-206AU, CQ41-205AX, CQ41-204AU, CQ41-206AX manual Remove the heat sink assembly

Removal and replacement procedures

✎The thermal material must be thoroughly cleaned from the surface of the fan/heat sink assembly and the system board each time the heat sink assembly is removed. Thermal material is applied to the discrete fan/heat sink to correspond with components on the system board as follows: the processor 1, the Northbridge chip 2, the ATI video chip 3, and the capacitors 4. Replacement thermal material is included with all system board, fan/heat sink assembly, and processor spare parts.

✎Steps 5 and 6 apply to computer models equipped with graphics subsystems with UMA memory. Steps 2 through 4 apply to computer models equipped with graphics subsystems with discrete memory.

5.Loosen the four captive Phillips PM2.0×10.0 screws 1 that secure the heat sink assembly to the system board.

6.Remove the heat sink assembly 2.

✎Due to the adhesive quality of the thermal material located between the heat sink assembly and system board components, it may be necessary to move the heat sink assembly from side to side to detach the assembly.
