Table 26. Installation of the fan assembly
When installing the fan assembly, do as follows:
v Before you attach the fan assembly to the computer, apply thermal grease, at
an amount of 0.2 grams, on the part marked a as in the following figure.
Either too much or too less application of grease can cause a thermal problem
due to imperfect contact with a component.
v Make sure that the fan connector is attached firmly.
v When attaching the fan assembly to the frame, take care not to damage the
heat sink ( b ) of the fan assembly.
