Removal step of the thermal fan assembly
When you install the thermal fan assembly:
• Always wear fingerstalls when handling the thermal fan assembly. Do not touch or hold any part of the
thermal fan assembly with bare fingers.
• Before you attach the thermal fan assembly to the computer, apply thermal grease, at an amount of 0.2
grams, on the part marked
a as shown in the following illustrations. Either too much or too less
application of grease can cause a thermal problem due to imperfect contact with a component. You might
need to peel the thin film off from the rubbers marked
b .
• Do not touch the thermal grease.
• Do not press, touch, or rotate the fan impeller.
• Do not touch the fan inlet hole.
• Do not twist or pull the cable of the thermal fan assembly.
• Do not apply pressure on the top and bottom covers of the thermal fan assembly.
• Do not press the heat pipe. Hold both sides of the heat pipe if you must take the thermal fan assembly.
• Do not shake or drop the thermal fan assembly.
