      CPU thermal device/fan installation

      For ThinkPad W700 and W700ds:

      When installing:

      • Before you attach the fan assembly to the computer, apply thermal grease, at an amount of 0.2 grams, on the part marked [b] 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. For the new CPU thermal device/fan, you need to peel the thin film off from the rubber marked [a].
