CHAPTER 3: Replacing notebook components
6Lay the thermal module down in an upright position to avoid tainting your work space with thermal grease.
7Remove the barcode sticker on top of the processor.
8Moisten a soft cloth with isopropyl alcohol and clean the processor die to remove any thermal grease residue. Wipe the die surface several times to make sure that no particles or dust contaminants are evident. Allow the alcohol to evaporate before continuing.
Caution
Do not touch the contact surface of the new thermal module nor the processor die as this may leave dead skin cells or oils from your finger that can result in poor thermal grease performance.
9Apply just enough thermal grease to evenly coat the surface of the processor die.
10Place the new thermal module on the system board and tighten its captive screws to secure it in place. Follow the sequence of the number beside each screw when securing the thermal module.
11Reconnect the cooling fan cable to its system board connector.
12Replace the bay cover, then tighten the cover screws.
