Do Not Remove Heat Exchanger from Microprocessor Board
Unless the microprocessor board needs to be replaced, do not separate the
heat exchanger from the microprocessor board when taking the
PowerBook (FireWire) apart. When the heat exchanger is removed, the
phase change material covering the microprocessor chip may need to be
removed and replaced. For further information, refer to the Take Apart
chapter of this manual.
