When replacing the secondary fan, must the PC card cage be removed?
The repair guide for replacing the 867MHz TiBook's secondary fan includes steps (32 & 33) for removal of the PC card cage. The PC Card cage is located on the opposite side of the logic board relative to the fan location. For the life of me, I am unable to determine why this step is necessary in the course of installing a new secondary fan. Is this a leftover (i.e. copy & paste?) from a different but related repair guide for this Powerbook model?
Side note: The repair guide specifies that a 4mm nut driver is required, but its only use is to assist in the removal of the PC Card cage.
Any clarification or assistance would be appreciated.
