PowerBook G4 (17-inch) Take Apart - 71

Logic Board

Preliminary Steps

Before you begin run the computer until warm (if possible) to help soften the thermal

materials on the logic board, then shut it down and remove the following:

• Battery

• Top case

• SuperDrive

• Right speaker

Procedure

Warning: Flexing of the logic board can break solder joints to chips. To prevent

damage to the board, guard against unnecessary ﬂexing. Do not hold the board by

the ports end or by the narrow neck at the fan cutout, as the board’s weight can ﬂex

the board at this narrow point.

1. Turn the computer over. Disconnect the cables shown.
