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.
