I have an Aluminum PowerBook G4 1.67Ghz since 2006.

3/4 (from bottom to top) of the LCD becomes either black or is jumbled each time I turn on the MAC or move the screen. I need to press the LCD at several locations in order for this problem to go.... any advice ?

re: Polanskiman; this is usually caused by a loose ribbon connector on the rear of the LCD. Open up the display, remove the LCD, lay flat and re-connect the ribbon plug.

Grasp the back corners of the upper case and pull up.

    • Do not pull the upper case off yet; you still need to disconnect the keyboard and trackpad cable.

  • Lift the back of the case up and work your fingers along the sides, freeing the case as you go. Once you have freed the sides, you may need to rock the case up and down to free the front of the upper case.

First of all, awesome guide. I am using it in July 2015, and there is no way I could have successfully navigate the typical Apple laptop Rubik's cube of Powerbook maintenance.

Second, there is a REAL trick to removing the upper case here, and it involves knowing what those stupid internal metal catches look like so you can free them without folding your aluminum case into a pretzel.

in my g4 there is also a big transparent ribbon (for keyboard?), to the right of the amber trackpad ribbon, that i disconnected before removing case cover.

re: ykuwabara; this is due to the differences between the Model A1095 (yours) and the newer A1138 (illustrated here). The A1138 combines the keyboard and trackpad signals into one cable.
