    need to restart

    Apr 28, 2012
    I have a 1.5ghz aluminum powerbook g4 that freezes before it reaches the mac os loading screen most of the time. Dimm0, the built in 256mb built in memory, is not being recognized.

    Randomly(usually after countless restarts) the computer will start up just fine recognizing dimm0 and the 1gb of added memory.

    Is there a way to disable dimm0 and just have the computer use the add-on memory without taking the computer apart and removing the on-board memory?

    Short answer: no not as far as I am aware. If I recall correctly DIMM0 on the powerbooks was hardwired onto the motherboard.

    You are looking at a motherboard replacement. I guess in theory a solder reflow could fix it; if the connections were bad. (not likely)
