    my powerbook g4 a1138 has always worked very well until recently. The battery went dead after 368 cycles. I relaced it with a new apple G4 battery model a1078 10.8V (not the recalled one).
    The problem is this, if i have the 65 watt adapter in and the battery, which is fully charged installed, the powerbook will boot up but within 5 - 30 seconds the powerbook will suddenly go off and i will have to hold the power button down until the screen flashes then it can be started again.

    If i boot to safe mode this does not happen, i can use the powerbook as normal with the ac and battery. And it will never have a problem. But only from safe mode.

    Also if I remove the battery and only use the ac the problem never shows up. But, if i'm already running with the battery in and on ac and pull the ac plug my powerbook shuts off.

    Can someone with more experience be of help?

    Last night I reinstalled 10.5.8 and have all the updates.

    thank you

    Problem solved after a year video flex cable

    this ended up being the flex video cable.

    it had a very small short in it, the position of the screen was the temp fix.

    need to replace the flex cable for about 20.00

    bill
