    help!! ibook g4 power issues
    My ibook g4 14" (purchased August 05) only works when plugged in. If I unplug it, it immediately shuts down and will only power up when plugged in again. Here's what I've done:
    1. after much research and pmu resetting, I purchased new battery.
    Problem didn't go away.
    2. I have reset the pmu, pram, and restarted in Open Firmware Mode (typing reset-all)

    Here is what my power info says:

    Battery Information:

    Battery Installed: Yes
    First low level warning: No
    Full Charge Capacity (mAh): 4920
    Remaining Capacity (mAh): 4920
    Amperage (mA): 0
    Voltage (mV): 16716
    Cycle Count: 1

    AC Charger Information:

    AC Charger (Watts): 50
    Connected: Yes
    Charging: No

    I'm dying here. What help can you offer me?? Thanks.

    Specs:
    Mac mini g4 1.5ghz, powerbook g4 1.5ghz aluminum, iphone 8gig, ipod 30 and 4 gig
    Similar Prob.
    I had a similar prob. only my battery had in X where battery life would be..it made no since cus the battery was fully charge and in the book and a power source was plugged in.

    How I fixed the problem was with Tech Tool Pro. its like a hundred dollar program...deff worth it, but if you give me your email I might be able to send you the disk image and you could use it from there!!!!

    If you bought applecare for your ibook, Techtool comes on the CD that was in the box. If not, I think it is even offered on apple's website: https://support.apple.com/techtooldeluxe/main?id=dl

    The tech tool that comes with apple care is like a amateur program...it might work but the pro package would be to get Techtool pro

    ibook battery issue
    While downloading update files using fully-charged battery power, heard clear "click" and screen went blank. Could not restart until plugging into mains. Date time has reverted to 1969. Unplugging mains causes immediate shutdown. Suggestions as to cause or recommended recovery procedure welcomed.
