Are these symptoms of battery failure?

    I've had an iBook G4 (1.07 GHz 12 in) for two years. Lately my iBook would suddenly shut down without warning. Here are things I've noticed so far:
    1. Each time it did that, the iBook was not plugged in;
    2. The battery was at 30-45%;
    3. If the internet connection was not on, at reboot there would be an error message saying that the clock had been set to March 24, 2001;
    4. When I tried to reboot it without plugging in, it started to reboot, then died without having finished rebooting. I pressed the button on the battery, there was nothing. But after I plugged it in for about a minute and pressed the button again, two lights went on.

    So the questions are:
    1. Do I need a new battery? My battery was slightly less than 2 years old.

    2. I read an article about "resetting power management unit." would that work? Can I reset it without erasing everything on my computer? If that is the problem, then even if I get a new battery, the problem would still persist, wouldn't it?

    3. Are there other problems that can cause these symptoms?


    Please help...

    Thank you very much!:)

    Well if your iBook is about two years old. I would say that your battery is going bad. As batterys don't last forever

    Your suspicion is right: those are classic signs of a failing battery.
