    Heya guys. I recently acquired an old Tibook M8407 model.

    When I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off!

    After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time.

    Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen.

    I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base.

    Has anyone heard of any problems like this before?

    I believe it's running a 500mhz processor and has 512mb of Ram.

    Thanks in advance!

    Yes I figured.. I had my doubts that this spontaneous shutdown was a special feature created by Apple.
