    I would try the things listed in the basic trouble shooting article

    http://www.mac-forums.com/forums/app...es-thread.html

    - Battery charging problems
    - Sudden loss of power whilst running off battery
    - iBook refuses to switch on
    then you might need to reset the PRAM (Parameter RAM) or the PMU (Power Management Unit).

    To reset the PRAM, hold Apple-Option-P-R simultaneously at the Apple logo.
    To reset the PMU, hold down “Shift-Control-Option-Power “.

    Specs:
    2GHz Mac Mini 2GB RAM 160GB 10.6.2 | MDD DP 1.25GHz G4 1.5GB RAM 10.4.11 | 233MHz iMac G3 10.3.9
    Apple = Command key with this symbol: ⌘

    Option = Alt key

    for the PRAM, hold it until you hear it chime twice, then release the keys.

    try this
    power off ...

    power back on and before the apple ding
    hold down all of these keys

    cmd (apple) opt and the o and f key

    this should bring you to an open firmwar command prompt

    Type in

    reset-nvram and hit enter

    then

    reset-all and hit enter .. it should reboot.

    see if that helps
