Hi - it powered down after running out of juice and not being plugged in at my desk. I plugged it in and started it up - it makes the Mac Bong sound and then the apple appears. But then a progress bar appears on the bottom of the screen and it doesn't even reach 1/4 of the way before it shuts down again.


I have tried it plugged in, unplugged - no difference.


Please help.

Thank you!


PowerBook, Mac OS X (10.7)

    Hi William,


    We need to make sure of your equipment. Although your Profile says "PowerBook," the OS version says "10.7," which cannot run on any PowerBook. We need a clarification becasue startup problems on real PowerBooks can be caused by different issues that those that affect Mac notebooks that can run OS10.7.
