That means that the computer's not finding a bootable partition on the disk. I'd do an Apple Hardware Test from the DVD that was included with the MacBook. If it reports no problems, install OS X again, using the Archive and Install option to save existing data. If it does report a problem with the hard drive, it'll probably need to be replaced.
I am getting a "folder with a question mark" when I turn my laptop on. Please help.
Thank you
