i Was Using My Ibook And The Last Thing Running On My Ibook Before This Dilemma Was The Voice Recognition Program. Out Of The Blue My Ibook Shut Off And When I Tried To Restart My Laptop All It Did Was Turn On But Would Not Do Anything More Than Just The Power Light Glowing. My Ibook Would Not Boot Up ...no Os...no Nothing Except For There Is A Lil Box In The Center Of The Screen That Flips From The Mac Man Icon To A Question Mark. But That Is Absolutely All It Will Do. Can Someone Please Help Direct Me In Solving This Issue. I Am New To Mac And Am Devastated By This Problem. I Am Enrolled In College And Every Bit Of My Schoolwork Is On My Laptop. I Am Desperate For Assistance!! Thanks In Advance!!
