My wife dropped her Macbook Pro from about 12 inches above the ground. It struck the corner of the unit, no visible damage anywhere. But now, it won't boot up. It loads the grey screen with the darker grey Apple icon, and a bar measuring boot-up progress shows. But the bar only goes up halfway, then sticks. It will say that way for hours. Is there anything I can do? Some sort of button press or reset? If the answer is 'take it to tech, there's nothing you can do' then I'm pulling the hard drive and walking away. Its a 2010 (?) and has been getting more and more sluggish (as their products tend to do). That grey screen boot-up has been slower and slower of late. Time for a replacement anyway. It seems Apple pushes out updates and eventually, your product can no longer handle them, forcing an upgrade to the newer units. PS, I'm a PC guy, so my Apple knowledge is very limited, but I can get around in a PC architecture OK.
