It was in sleep mode opened up, threre are no dents. I shut it off and when I start out up again, it's stuck on the silver screen with the apple on it. I can hear the fan running. Is there anything I can do?
It should, but as the HDD was shut off during sleep (this accident happened during the Mac sleeping?), the SMS was not activated, but the read/write head was also parked. Maybe it is something else then.
Was it a Macbook or Macbook Pro? The MBP aluminum usually always dents with a drop which costs a heck of a lot to replace. If it is just the hard drive, which is what I think it might be, thats not too bad considering.
You can
a) try to boot from a SL install disc (if it's a pre Lion model), and maybe run a hardware check
b) connect an external HDD, boot into recovery mode and try to install OSX and run the laptop from the external disc
If the above is mostly successful, you just have to replace the HDD and it could be fine.
Could be a lot of things....Dropping the machine could have unseated RAM, damaged mountings, loosened connections etc. etc. A trip to the store would be your best bet OP.
