I acidentally dropped my macbook today (only about an inch...), it continued working for a minute but then froze. i forced it to shut down and then tried to restart, but it sat in the grey screen with the 'loading circle' spinning, restarting the loop every 5 or so minutes. i tried to reset the PRAM, but all that did was make the start up sound come back. Another strange thing is that when the screen is up, the power light is off, but when i shut the screen, the power light goes on (it doesn't sleep, it just stays on the grey screen). this is really irritating as i love my laptop dearly, someone please help
