Hello everybody,

Got a big problem, when i was working on my master thesis document, i closed my macbook(physically with display down). He goes into standby. But when i opened it again, he didn't woke up. Pressed every keys, touched the touchpad, nothing happened. Then i hard rebooted, nothing happened, only the fan started making extreme loud noise. So i did a hard shut down, disconnected everything(powersupply, battery,usbstick,etc etc). Inserted the battery and the powersupply again and booted. My screen lit up, logo appeared, and the cicle(busy icon of the mouse) but it didn't rotate. Also the fan started making the loud noise again.

Can anybody please help me, i need to give my thesis document next friday to my school... it's very important...

Thank you very much
