Why does my fan increase noise while using normally?When I wake up the MacBook from sleep mode the fan is quiet and while using it the fan increase noise and gets really loud...
Rispondi a "white MacBook won't come out of sleep /hibernate"Something has interrupted the MacBook in sleep mode. To fix this, press and hold the power button until the sleep light turns off then boot the MacBook up again.
Rispondi a "My computer won't boot, i'm getting a folder with ? on it"This indicates that some critical OS files cannot be found, or a corrupted OS or maybe even (as mayer says)a HD failure.
