Macbook Pro Retina is beeping in each 5sec without stop
I've bought in August, 21 and start beeping today.
I've put mute and the noise still beeping.
Interesting that the beep noise sometimes became an low buzz noise.
I've started several times and the noise stops just when the computer was off.
I really appreciate some help.
Tks!
MacBook Pro with Retina display, OS X Mountain Lion (10.8.1), SN C02J5KV8DKQ1
