Whenever I close my macbook(sleep mod) I can hear the sound that it makes when you open it. BUt it's still close and in sleep mode. Did I explain it well?
When my MacBook wakes up I can hear the hard drive spin up for a very short time. Is that the sound you're hearing? Does it stop after awhile?
Yup! that's the sound I hear. It does stop for a while then it spins again and again. The lid is of and it's on sleep mode. So what I do is I just turn it off completely. It's a bit annoying tho. What do you think's the problem?
Do you have anything connected via USB?
