I'm sure you all know the sound that the Macbook does when you start it up from sleep or something. Anyways, my problem is that that sound changed from what it was before. Now it's like a much slower and longer version of the sound I've been hearing before. Do you guys think that it's some kind of malfunction? DVDs and everything run great but the sound is bothering me.. Oh and I have an early 2008 Macbook Pro. The drive is HL-DT-ST DVD+-RW GSA-10N.
