Hello, Whenever I start up my 13" April 2010 MBP, there is a sound from the optical drive. This used to happen with my old MacBook - no big deal. However, when I got this laptop, it did not do this - this issue has arisen only lately. The EFI 1.8 notes says that this issue is resolved. I downloaded it and tried to run it, getting a message that my MBP is already up to date. I've reset the PRAM and SMC as well, to no avail. Any ideas? Anyone else experience this? Edit - Just reread the EFI 1.8 patch notes. It says it removes the sound for wake up from sleep, which I can confirm does not happen. Maybe I'm remembering wrong? Anyone with the 13" April 2010 MBP also have the optical drive make a bunch of noise on startup?
