I bought this entry level MacBook in the beginning of September of this year. 2.0 ghz C2D, 120 gig hdd, 1 gig of ram and a combo drive. However, there seems to be a serious issue with the optical drive (combo drive). If I put a blank CD, or any type of CD for that matter, it attempts to read it (I hear it spinning inside the drive), but then ejects randomly. I tried to put in the restore disks just to see if they would stay in, and they did. Does anyone know any possible fixes to this problem?
