|A couple of months ago I replaced the battery on the motherboard of my son's PC. The PC works fine with the exception of the CD/DVD drive. The drive is getting power, and when I place a CD in the drive, the drive seems to be spinning the CD properly (it increases its RPMs as if its reading the disc). But the drive appears nowhere in the device manager, or in the list of devices in My Computer. I have checked all the plugs and cables, and everything seems fine. I have tried re-adding the device using the hardware installation wizard, but I haven't had any success.|
I'm thinking it is a problem with the BIOS setting, but I don't know which setting to change. The PC is a Shuttle XPC and the drive is a Plextor PX-716A.
