we have the same series laptop and the same issue. I could not fix it, even tried different cdrom drives. Its the controller, and oddly it does show in the device manager. It just don't work at all.
Curious, do you BSOD? and log back into windows with this error message "Your AMD processor as stopped working..."
Perhaps your may be fixable....search for "upper and lower filters for cd rom" in google. Follow the procedure you find on it and restart. It will require going into your registry and deleting them entries. Good luck.
