I'm working on a EnPower laptop. It has a model# of N243S8 and has a handwritten sticker stating ENP875. Everything works on this machine but the DVD/CD-RW combo drive is not operational and does not show in My Computer. Device manager shows other devices - ? peCombo LSC-2408 with error code 28(drivers not installed). I'm not understanding why I need drivers for a combo drive under Windows XP Professional SP2. I've found various websites with drivers and such but nothing at all resembling the need for a CD driver. I got advise for repairing high/low but that did not help or I did not understand the resolution. I installed also generic Windows driver but that just changed it from other to CD drives with the same situation. ANY help would be greatly appreciated. I'd give 1000 points if I could.
