CD/DVD Drive not showing in BIOS...

[pg07143]

I have had two HP DV6 laptops come in for repair over the last 5 days. Neither of these machines recognize the CD/DVD drive - not even in BIOS. I wrote the first one off as a bad connector on the motherboard, but 2 in one week??? Possible I suppose, but I was wondering if anybody had any insight on this problem? The drive doesn't show up in BIOS, the boot menu, or device manager. This is not an upper/lower filter issue.

Never found out what it was, but I had a desktop machine come in like that. Funny bit was that it would all come to life when I put a disk in it. From what I remember, I swapped the drive for another, re booted and all was OK. Shutdown, swapped back to original drive, booted and worked. Have not heard back since.

I have come across this problem a few times, it seems to be a master / slave issue im guessing,

I swapped the drive with a new DVD drive and that one worked.

Even though that drive worked in another laptop, so my only explanation I can think of is either the IDE controller or the master slave drive settings, but on laptops you dont have the jumpers on the back like normal 3.5 drives.

Maybe try a Bios update?

Have you tried removing the drive, and replacing it with a known working one?

A lof of laptops, have the same size / type of cd etc, if needed its usually a case of removing the back plate of the drive, and a simple swap over.

Failing that, I fail to see how a bios update would help. It could be the actual connector on the laptop mobo is faulty, in which case, you would need a replacement connector, which could be a send off to be repaired, or if your confident enough, replace it yourself.
