DVD/CD Drive Malfunction

I have major problem... I can't fix the DVD/CD-ROM drive for my Sony Vaio laptop.
Here's a list of things that are wrong with it:
1. It wont respond to the manual eject button.
2. It only ejects if I click the eject command from the CD-ROM drive icon in My COmputer.
3. It does not recognise any type of disk (CD, DVD, Blank media, etc.)
4. The LED never lights up, even during restart.
The laptop is only a month old, it's brand new. I tried burning data to a blank DVD-RW with Nero 5.5, however Nero would only give me the option to burn CDs but not DVDs (the options were all greyed out.) After giving up, I finally used the crappy burning software that came with the Sony (Sonic Record Now!) with no problem. Everything went smoothly and after 20 minutes, I had a shiny new data disc. The next day, the problems began, and now I'm here.
Here's a list of things I tried:
1. Uninstalled the drive in device manager, rebooted.
2. Uninstalled the Secondary IDE channelin device manager, rebooted. In both cases Windows XP reinstalled it, but the DVD/CD-ROM drive still has the same issues.
3. Deleted the Lowerfilters (no Upperfilters were present) at

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} and also at ControlSet001 and ControlSet002, rebooted. Still nothing.

Under the DVd/CD-ROM properties, it says the device is working properly. I dont get any error messages when I click the Explore or Open commands from the DVD/CD-ROM Drive Icon in My Computer, and it just opens the drive like a blank folder, whether it has a disc or no disc in the drive. Everything in the Hardware device manager seems to work; there are no little yellow attention symbols or the like. DMA was always enabled

Any Ideas??

Welcome to the forums Dude123

A] Why not try a restore, or better yet a reinstall of XP?
B] IF its still got hardware probs, then take it back and ask for a new one.

Maybe there are other options, but these are what I would do.

and if youre using Nero 5.5, get the latest one, 5.5.10.56.

your laptop is new so take it back and let them fuss around with it,you may void your warantie trying to fix it yourself
