OS is Windows Vista problem : Missing CD/DVD device in the Device Manger
1. Restart the HP notebook and press F10 for BIOS
2. Make sure the CD/DVD is enabled
3. Change the sequence of boot
-- I moved the Floppy to the First or some thing , Orginally the CD/DVD was first in the bootSequence )

As I understand from other posts, I may lose DVD again . I will try changing the boot seq again and see if does the magic

I used the fix to get my dvd drive to work after having iTunes on my computer and it worked. My comuter just updated with the newest iTunes update the fix is not working now. Please help.

Had this problem with my DV6701. Not exactly sure when it happened, whether it was the install of Win7, or installing iTunes. My DVD was recognized in my device manager, but wouldn't read cds or DVDs, and never showed up under my computer. Decided to try the easiest "solution" listed here with the registry update deleting the upperfilter value, and it worked for me.
BTW, there were multiple places I had to update the registry as I didn't have just one "control" folder.

I wasted hours on this...
tried all the install this and uninstall that advice...
in the end I took out the rubber plug at the back.. unscrewed the DVD drive and popped it out.
then I blew all the dust out of it and plugged it back in.
I thought I would go to all the hassle of joining up with HP, answering all their stupid questions,... so I might prevent some other poor sucker going through the wasted hours that I did...
take it apart and blow the dust out (there was a lot ... household dust...)

***reply from HP on issue with the cd / dvd player all of a sudden not working and no drivers **
This is in response to your e-mail regarding the HP Compaq 6000 Pro Microtower PC (ENERGY STAR).
I understand from the case notes that you are experiencing an issue with the DVD drive which is not functioning properly.
To facilitate accurate problem identification and the fastest possible resolution of this issue, it is important for us to troubleshoot remotely.
1. From how long you are experiencing the issue?
2. Any recent Hardware/software changes?
3. Is the DVD is detecting under My Computer and in Device manager?
If no, please perform the Upper filter and Lower filter by following below steps and check for the issue.
Click the following Microsoft Fix it Solution to clean the registry filters automatically:
1. If you cannot use the Microsoft Fix it Solution, continue using these steps to clear the upper and lower registry filters manually.
2. Unplug all non-essential external plug and play devices, especially cameras.
3. Click Start, and type "regedit " into the Start Search field.
The registry editor window appears.
4. Select Computer in the main window.
5. Click File, Export, type a filename that is easy for you to remember, and click Save.
A copy of the registry has saved for back-up purposes to the Documents folder. If problems occur after using these steps, browse to the file and double-click it to restore the registry.
6. Click the plus sign (+ ) next to the following items in the list:
Current Control Set
7. Select 4D36E965-E325-11CE-BFC1-08002BE10318. Make sure you have selected this exact key name.
8. Select the Lower Filters value and press the Delete key. Confirm the deletion by clicking Yes.
9. If an Upper Filters value is also listed, selects UpperFilters in the right window and presses the Delete key.
Confirm the deletion by clicking yes.
10. Delete all other Upper Filter and Lower Filter values within the 4D36E965-E325-11CE-BFC1-08002BE10318 key if they exist.
11. Close the registry editor and restart the computer. The disc drive should now be recognized by Windows. You may need to uninstall your disc recording software, restart the computer, reinstall the CD/DVD writing software, and then restart the computer again if the software no longer recognizes the drive
You could get more information from the following web-link: (this link refers to vista) suposed to work with other operating sytems too

Hey guys!!! I found out i was having this issue with my Windows 7 machine.. and i resolved it!..
Follow these steps:
1) Uninstall your CD/DVD drive from your system
2) Reinstall your CD/DVD drive
3) Right click on your hard drive and go to properties
4) SWITCH YOUR REGION TO YOUR COUNTRY
Mines was set to region 1 (US) and my DVD's would not work, i then updated this to UK (region 2)!
Let me know how this works guys!
