HP Pavillion DV9000

[L0u33z]

Hi,

was wondering if anyone could help me please, i installed windows 7 onto my laptop a while ago and as i don't use my CD-ROM very much i've only recently realised it no longer works, i've had a look under device management and 'coprocessor' has a yellow triangle by it and ! mark ?

I'm really useless when it comes to technology but was wondering if anyone could help me in finding out how to fix this problem please?

i've tried to update driver software but that does not work, and states windows could not find driver software for your device

and underneath properties it states;

"The drivers for this device are not installed. (Code 28)

There is no driver selected for the device information set or element."

thanks again for any help really appreciate it

Hi LOu33z,welcome to the forums, download and reinstall the chipset drivers Software & Driver Downloads HP Pavilion dv9000 CTO Notebook PC - HP technical support (United Kingdom - English) you may have to install them in compatibility mode for Vista as they are the only drivers supported

Hi LOu33z, Glad we got the coprocessor sorted for you, Is the cd drive listed in device manager? It's quite normal for it not to show in windows explorer

Hi thank you for getting back to me, the CDrom is not listed in the device manager at all, there isn't even an option to do with CDrom drive in any of the lists on my device manager, i've done the scan from the above link, (thankyou very much btw) and it states;

"windows didnt detect an optical disc drive. It might be disconnected or unplugged. check the drive connection, or plug the drive in."

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration
(How to back up and restore the registry in Windows )
in case problems occur.

This problem may be caused by two Windows registry entries that have become corrupted. To use Registry Editor to delete the corrupted Registry entries, follow these steps:

1. Press the Windows logo key + R to open the Run dialog box.
2. Type regedit in the Run dialog box, then press Enter. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow
3. In the navigation pane, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
   
4. In the right pane, click UpperFilters.
   
   Note You may also see an UpperFilters.bak registry entry. You do not have to remove that entry. Click UpperFilters only. If you do not see the UpperFilters registry entry, you still might have to remove the LowerFilters registry entry. To do this, go to step 7.
5. On the Edit menu, click Delete.
6. When you are prompted to confirm the deletion, click Yes.
7. In the right pane, click LowerFilters.
   
   Note If you do not see the LowerFilters registry entry, go to the next resolution.
