DVD drive is not working – Error code 39

Had some problems today with several DVD drives on HP DC7800 SFF desktop PC’s. The error code was 39. After some troubleshooting I found the solution. Here is the solution to the error code 39 issue.

  1. Choose Start > Run.
  2. Type regedit in the Open text box and click OK.
  3. In the Registry Editor dialog box, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetContro lClass and select the {4D36E965-E325-11CE-BFC1-08002BE10318} key, which appears as a folder.
  4. Select File > Export (Windows XP) or Registry > Export Registry File (Windows 2000).
  5. In the Export Registry File dialog box, select Selected Branch under Export Range, name the file (for example, CDDVDkey.reg), and click Save to save the file to the Desktop.
  6. In the right panel of the Registry Editor, select the LowerFilters line, and then choose Edit > Delete. Click Yes in the Confirm Key Delete dialog box.
  7. Select the UpperFilters line, and then choose Edit > Delete. Click Yes in the Confirm Key Delete dialog box.
  8. Close the Registry Editor.

Mouse stops working in Office 2007

I reinstalled my laptop (Lenovo T61) last week. There is nothing like a clean reinstalled PC!

After this I experienced a very annoying problem with Outlook 2007 and Word 2007. The mouse would simply stop working in the “edit area” of the programs. So if I needed to move the cursor, click on a link or copy some text etc. I would have to use the keyboard.

I googled a lot and found a lot of suggestions – most of them related to bad registry settings. None of them worked. I tried to repair Office 2007 and I tried to remove and reinstall Office 2007. That did not help either.

No add-ins were installed so this was not the problem.

Finally I cracked this one. It took me a few hours though. After reinstalling the laptop I decided that I wanted to try the IBM/Lenovo Client Security Solition. Could this software be causing the problem. I tried to disable this software and the problem was gone!

I went to lenovo’s site and found a patch for this specific error. You can download it here:


I have applied the patch and now Office works like a charm again. Hopefully this can save you a lot of time if you are experiencing lack of mouse support in your Office 2007 installation.
