L430 DVD (or PowerManager) problem

2019-10-06, 1:22 AM

L430 laptop

Windows 10 64bit - build 1903 (upgraded from Win7)


I was able to use the DVD without any problems 3 or 4 weeks ago (but can't be sure exactly when and don't know what windows version was in play at the time). 

I suspect an intervening Windows Update has rendered the power manager and/or dvd drivers inop, but I'm not sure what else to try to get the DVD back.

The first symption was a popup dialog when accessing the DVD:


There was a problem starting C:\WINDOWS\System32\Lenovo\PowerMgr\PWMTR32V.DLL. 
The specified module could not be found.

I've tried a number of things:

  • uninstall the power manager and PM devices
  • installing the latest version of PowerManager from the Levono support site
  • install latest dvd driver

At this point, I no longer get the PowerMgr DLL error and the Device Manager says that the drive is working properly and the driver is up to date.    I'm no longer seeing the DLL error but the drive isnt actually working -- when I insert a known-good disk into the drive, nothing happens -- the drive does not mount.   Application prompts "Insert disk".


Thanks for any new ideas you can suggest!

I just had a similar issue with a T430 laptop.  When I upgraded Windows10 to the lastest version (18363) the DVD icon changed to a white square with a message saying something related to 32-bit power manager was deactivated (pwmtr32v.dll) and the same popup you describe showed up if I click on it.  If I opened the DVD tray and closed it the icon would return to normal for a few seconds. The DVD unit still worked, if I inserted a CD or DVD I could access the files but the error message was weird.


The solution I found was first to restore to a previos working windows10 version (10240), poweroff the laptop, remove the DVD unit, download and run the windows10 upagrade assistant (from microsoft) and when the upgrade was done, power off the laptop and reinsert the DVD unit.   I hope this helps.
