T510 on startup errors ...missing power manager files

2020-06-29, 22:37 PM

I know this is a much reported issue over the past several years, but I just started getting this error.  I checked the location and found no Utilities folder for Power Manager.  Also Device Manager shows only PM Device and not Power Manager.  When opening Vantage and checking the Battery, I see the comment: "The Lenovo Power Manager driver is not installed or not working properly. Please run Windows Update or manually install it from here. After the installation, restart your computer".  Like a good boy, I followed the instructions but it did not resolve the issue.  I spent all day chasing down "Solutions" on the forum with  no success.  I simply cannot find the .exe file for the Power Manager.  It seems that both the driver and the device settings software are co-dependent.  I have the PM Device Settings file, but need the driver.  Can anyone help?

My battery status seems stuck at 96% and there is no slider or any selection on the icon to make any changes in the charging rate, etc. Is this normal? Did Lenovo or Microsoft remove this feature?Also, I found the .exe file for the Power Manager driver. It is what is installed under the PM device on the Device Manager. Furthermore, I read that Windows Update is supposed to install the Power Manager in Lenovo Vantage, but Windows Update shows everything up to date. Should I try to manually find and install the driver from the Microsoft Update Catalog?
