Re: 2019 X1 Yoga Gen 4 Poor Battery Life

My driver version is much different than yours. The current Lenovo Power Management Driver version is 10.0.115.0 and I rolled it back to 10.0.106.0. I am wondering why our versions are so different. Anyway, I'm waiting to see if the rollback has any effect.

It took a few minutes. I do see a difference but it is minor. The battery life meter went from 4 hours to 6 hours with wifi on after a few minutes. Not the significant change I was expecting, but still better than nothing.

Re: 2019 X1 Yoga Gen 4 Poor Battery Life

A quick search on the version number you gave shows it is for Lenovo Power Manager for Windows 10 (Version 1703 or Later) and not for Lenovo Power Management Driver.

 

What I had to do was go into Device Manager > System Devices. Right-click Lenovo PM Device and click properties. Click the Driver Tab and it will show the currently installed version and should also have a button to "Roll Back Driver" if it still has the previous version available.

Re: 2019 X1 Yoga Gen 4 Poor Battery Life

I found the Lenovo PM device driver but unfortunately, mine is already on the version 1.67.17.28 that you rolled back to. I don't have another roll back option.

My battery meter is reading 7 hours at about 70% battery with wifi on and browser running. Would like to compare to how yours is performing. How does this compare to your performance?

Scratch that! My battery meter now says 3 hrs 39 mins with 67% remaining. Still disappointing to me.

And we're back...

Move delayed but still coming
