Power Manager 8 forgets battery threshold settings on L420 and Windows 10

I have tried to adjust the battery charging thresholds for my L720 using Power Manager 8. The idea is to preserve the battery by charging only between 46% and 50%. The system accepts these settings and shows them when the pointer hovers over the power manager in the toolbar, but forgets them every time the computer goes into standby or hibernation. This makes the settings pointless. I am running Windows 10 and believe that both Windows and the power manager are the latest versions available.

I have now noticed that the battery charging thresholds disappear even while the computer is being used, not just when it goes into standby or hibernation.

I like how all the Lenovo users out there are oblivious to these flaws. I have been questioning if the power manager battery maintenance even does anything. My thresholds have never changed, it has never warned me of anything and never notifies me of anything. I have done 675 charge cycles and my battery now lasts 1 hour on light use.

And we're back...
