Does anyone here know how to make it work on a Thinkpad 10 running Windows 8.1? Editing the registry lets the Settings App show the right message about charge start and stop percentages, but charge start and stop are not actually affected at all.

Some time ago I found website. whose owner created his own Power Manager with discussed function for Windows 8.1. Unfortunetaly, the website if offline. However, I downloaded this utility some time ago. Here:
Can you give us a feedback if it's working on Win 8.1 and/or Win 10?
The part of ReadMe.txt
About ***** The ThinkUtils Power-Manager is a non-official replacement of the official Lenovo Power Manager on mobile Think-systems running Windows 8, or higher. It offers monitoring of the system power status and controlling the charge thresholds of your battery. Although targeted on newer generation ThinkPad-machines, it will also work on non-ThinkPad PCs but with limited functionality.

these setting works for my x240 but threshold is set for only removable battery,
but how to set threshold for buit-in battery?

I have no ideal.
It's a shame, that such a great functon was removed from ThinkPad's. Now they are not different from another mobile workstations...

To everbody who is still searching for a solution for this strange behaviour:
I resolved the issue that my T440 is ignoring the values set in the registry by downgrading Lenovo Power Management Driver and the Lenovo Settings Dependency Package to the versions mentioned in the first post.
After having done that, charge threshold again works in Windows 8.1. I use the third party software Magnum44pl mentioned in Post 65 to set the values.
Don't know why Lenovo doesn't support this really great functionality in their newest versions of the drivers but downgrading to the versions mentioned in the first post helped. Really weak behaviour from lenovo ignoring this issue so far!

i read through the whole discussion, as i have to deal with the same problem on my yoga s1 (win 8.1)
i tried to change the registry entries by myself as well as by two different programms.
anyway i didn't work.
as it seems to work, when you use the older version of the power management driver and the lenovo settings dependency package, i woul like to downgrade, too.
can you please discribe, how you did this?
i cannot find the older versions of the mentioned drivers.
at the moment im running pm driver (184.108.40.206) and the lenovo settings dependency package (1.6.36.00) and would like to downgrad to v220.127.116.11 and v18.104.22.168 as written in the first post.
thanks for your help!
