We will investigate and feedback you. And you could try disable charge thresholds to test. Since there are some logics to charge internal battery and external battery. You could try charge one battery to be full and then disconnect ac and re-connect to charge another.

Could you help to check if PM device is installed in device manager and provide screenshot?

From the logs, it seems that this device is not detected.

Here is the PM device screenshot. As you recommended it to me, I disabled the charge thresholds. The two batteries are still not fully charged.

It seems that one of the battery is fully charged,

and another one is still in low level.Y

ou may still need to continue to charge it.

and you could try the solution in post below:

and we will investigate why power manager driver repeatly installed.

@Traceur90,Sorry to reply late for Power Manager driver issue.

There is a tool from dev to log the detail of driver dection.

Could you run this tool and return back the logs files generated in the same folder?

Hello,

i let the program run, and here is the associated log file.

the second log file is after i downloaded the update again and restarted the laptop. 

Nevertheless, it will be displayed again as an update after restart.

Dev found that there is some problems of detecting the installed version. And may need time to investigate how to improve it.
