hi!

I have a Win8.1 computer with 2 batteries. If I have both batteries inserted at powerup, Windows shows me the percentage of both batteries. If I Change one of the batteries, the percentage is updated --> everything okay.

But if I remove one of the batteries, the percentage will not be updated. The display does not change to"not available".

If I insert only one battery at powerup, Windows shows me "not available" for the missing battery --> okay. But if I insert a second battery, the Display doesn't change to show a percentage.

The only way to update the display is to start the device Manager, select the Microsoft ACPI-Compliant Control Method Battery, disable it and enable it again.

Is there any way to make Windows update the without this trick???

 thank you in advance!

Hallo Brandon,

thanks for your answer. the system is a MI/O Extension Single Board Computer. A MIO-2264 from Advantech. Both batteries are notebook batteries, no backup batteries.

windows correctly loads the ACPI driver for both batteries and the BIOS reads the batteries correctly. When I read the battery information from my application - using Win32_Battery WMI class - I can read the information correctly.

Only the information in the taskbar is wrong:

If I change the battery, the information in the taskbar is okay. But if I remove one of the batteries, the information stays on the old status until I insert a new battery.

In the meantime I have a second question: Is it possible to show 2 battery-symbols in the taskbar? One symbol for every battery, not a single one for both batteries?

I hope, I was able to explain it....
Astrid
