Windows 10: Windows 10 Composite Battery Driver Missing

My Toshiba laptop was working fine until a few days ago. The predicted usage time (given by the battery icon on the taskbar) went down from 6 hours (ish) to around 1 hour. When I then put it on charge, the laptop would (after a few hours) flash a light to show me it's fully charged. Upon unplugging the laptop, the percentage that the battery was on would be 80 something %. Today I've put my laptop on and it wouldn't turn on (it was fully charged before I switched it off). I plugged the laptop in and it works while plugged in but the minute I take the charger out it dies. The battery icon says 0% Power Mode (plugged in).


Now I've been trying to figure out what's happened and the only thing that I can find that seems a bit off is that when I open device manager and click on battery, only Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery are showing. I'm pretty sure that there should also be Microsoft Composite Battery there as well.


Is there a reason for this or has this affected my laptop's battery life?

Missing composite battery driver

I was having difficulty getting Windows 10 to recognize my CPS1500AVR UPS and attempted to update the driver. Unfortunately in the process, the composite battery device and/or driver was deleted and I cannot seem to get Windows 10 to automatically reinstall
it. Scanning for hardware changes does not detect/install the battery device. Is there a way to get this device/driver restored without creating havoc in the OS (i.e. overwrite current settings and configurations). The battc.sys file is still in place,
however I do not see a compbatt.sys driver which earlier versions of Windows had. Appreciate any feedback.

Hello,

The Microsoft Composite Battery Driver doesn't affect the charging of the battery. Hardware Charging Circuit controls the charging function of the battery, it's a part of the motherboard installed in the laptop.

Microsoft Composite Battery Driver reports the information that it receives from the charging circuit. This information is displayed in the Battery Meter GUI that is located in the Desktop / Notification Area.

If you're able to see the Battery icon in the lower-right section of the task bar, that means your Microsoft Composite Battery Driver is working. We recommend that you run a check of the battery condition. Follow the steps below:

• Press Winkey+X and click the
  Command Prompt (Admin).
  
• In the command prompt window, type or copy/paste the following commands. (Note the spaces in the commands)

cd
%userprofile%\desktop> PressENTER>powercfg
-energy -output energyreport.html> Press
ENTER.

Note: Wait until the command completes (usually about 2 minutes).
This will create a file named
energyreport.html and place it on your
Desktop.

3. Open the file in your desktop> Scroll down to the
Battery: Battery Information section.

You will see:

Design Capacity xxxxx

Last Full Charge xxxxx

(Where xxxxx is a number)

Copy this section and paste it in a reply here, for analysis.

If you are getting a message: Plugged in, not charging, follow the steps below:

• Turn off the computer > Remove everything that's connected to your computer.
  
• Remove the battery > After 30 Seconds. Press and hold the Power Button on the laptop for 15 seconds.
  
• Plug everything back into the computer.
• Turn on the computer and check the results to see if the problem is resolved.

Keep us posted with the result.
