Battery unknown remaining

Hello,

Please try these suggestions:

1. Make sure date and time are correct in Windows 10 as well as in BIOS settings.

2. Reinstall Microsoft ACPI-Compliant Control Method Battery under Device Manager with these steps

• Open Device Manager.
• Expand “Batteries” section.
• Right-click the “Microsoft ACPI-Compliant Control Method Battery” device and click “Uninstall.”
• Click the “Action” menu item and “Scan for Hardware Changes” to reinstall the driver.
• Close Device Manager.

3. Run Power troubleshooter from Settings app > Update & security > Troubleshoot

4. Update BIOS firmware to latest version.

5. If issue still persists, try replacing your battery with new one.

Hope this helps!

 

Battery not detected (Unknown remaining)

Hi,

First of all I suggest you to try with a driver remove and reinstall with Device Manager. To do so:

1. Press WINDOWS + X

2. Click on "Device Manager"

3. Click on "Battery"

4. Right click on the first element on list

5. Click on "Remove"

6. Repeat steps 4 and 5 for the second element on list

7. Click on "Detects Hardware change" (monitor icon)

Then reboot your system and check if the problem still exists.

Please tell me if the solution works.

 

How to really uninstall a Lenovo ACPI-compliant Driver

Hi everyone,

I have a Lenovo Y40, and ever since I upgraded to Win10, my PC cannot read the battery gauge correctly. After doing some research, I realized Lenovo Energy Manager and the Lenovo acpi-compliant virtual power controller driver are the problems. (I hate junkware)

I deleted Lenovo Energy Manager with no problem, but I can't get rid of the Lenovo acpi-compliant virtual power controller driver. Here are the steps I'm stuck with:

- If I go into device manager and uninstall the driver, the driver will disappear, and upon restart, it will show up again as an unknown driver.

- If I uninstall/disable this unknown driver, upon restart/hibernation, it will come back again under 'system devices' as 'Lenovo acpi-compliant virtual power controller driver', as if I didn't do anything.

When this driver is listed as unknown driver or temporarily disabled, my battery gauge issues are immediately resolved. Does anyone have any idea how to get rid of annoying drivers like this one once and for all?

Thank you!
