Battery care function not working(?)

[Bredrumb]

Hi!

So through bios,i've set the Battery Care Function to make my laptop charge up to 80% only (to preserve battery life).

But even then,my laptop still charges up to 100% (as seen through the battery meter on the bottom right of the desktop)

Is it just charged up to 100% meaning 80%/80% or is it not working properly?

If not,how do I fix it?

Hi! @Bredrumb, 

When you set the battery charging function to 80% in BIOS. The battery should only charge till 80% of its full capacity. 

So try updating the BIOS and chipset drivers on the PC to the latest version and check if it helps.

Update the BIOS using this link. Click Here

Update the chipset drivers using this link. Click Here

Try the steps recommended below.

On your keyboard, press the Windows logo key and X at the same time to open the quick-access menu.

Click Device Manager.

In Batteries section, right-click on your battery driver, commonly it’s Microsoft  ACPI-Compliant Control Method Battery. Then click Uninstall device.

Restart the PC the drivers would automatically install again.

Run Power Troubleshooter.

On Cortana, enter  Troubleshooter then select Troubleshooting.
Click Improve power usage to open the window, then click Next. 
This should run the troubleshooter, and can fix any detected issues. You may try restarting your computer and charge your battery again.

Also, Try performing a hard reset on your laptop and check if it helps.

1. Turn off the computer.

2. Remove the computer from any port replicator or docking station.

3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.

4. Unplug the AC adapter from the computer.

5. Remove the battery from the battery compartment.

6. With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.

7. Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.

8. Press the Power button to turn on the computer.

   The computer starts normally or a startup menu opens.

   NOTE: 

   If your computer does not start after pressing the Power button, then a power reset did not resolve the startup issue. SeeAdditional resources for further troubleshooting steps.

9. If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.

Lastly, try running a battery test from the F2 system diagnostics page under the component test.
