Windows 10 : Battery Unknow remaining

I have issue of Windows 10 battery “Unknow remaining” status.

Cause :

I though this issue occurred after notebook went to sleep.

Solution:

Step 1 – Uninstall driver of battery in device manager

Step 2 – Check and repaired system files using “sfc /scannow” (need to run cmd with Run As Administrator”)

Step 3 – Unplug and run notebook until battery empty and off itself

Step 4 – Waiting for 10 minute to make sure battery is cool down enough to extend its life. Then plugin power to notebook and start

My notebook is working fine again.
