Another thing you could do is to try calibrate the battery, normally you can do it in Windows but sometimes windows driver update also the culprit. I've done calibration easily using Live Linux via USB flashdisk & the distro used is Ubuntu. (1) download the image from here (2) use Ventoy to create the usb installer, get it from here (3) restart your laptop, press F12 to select boot from USB flashdis (4) You should see the same language selection menu and boot options we saw in the previous ‘Boot from DVD’ step. Select the top entry, Try Ubuntu without installing, and press return, you'll boot into Live Linux Ubuntu (5) Once you boot into Live Linux, select the browser & go to this site (6) follow the installation guidefollow the command to perform calibration (7) Wait till the process is done
