If you’ve ever encountered this issue where you have your indicator saying that your batteries are plugged in, not charging and you have a Lenovo device, it may very well be not a bug, but a feature. When i noticed this on my Helix, I googled and found a few solutions suggesting to uninstall, reinstall software, drivers, etc.
The simple “fix” i found was to go to the “Lenovo Settings” app –> Power –> Battery Health Mode
Most likely it is set to “Automatically optimize for battery life”. If you set it to Always fully charge, then you should see your power indicator charging again. As described in the tool, it’s recommended to use the option to optimize for battery life if you are always using your PC with AC power and the battery charge is 100%.
