I have Lenovo G460 which has problem with charging when I plug in power cable to laptop then Power managment shows that Plug in not charging sometime battery is charged 100% but sometimes its stuck on 80% and shows Plug in not charging and does not increase to 100% and sometime its stuck also on 60% how do I solve this issue?
Charging % start and stop points can be controlled through the power management software. This is a feature can help prolong battery life by reducing unecessary charging of the battery.
To check / update these settings:
1. Click the "Settings" button.
2. Check "Optimize For Battery Runtime" under "Battery Health" and the problem will be resolved.
Optimize For Battery Runtime" is to protect the battery and extend the lifespan of the battery. Because the lifespan of one battery is related to its charging circle, the power charging will automatically cut off to protect the battery when the power reaches to a certain amount.
If the issue persists, try reinstalling the power mangement software
Uninstall Lenovo energy management re-fix the battery then charge the battery completely then restart the laptop and install Lenovo energy management software again.
