I’ve been struggling last week with my Lenovo L480.
For some strange reason it was not charging with ac adapter but it did when using the docking station.
In both cases, Windows battery icon in the taskbar was not showing that the laptop was charging but Lenovo Vantage app was showing that battery was charging.
After doing lot of things like, uninstalling ac adapter drivers from device manager, and a lot of other procedures, the one that worked for me was this one:
- Shutdown Windows (press shift key and shutdown the laptop)
- Unplug ac adapter
- Now, press and hold the power button for 30 seconds
- The computer would turn off and turn on 2 times
- Then, let the computer boot up normally
- Login to Windows
- Plugin ac adapter and…voilá!
