I have x220 with Win10 on it (BIOS 1.43). Suddenly I noticed that battery icon is not changed after I disconnected the charger, it still shows charger is connected and battery still charging... But battery of course discharging.
I tried to remove the battery and laptop working fine via charger only.
It works ok without charger if battery is charged, but icon always shows that laptop is conneted to charger.
Also there is no sound when charger disconnected. (Sound is switched on in BIOS)
My battery is not new but correctly charging on other X220.
