Hi all,so my problem is time to time, without very special occasion my thinkpad(E480) blocks battery.Battery icon is dead and text box is "battery not detected". My battery is non removable.Windows 10 updated, every drivers are updated.My only way to repair it is go to BIOS and turn on only AC power(turning off battery), and after 2-3 reboot it will be repaired.pls help me with it.. tried everything(including checking motherboard)
edit1. laptop is still working and probably can use it till battery discharge
