Helix 2nd - ultrabook keyboard not charging the tablet when unplugged from AC

2018-01-13, 15:53 PM


I noticed that my ultrabook pro keyboard isn't replenishing Helix 2nd (20CG) battery any more when unplugged from AC. While not essential, it was still useful feature to go trough the long day of use.

Other than that everything is working as it should (Keyboard battery draining 1st, tablet 2nd, and when on AC it charges the other way around: tablet 1st, keyboard 2nd). 

I tried (re)installing all battery management & drivers in Windows 10 environment, also updated keyboard firmware, battery firmware shows 'no upgrade needed). Lenovo vantage app is also showing that everything is OK with battery, and fiddling with power settings there shows it communicates with batteries well (start charging or stop charging at certain percentage).

Also tried reseting the keyboard part with a pin, but I'm not sure if I did anything (no  leds blinknig, nothing really seems to be happening).


Any ideas?
