Oddly enough, I had similar with my old laptop, that went haywire after updates, and although the green light was on the charger, it stopped charging/operating
In the main, mine was always plugged in when used so battery didn't go down every time.
It did run for a bit in safe mode, before it stopped charging, but I got the arse with it, bought a tablet and smashed the laptop into oblivion in the yard. BFH job !!
That was a great feeling, and funny enough calmed me down to be done with all that shit,
I think that Android geezer and his mates are programmed by the government to f... us up !
