Abrupt shutdown despite charge
I have an Aspire E5-575, and I've had it for about two years. It completely shut down, unprompted, despite being about 85% charged. At the time I was playing a YouTube video, and had Spotify and a Word doc open, but nothing else. It just cut all audio and visual and shut down, and I couldn't turn it back on until I'd plugged in the charger for a minute or two, as if it had completely run out of battery power. There was no update/restart scheduled or anything, and a scan I performed after getting it rebooted didn't yield any issues or threats. Has anyone else had this problem, and if so, what caused it and how do I ensure it doesn't happen again?
