Public bug reported:
I have a Lenovo E495 CPU, Ryzen 3500U, and Vega 8 GPU.
Bug: I plugged in the charger and clicked suspend. When I woke up my laptop, it
had 0% battery.
How did I fix it? In BIOS I disabled my battery and waited 2 minutes. The
charger was disconnected when I disabled the battery.
After that I turned on my laptop, and the battery % was 95%.
Before I disabled the battery when I plugged in the charger the charging light
was white, indicating that the battery is fully charged, but Linux said 0%
battery.
I have set up charging threshold: stop charging at 95% start at 85%.
