Hello!

Two days ago I've bought new laptop, ACER Aspire 3, AMD Ryzen 5 + VEGA 8. Today I've found problem - when I am working only with battery power supply, I am not able to see anything - backlight is turned off, but when I plug a charger, light appears. What's more, when I have plugged charger to laptop and I decrease brightness below 50%, backlight is turning off. Above this value backlight is turned on with full power, there is not possibility to regulate it.

I've noticed, that when I am working with turned off "Microsoft ACPI-Compliant Control Method Battery" the backlight works without plugged in charger, but still there is a problem, when the brightness is below 50%. I've been checked power options, but nothing has bring me any solution.
