Hello, I have the same problem. When the laptop is connected to 230V power supply it is ok. The power management module is active. When it is on the battery and after a few minutes of inactivity the screen brightness reduces to a minimum, there is no way to brighten the screen again, and the power management module is not active. On HDMI output the picture works "normally". My laptop is a Lenovo G50-80.
Your issue is probably something different. Please submit a new bug report for it. In general, it's best to do this rather than re-opening an old one that looks like it might be reporting the same or similar symptoms. Thanks!
For a test I installed XFCE. There, too, is a problem with turning off the screen on battery. That is, it is not the cause in KDE. Greetings
