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. -- You are receiving this mail because: You are watching all bug changes.
