When gaming on battery power, display brightness automatically decreases to the minimum value in Windows. High performance power profile, all screen dimming options disabled, already tried alternative display drivers and a full system restore.
could you please tell us what kind of Dell Laptop and operating system you are using?
Has your system got function keys on the keyboard to increase or dim the brightness?
