This tutorial will show you how to turn on or off automatically dim keyboard backlight when in Energy Saver mode for all users in Windows 11.
Windows 11 supports automatically dimming the keyboard backlight when Energy Saver mode is enabled.
By default, this feature applies a 70% multiplier to the keyboard backlight brightness when Energy Saver is enabled.
You can change the percentage multiplier to be applied to the keyboard backlight brightness level when the system is in Energy Saver mode, on a scale from 0 (no brightness) to 100 (no dimming).
