LinkBrightness

Windows remembers your laptop’s brightness setting when it is running on battery or connected to a power source. However, any manual adjustments you make are only applied to one of these power plans, so you need to change the setting again whenever you connect or disconnect the charger.

LinkBrightness is an open-source utility that can help you out in this scenario. It monitors all brightness changes and updates both of your power plans while running in the background.

This application is designed to make the life of laptop users easier, especially those who frequently make small brightness adjustments and don’t want to perform the same action again when connecting or unplugging a charger.

It can run in a console window or be hidden in the system tray, and it continuously monitors the current system brightness in order to update the setting for both power plans.

When launched without any additional parameters, the program runs in a console window and can only be minimized. However, you can also configure it to be sent to the system tray when minimized, as well as immediately upon launch.

The simplest way to set everything up is to create a shortcut to the executable file and add one or both of the launch parameters (/hide_on_start and /hide_on_minimize) in the target field. This shortcut can then be copied to the startup folder if you want the program to be launched with windows automatically.

On the whole, LinkBrightness does its job well, but it isn’t the most polished piece of software out there. It lacks a GUI and may be a bit confusing for novices, but it works great once you have performed the initial configurations.
