Windows 10: How to disable Brightness change when plugging in or unplugging power cord?

I absolutely hate the automatic brightness change that occurs when I plug in or unplug my power cord. How can I disable this?!

:)

 

Plugging in power cord turns off screen in Windows 10. Please Help!

You can control the brightness separately for "battery" versus "plugged in". And it sounds like the "while plugged in" brightness is set to 0%.

Here's what I'd do:

• Type "Power Options" in your Search box
• Next to your current power plan, click the blue "change plan settings" link
• Under the "plugged in" side, drag the slider up to increase the brightness for while the cord is plugged in.
• Be sure to click Save Changes when done

After that, try plugging it in again.

Is Adaptive Brightness disabled?

 

Screen goes black when I plug in the power cord since installing windows 10

This worked for me. It seems that, for some reason, when the power cord is plugged in, the screen brightness can't be set on maximum for whatever reason. I changed the brightness setting to just below max and it worked fine, with the side effect of the
screen dimming when I plug in the cord and brightening when I'm on battery. If I use the fn+brightness key to manually change the brightness to max, the screen shuts off again.
