I often change power plan or (dis)connect the power cord depending on what I do with my laptop and where I am. Every time I do so, the display brightness changes into whatever it was last time I had the same power plan and AC power status.
The display brightness has nothing to do with those settings. I adjust it manually to what I feel comfortable with in the current environment, and it's frustrating having it changed by some automatic setting that gets it wrong every time.
I'm in a dark room, getting ready to watch a movie or something, everything set perfectly. Oh right, the power cord. Boom, instant 20% to 100% flash that kills my eyes. Thanks Microsoft...
How do I disable this automatic adjusting and get full control over the brightness?
