the screen on my mac m1 airbook keeps automatically diminishing ...why?

[wfriedwald]

darndest problem ever!

The screen on my M1 Macbook air (c2020) keeps turning itself off ... I have another monitor attached and that stays at full brightness - but I can't figure out why the built in screen on the macbook air keeps diminishing ...

I have AUTOMATICALLY ADJUST BRIGHTNESS turned off!

darned annoying! Does anybody have a suggestion? Grateful for all feedback!

There's a difference between dimming and turning off. Which one are you talking about?

it dims ... very quickly ... all of a sudden it gets dimmer and dimmer and within about 5 seconds, the screen is completely black. but it doesn't turn off all at once, it dims.. !

thanks for any suggestions!

I don't have a macbook but surely just like the iPhone and iPad there's a time-out function where you can adjust the time before the display goes to sleep. Try Googling it.

PS: is there any way to LOCK the display brightness so that it won't change?? this is maddening!

(and to further clarify, it does NOT turn on the lock screen, it just dims down to totally blackness... if that's even a word!)

I have no idea if this will help but have you looked under 'lock screen'
There's a setting there 'turn display off on battery when inactive'.
What they mean by inactive is nothing is happening, like you aren't typing on it, using the curser or a video playing.
It definitely affects the whole computer not just the lock screen.
On mine, if I have it set to 1 minute it will annoyingly dim the screen after 1 minute if I'm just looking at something, so it's almost black but I think it eventually does shut the screen off.
Try setting it to never and see if that fixes it.
Otherwise it might be something in accessibility.

I was thinking about that, but as you say, why would that affect just one of the two screens currently turned on? Wouldn't that automatically turn off both screens?

thanks for feedback!
