I have a SP4. As time is going by I'm getting tired of the constant bugs. The one that I'm having the most trouble with is the screen brightness. I'll turn the laptop on and the auto dim will be very dim at first, then when I adjust it adjusts the screen brightness after I adjust it so it's too bright. I finally turned the auto brightness off, but the screen still seems to adjust it's brightness anyway. It's really annoying, so is there any fix to this?
