The auto brightness "feature" of Windows 8.x is driving me crazy. I would like to switch it off on my Lenovo W530.

  • Adaptive Brightness is disabled in Power Options
  • the Sensor Monitoring Service is stopped and disabled
  • I checked all entries in the nVidia manager but found nothing related

Has anyone managed to disable this feature from hell?

UPDATE: following the discussion in the comments, I want to make clear that I do not want to disable automatic dimming to a preset level after a given time (which is useful). I want to disable the feature which dims the screen in and out whenever there is a perceived change in the ambient luminosity, or when I open a large dark window.

Are you using Windows 8 or 8.1? What are the Dimmed Display Brightness values set to in the Power Options? –  and31415 Feb 12 at 14:34
    
@and31415: I am using 8.1. The values for "Dimmed display brightness" are 50% for each case. Does it matter for adaptive brightness? –  WoJ Feb 12 at 15:23
    
Set both to 100%. Also, make sure Dim Display After is set to 0 (never). –  and31415 Feb 12 at 15:43

@and31415: wouldn't that completely disable dimming? (I need it particularly when on battery). Dimming itself is not a problem - it is the adaptive feature which is. –  WoJ Feb 12 at 15:54
    
Sorry, I was not clear. I would like to screen to dim automatically to a preset value when not used (as it has always done) -- I do not want it to dim in and out frantically whenever there is a change in ambient luminosity, or when I open a dark window on the screen. –  WoJ Feb 12 at 16:00

I had a similar problem on my girlfriend's new laptop. You said you've checked all your Nvidia settings, but do you also have some integrated system Intel graphics? In that case, go check the Intel graphic card settings and make sure that "Power saving technology" is switched OFF! That made the job for me!

I have just one (integrated) Nvidia card. I saw various posts about the same issue with Intel cards, but unfortunately I do not have any. –  WoJ Feb 23 at 19:13
