How to switch off auto brightness on a Lenovo W530

Question

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.

Solution

Yup, I know what you mean, and I did a search on my X220 before, here is the soluation:

Uncheck Display Power Saving Technology in Intel Graphic and Media Control Panel then you are good to go

Are you using Windows 8 or 8.1? What are the Dimmed Display Brightness values set to in the Power Options?

@and31415: I am using 8.1. The values for "Dimmed display brightness" are 50% for each case. Does it matter for adaptive brightness?

[and31415]

Set both to 100%. Also, make sure Dim Display After is set to 0 (never).

@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.

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.

Thank you! You saved me a ton of frustration! On my 2017, Win 10 Thinkpad, you can find it by searching for Intel® Graphics Settings.

This should be the accepted answer.
