Yoga 2 Pro - Auto brightness feature and how to disable in Windows 8.1

Question

I have a Yoga 2 Pro system and the brightness on my screen is constantly adjusting.  This  is most obvious when making the move from the desktop to Metro. After hitting the windows key, I can see the brightness increasing in stages (about 4 times) after flipping over to Metro.

 

I have disabled Auto-Brightness under the Change My PC Setting -> Power and Sleep menu. I have also disabled Enable Adpative Brightness under Windows Power Mangement but the issue still persists.

 

Is there any other location I might be missing a setting that can be affecting this ? Brightness is set to full and keeps dipping down.

Answer

There are a few factors if your screen appears dim, or the brightness changes automatically and frequently.

 

You can check the three methods below to ensure the auto brightness adjustment feature is not enabled.

 

1) Brightness adjustment via Power and Sleep in Windows 8.1

You may wish to disable the Automatic Brightness setting in Windows 8.1.  This setting is enabled by default; however, some users may not wish to make use of this option.

 

To disable Automatic Brightness:

 

First, begin by swiping the right edge of the screen or touchpad to fly out the Charms bar


Next, tap 'Settings'


Now, in the bottom right corner, tap “Change PC Settings”

In PC Settings, tap "PC and devices"

Under "PC and devices", tap "Power and Sleep".   The Brightness setting allows you to toggle the automatic brightness feature on and off.  Simply drag the slide controll to the left to turn off.

2) Check your Intel graphic card properties

If you find that your screen continues to automatically adjust brightness, please try the following:

 

  1. Right click on the desktop and select "intel graphics properties." 
  2. Now, select the "on battery" tab and turn off "Display Power Saving Technology."  

 

This method was provided by user Supermax .

 

3) Check you Power Plan set in Power Option in Windows 8.1

 

Right click start menu in Desktop and choose Power Options.

Depends on the power plan you're using, select the "Change plan settings".

Set all the brightness according to your preference under "On battery" and "Plugged in" mode.

I have the Lynx with the same issue. None of this works for me. The intel power option does not appear to on my system.

I noticed the problem seems to only occur When the tablet is charging and then when the fluctuation seems to happen when its fully charge and the power light flashes to recharge again is almost a direct correlation. Is any one seeing this?

For me I solved it via classic "Control Panel"

Control Panel\System and Security\Power Options\Edit Plan Settings

Change advanced power settings

> Display > Enable Adaptive Brightness > OFF

 

cheers

 The settings mentioned in this article was not available for me (due to domain policy / GPO)

I've been fighting this issue for a few rounds. By the time I arrived to the main solution suggested by this article, the option to turn off automatic brightness was disabled, perhaps because I'd adjusted the brightness settings via the traditional Windows menus to 100% and to never, ever dim.

 

I thought I'd conquered it, but tonight after a while on battery, it started to dim again. I also went to the classic "Control Panel":

 

Control Panel\System and Security\Power Options\Edit Plan Settings

Change advanced power settings

 

> Display > Display Brightness

>On battery: 100%

>On power: 100%

 

AND

Dimmed Display Brightnes

>On battery: 100%

>On power: 100%

 

AND

Enable Adaptive Brightness 

>On battery: OFF

>On power: OFF

None have worked for me but found a solution.

FOR THOSE WHO HAVE WINDOWS 8.1 AND HAVE THE IDEAPAD FLEX SERIE:

(I'm not sure if this will work for others as well, try it..)

 

1) Follow the above instructions at the top

2) If it's still a problem, simply right click on the desktop

3) Selet the first option, which should be your processor's control center. 

4) Click Power > PowerPlay (could be different, I'm not sure but this option is where you edit what your processor does when on battery)

5) Simply check off Enabled VariBright which should be at the left of the adjustment screen brightness bar.

 

THEN YOU'RE DONE.

This one worked for me.

 

Apparrenly the culprit is the Intel Graphics Card and upon tinkering with the options. I think I've got it.

 

First I disabled the adaptive brightness on the power options, and disabled the brightness sensor on the "services.msc"

 

*Then I right clicked on the desktop.

*Clicked on " Graphics Properties"

*Clicked on Power.

*Then Disabled the "Display Power Saving Technology"

*Then clicked APPLY.

 

Now my display is not automatically dimming anymore. :smileyhappy:
