Re: Cannot adjust brightness in new Windows 10 Update

I thought I replied to a particular posting - not the whole thread. What, after 2 hours of poking around, turned out to be a simple and total solution was to open the Device Manager and enable the built-in screen, which for some reason had been disabled by the Windows 10 update. Then the F6-key (Brightness+) started working normally again and the screen got bright.

OK, I'll boot up my Win 8.1 Flip, reinstall the latest Intel Graphics driver, reboot, get the dim screen, go into Device Manager, Monitor, and see if my monitor is disabled.

 

Thanks.

Re: Cannot adjust brightness in new Windows 10 Update

Hi Guys,

 

I don't own the same model as you, but my  SVE14A27CXH presented the same issue ( brightness control not working after updating to win 10.)

 

What I did was download the new VGA graphics driver for windows 10. (I have a AMD+intel hybrid graphics).

 

I'd like to suggest the same for you. Just go for intel website and look for the intel driver update utility, run it, and maybe there is a new driver for windows 10.

 

good luck with your laptops!

Re: Cannot adjust brightness in new Windows 10 Update

I've been dealing with this ever since I upgraded to Windows 10. My laptop is a VPCSA290X. I finally (seem) to have found a solution. 

 

Open Vaio Control Center

Click into Display settings

Click into Automatic Brightness Settings

Uncheck the box next to Adjust Brightness Automatically.

Hit Apply.

 

Hope it works for you too.

Re: Cannot adjust brightness in new Windows 10 Update

Great! This worked for me as well!

 

I first had to run Regedit.exe and then edit the registry key Feature Test Control in

HKEY LOCAL MACHINE\SYSTEM\ControlSet001\Control\Class{4d36e968-e325-11ce-bfc1-08002be10318}\0000 (or 0001)

I set the value to 0x0000fb20 (64288). 

 

Finally, when I checked at Display Adapter on Device Manager, It showed as enable. Then I disabled it and enabled again.

 

Screen brightness works fine now. The same as before the Win 10 Update.

Re: Cannot adjust brightness in new Windows 10 Update

I did below changes, it worked fine for me.

 

Step-1> go to 'Vaio Control Center'

Step-2> Click on "Image Quality"

Step-3> Check 'Display Brightness' section in right side. Turm this Off if you don't want your vaio machine to automatically adjust broghtness for you.

Re: Cannot adjust brightness in new Windows 10 Update

You have to turn off "Adaptive Brightness" in the Advanced Power Options.

Control Panel  >> Power Options >> Change  Plan Settings >> Advanced Power Options >> Display  >>
Enable Adaptive Brightness (Turn Off)

Then you can set your desired brightness in "Display Brightness" under Display in Advanced Power Options.
OR by using the slider accompanying your chosen power plan.

OR access these settings from START>> Settings >> Power and Sleep >> Additional Power Settings >>

Re: Cannot adjust brightness in new Windows 10 Update

Did anyone pinpoint the sony driver necessary to re-enable brightness control in Windows 10? Other solutions don't apply to my vpcl116fx.

 

- In REGEDIT I don't have Feature Test Control. I do have Feature Control and Feature Score.

- My display adapter is enabled, with the latest 341.95 version for my NVIDIA GeForce GT 240M.

- Monitor is Enabled using a Microsoft Driver Digital Flat Panel (1920 x 1080 60Hz).

- I do not have Vaio Control Center installed

- Control Panel "Adaptive Brightness" is off.

 

Or, does anyone know of a different possible solution?

Re: Cannot adjust brightness in new Windows 10 Update

Hello
This just worked for my VAIO VPCS111FM on windows 10
I found it in here:
 
AaronAlexander replied on 

Hello everyone.  I had figured this out earlier for the VCPS111FM with Win8 beta.  After reinstalling full Windows 8, it took me about 3 hours to figure it out again but I finally got it.

 

1.  go to http://esupport.sony.com/US/p/swu-download.pl?mdl=VPCS111FM&upd_id=7237&os_group_id=6

 

2.  Download Vaio Care

 

3.  Once this is installed, open Vaio Care and click on Advanced Tools

 

4.  Click on Restore and Recovery

 

5.  Click Reinstall applications and drivers

 

6.  You should receive a popup "Recovery partition has a different operating system.  Are you sure you want to continue?" - Click Yes

 

7.  Click next

 

8.  Scroll down and click the check box next to Graphics Driver (Intel)

 

9.  Click Next

 

10.  Click Start reinstall

 

This should fix the issue as it did for me (without a reboot you should immediately see the brightness increase).

 

Good luck!
