Display keeps dimming after I make it higher


I have recently upgraded my laptop to Windows 10, since this upgrade, everytime i manually put the brightness higher, it automatically dimms back to around 10%. I have tried everything in the settings, in the power options, and even turned off the adaptive brightness option. If there are any other solutions this would be great to know! as its getting very annoying.

If you have a Sony Vaio the following link may be of use.

Also this link may be of benefit

Apologies if you already know about the above

Update (10/12/2015)


Firstly, I assume that you tried the following "fix" which was in the first link I sent and it didn't work

Launch VAIO Control Center (Windows Key + Q then type in VAIO control center)

Under Display uncheck adjust brightness settings automatically

Reboot your machine

Did you go to the Sony support page and find out info about driver updates for your particular model? I was only generalising when updates might be available because I didn't know your exact model or OS.

So your options as I see it are:

1. Find out how long before Sony provides driver updates and wait until then, if you can put up with it that is.

2. If you can't put up with it roll back to Win 7 (as long as the 30 day expiry period in still valid). If it has been more than 30 days unfortunately you can't roll back. You can always go back to Win 7 after the 30 days with a fresh install but that would be rather extreme.

It is my understanding that you can roll back to Win 7 if within the 30 days and then still upgrade to Win 10 later on, when drivers are available, at no cost. My info on this might be wrong and you should double check.

Win 7 is still being supported until 14.1.2020 so it is not that it is disappearing anytime soon.

If you like Win 10 you might want to hang in there (if Sony comes thru soon), after all it is Microsoft's latest OS and after the debacle of Win 8 I'm sure that it will be a good OS. History seems to show that they get every 2nd OS right. (Win98+, Win Me-, Win XP+, Vista-, Win7+, Win8-)

Ok, firstly thanks for your help.

So would you recommend to just deal with it and then wait for them to release a new update for the display drivers (I am a little out of touch with computers these days).

Also I don't know if this is relevant but I have upgraded from windows 7 ( I have checked the compatibility on whether to upgrade, the laptop was a high standard when it was purchased).
