Sony :: SR Fn+F5/F6 Brightness In Windows 7
Mar 7, 2009
I just tried out the Windows 7 beta on my SR 220J/B and everything seems to work great except for the Fn+F5/F6 brightness controls.
Win7 seemed to work well out of the box, and I've installed the Alps and Synaptics drivers, along with the Upek fingerprint software (btw, I can't log in to Windows using my fingerprint, even though the log-in screen has the fingerprint icon...). I also installed "Vaio Event Service 2 (4.2.1.12090) -- All OS" from the Drivers & Software post, and the volume/mute Fn key controls work, but not the brightness.
How can I get Fn+F5/F6 to work?

I upgraded from Vista to Windows 7 on my SZ5. Was surprised at how much works out of the box (fingerprint sensor, drivers etc) but the one glaring bug I found is that when I close the lid and the monitor shuts off, when I reopen it the brightness controls (FN+F5 and FN+F6) no longer work.
I also notice that the brightness controls in Windows' power options Control Panel disappears.
I need to restart my computer to resolve this (similar problems by other users: Sony Vaio SZ1XP - Windows 7 RC ). Does anyone have a solution? Thanks!

I recently upgraded by Windows Vista 32bit business VaioZ690C Laptop to windows 7 professional. So far, everything has worked out great, but I have a couple questions:
1) How do I get my brightness keys to work? I cannot increase / decrease it
2) When I installed Windows 7, many of the Windows Vista drivers rolled right onto Windows 7, and would absolutely perfectly, do I still need to uninstall them all and install the "windows 7 version" or is this fine.
extra info:
*running R3054M3 bios ("I THINK")*
*running v.5 of vaio event service(i think something like that*

I've recently installed Windows 7 x64 build 7229 on my Vaio and I've managed to get everything working except for the screen brightness controls.
So far I've installed the x64 version of SFEP driver along with Vista versions of Sony utilities dll, sony shared library, sony event service and sony settings utility.
Installing the xp versions of those programs made the brightness control work fine, but on Windows 7, the screen brightness control pops up on the screen but the brightness doesn't change. Also I've read that I should be able to control the brightness in the Windows mobility manager, but there is nothing there about screen brightness.
The screen running at full brightness is hurting my eyes.

just can't seem to get my Brightness controls to work in speed mode in windows 7.
I've tried 169.09, 180.70 and the most recent forceware drivers.
I've installed the registry file that was recommended in one thread.
I've tried all kinds of orders. Still, nothing.
I've currently installed (in this order)
SPEF
SonyPI
Shared Library
SonyUtils DLL
Event Service
The Registry Patch
NVIDIA Drivers
They work fine in STAMINA, but not in SPEED. I can't even access them through Windows Mobility Center or Power Options. I can change them a very small amount though the NVIDIA control panel through the "adjust color settings" tab. Otherwise, theres no mobility options in the NVIDIA panel.

Just installed Windows 7 on my E4300. This is the first time I'm trying out an OS other than XP (never touched Vista)
Most of the components seem to work well.
Can anyone tell me if they got the screen brightness (Fn + up, down or left arrows) to work? I can see the toggle on the screen move from left to right in the settings, but the actual screen doesn't actually go dim or bright.
When I pull the power and run on batt, the screen dims (and I cannot make it brighter). And if it's on power, I cannot dim it either.
Is this a driver issue? Which driver? The closest one I see is the Video driver.
Also, does anyone also notice the mouse pad being sluggish?
I'm so used to very fast mouse where if I move my finger from the top right to the bottom left, the mouse arrow also does the same on the screen in one shot.

I have upgraded to W7 pro, ran the companion DVD and everything is good except the FN brightness key (also changing brightness in W7 itself) they don't work.
I have been to the sonystyle.ca website and down loaded apparently the correct utility settings driver 5.0.0.07280 for W7 Pro 32-bit (at least it says on the website its compatable) and when I try to run it, it says it's for Vista only.

I have had this computer for about 9 months and just recently have been unable to adjust the screen brightness. I have had this problem for a couple weeks and have installed all available updates and restarted the computer. I could not find any relevant information on this issue. My product is in warranty until December ....

I had lenovo g500s recently with windows8 64bit preloaded. I got bored from windows8 and downgraded to windows7 home premium 64bit (a difficult procedure by the way)....
Windows 7 worked very fine after installing the device drivers, except for the LCD brightness that doesnt respond to any fine adjustments...
In the main page of windows power management, as well as the keyboard hotkeys, the slider either goes to the maximum or minimum brightness (no stages in between though in windows 8 there were > 6 stages)....
In the advanced settings screen, as far as i adjust brightness (for example to 50% on battery, 70% plugged in) this doesnt lead to any change in the brightness practically....

This auto brightness problem is been bothering me for a long time now, and i can't find any fix for it at all. The display goes:
- Bright when having on screen a white web page, document, picture
- and it display dims down when having on screen a dark web page/ document or picture
Note 1: I changed the settings and Turn off Auto Brightness in windows 8 advanced power plan settings .
Note 2: I tried to go disable the AMD Vari-Bright but the windows 8 AMD catalyse control center, but it doesn't have that option to turn in off .
Note 3: I did disable the Sensor Monitoring Service in services.msc menu .. but still didn't do the trick :/
Note 4: I did disabled Intel Display Power saving Technology in intel's graphic and media Control Panel and .. with all this, still, the auto brightness problem isn't solved :/
Now .. what to do, with all this attempts and still can't get rid of it, i start losing hope i can use my laptop without the screen changing brightness on its own, watching a movie and browsing the web with the screen flickers to adapter to the background....

I've done a search and couldn't find anything relevant.
My FZ of 28 months old has suddenly started making a faint buzzing noise from the screen.
At first I thought it was the fan, but I realized it's the LCD. I can't change the brightness for some reason using Windows 7 but it's on Max Bright. I've seen some threads of people having this problem on lowered brightness levels but this is happening on full.
When I shut the lid, the buzzing stops. It can be heard if I stand behind the laptop or place my ear beside either rear corner of the laptop.

I just installed a fresh copy of Windows 7 on my Sony VPCF115FM laptop, and I was wondering what I need to install to get the brightness control to work. I already tried the video drivers, shared library, and notebook utilities from this site:

But nothing seems to affect the brightness, even though I do see the brightness bar now when I press the appropriate keys.

I did a clean install of Windows 7. I did not load all that crap from the 2nd CD.I am trying to determine which Drivers I need to install.
I installed the VAIO Event Service and Sony Shared Library.
What is strange is, when I click on the FN button and press the increase brightness key, the brightness meter does appear on the screen, but it will not go above the lowest setting.

i am using my TT in the dark, once i turn the lights off in my room, the screen becomes dim. So it kinda makes it hard to see the keyboard. So i have to turn the lights on so i can see it clearly, how can i prevent this?
I have checked the power plan and i have all of them set up to maximum brightness. I just want the screen to remain as bright as it does when the lights are on. It was dim when i purchased my TT a few months back. Then i did a restore and it was cool. Then i did another restore and it went back to being dim. This was even though the restores when done were the exact same to a tee. I didn't mess with any settings.

I just got a z11 and will be returning my macbook pro soon.
The only thing that is making me hesitant is the screen brightness of the z. With the plug in and full brightness, it's not that bright, at least NO WHERE NEAR as bright as the macbook pro with high res anti-glare. Is this normal?
How many of you Z owners find the screen brightness too low? Even at full, it feels dim.

As of 3 days ago I deleted the Sony Event Service from my Vaio FW and now the volume indicator doesn't show up nor does it work when I press the function button along with F5 or F6 for brightness.
I installed the Event Service again and I am thoroughly stumped.
Fixed it myself XD

The brightness on my new E545 with Windows 8.1 fluctuates weirdly while browsing the web or doing other this. This is really annoying. It will fade and then suddly flash to a brighter setting.
I already disabled the adaptive brightness in the power options and it still does it.Searching around the web I see a bunch of suggestions that are related to Intel graphics adapters but nothing related to AMD.

I will keep this short, I have a Lenovo ideapad y510p with Windows 8.1 (I got it with 8.1, did not upgrade from 8) . I noticed a problem yesterday, where I cannot adjust the screen brightness. If I use the keyboard commands (Fn + Up and Fn + Down) The slider appears on the top left of the screen, as always, but does not “slide” It stays static.
If I move the slider on the Setting menu, I can slide the value but the brightness does not change and the value is not reflected on the slider on the top left of the screen.
I am not sure when this happened for the first time.

This is almost a classic problem. I just installed XP SP3 on a Vaio G11. I did everything according to Sony's plan. But the brightness keys don't work.
Is there a chance that Sony's drivers were written for XP SP2, and that SP3 is the cause of my problems?
Reason I'm thinking this is that SP3 recognized some devices that SP2 doesn't recognize
