I have a Vaio Z, model is VGN-Z12GN.
I upgraded from the pre-installed Windows Vista to Windows 7 Professional (new, up-to-date legit copy from MSDNAA, no pre-release version).
When I am in Speed mode, I can not adjust the screen brightness by using Fn+F5 and Fn+F6. I really would like to have this functionality back again .....
I've just installed Windows 7 Ultimate 64bit on my Vaio Z11MNB. As Google told me there is a problem with the FN + F5/F6 brightness adjust in speed mode.
All Sony software ist installed correctly and in the newest version I found.
As in many threads mentioned I followed the right order. But I still cannot adjust the brightness in speed mode
This thread Problem with Vaio Z Windows 7 brightness lead me to the right graphic drivers I thougt... Okay these drivers[url] are for the ZD790 but this shouldn't matter it's the same 9300GS chipset...
The following sony software is installed:
SETTING_UTILITY_SERIES_5.1_5.1.0.11200
SFEP_DRIVER_SONY_8.0_10Q1_O_7_8.0.1.1
SPIC_DRIVER_8.0_09Q3_7_8.0.1.1
SONY_SHARED_LIBRARY_5.5_5.5.0.10160
VAIO_CONTROL_CENTER_4.1_4.1.0.10160
VAIO_EVENT_SERVICE_5.1FH_5.1.0.12010
VAIO_POWER_MANAGEMENT_5.0_5.0.0.11300
VAIO_SMART_NETWORK_3.1_3.1.0.11250
Another smaller problem: From time to time there is a yellow exclamation mark at the SD-Hostcontroller in the device manager. I've googled a lot but there seems to be no other driver than the windows included. VEN_1180&DEV_0822
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.
I just installed Win7, sticking as much as possible to this method:
VAIO FW Clean Windows 7 Install Guide
everything's working, all FN keys, volume multimedia zoom LCD out,
all but brightness.
problem is, using the FN keys, the brightness dialog is showing, but I can't increase or decrease it. brightness does not show up on power managment nor on mobilty center. the power plans from vaio ("VAIO optimized") are showing, but still if I pull the plug screen stays on maximum brightness...
I can run in safe mode and in stamina mode all day long, however when I switch to Speed mode after a few secs the screen goes black and the notebook just turns off. Anyone have any ideas? I am at a total loss. I have tried a complete restore and also tried Natius drivers.
View 7 Replies View RelatedIt seems for some reason my Z690 does not work well in the speed setting. This results into videos that seem to refresh a lot, games that are slow and have jagged edges and in general slow video performance.
Whats funny is that on stamina setting, all my graphics actually do quite well. Videos play fine as do the games /w smooth edges
I have a VAIO VGN-SZ55GN but I found out that I can't switch between speed/stamina mode.
I had had the intel graphic driver installed automatically after I'd installed a new OS onto the laptop but I can't get the nVidia driver to work.
I tried shutting down the laptop, moved the switch to speed and turned on the laptop again but I still can't get the laptop started up w/ nVidia graphic card.
I can't seem to change the brightness level in Speed Mode, be it through Fn keys or Power Option on the laptop. I've tried disabling UAC and running VESMgr.exe and VESMgrSub.exe as administrators. And still can't alter the brightness level. Everything else works, just the brightness option won't work in Speed Mode. Stamina Mode works flawlessly, giving me the option the change the brightness level how I want.
View 10 Replies View RelatedI have a Sony Vaio VGN-Z590 with windows 7 32 bit professional installed. When I switch to speed mode and hook up a monitor (24" dell LCD) via HDMI->DVI the graphics card temperature goes up to around 80-95C (measured with real temp 3.40) and the CPU temp also goes up into the 60-70s. No programs are using the CPU heavily. During this process the fans go up to max and the computer gets really loud. I have all the latest drivers installed and the latest BIOS.
I was wondering if anyone else has a problem like this? Would installing 64 bit windows 7 be better? It makes it really noisy when I hook up a monitor via HDMI. Any ideas?
Everything is perfect in stamina mode, low temps, low cpu usage.
my laptop,VGN-Z720D/B, can't switch to speed mode without restarting computer, which means I need to switch mode by turning off or restarting the laptop, I updated the BIOS and graphic drivers and reinstalled the whole OS by using recovery disc, it still doesn't work. Is it possible the hardware problem?

I can not use Virtual PC because, although the CPU has VT support, Sony did purposely not include the option to enable it in the BIOS (a well known issue).
Are there any options to get Virtual PC running on my laptop (maybe an older version or a workaround)? Or are there any *free* alternatives to Virtual PC which will run on Win 7 even without VT being enabled? Any options?
How can I have a virtual PC running in Win 7 on a Vaio Z12?
I tried everything I could but am not able to adjust the brightness of my laptop (i.e. HP 250 G2 Notebook).
View 5 Replies View RelatedFor some reason the brightness on my lcd isn't adjustable. It's stuck at full brightness, on battery, on power, doesn't matter. I've had this laptop for about 2 weeks now. When I first got it, the brightness levels were working, but now they are not. OS is Windows 7 Home.
FN - Brightness Down brings up a on screen display showing the brightness level at full and goes down by about 1, though I see no different in the brightness. It doesn't matter how many times I press the button, it never goes down more than 1.
Control Panel -> Display -> Adjust Brightness -> Power Options: The slider at the bottom shows the brightness level at lowest setting. The FN - Brightness adjustment will move this slider up / down on the scale, but there is no change in the screen brightness.
Anyone have any ideas as to why I can not adjust the brightness and how I can get it back to where I can adjust it?
just brought acer aspire 4937G to replace my dead 5584(which the graphics card dead). so reinstall XP from old laptop to new one.
before i install the graphics driver, i'm able to adjust the brightness. but after i install the driver(latest from acer), i totally cannot adjust the brightness. is either very dim, or very bright.
i tried getting latest driver from nvidia, but during setup, only HD audio, dont have any display driver to install.
Is there a way to adjust the brightness control on a Inspiron 13, 2 in 1, while in tablet mode?
I know how to adjust it using the keyboard in laptop mode but not in tablet mode.
Another problem on my Lenovo Thinkpad L520: After installing the Lenovo Power Management Driver, I can no longer adjust the LCD brightness by using the FN+DEL/POS1 keys. Immediately after adjusting the brightness, it gets reverted to its old value, set in the Power Management software.
I tried the Windows 7 driver (1.65.05.21) and the WIndows XP/7/8 driver (1.66.0.22), both with the same result.
This is really annoying and I am very frustrated with Lenovo right now, since this is not the only problem I am having with the laptop.
How can I adjust the brightness of my screen? I tried using f2 and f3 but no changes. HP 15-d024se.

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 ....

My computer is HP ENVY 15-j175nr and my product numer is F7Q25PA#AB4.
it's that friggin electric sound when you adjust your screen's brightness. Not that the sound is loud or anything but it's so annoying. Even clean install of mac os didn't help.
And it's not the hard drive that's making the noise. It seems to be coming from top left corner. Blackbook is half a year old and it started to emit that friggin noise a month ago. So did anyone had the same or having the same problem and did anyone removed this god dammed irritating sound !
I can't adjust screen brightness using either function key or in control panel. Using the function key the little panel of brightness volume shows up on the screen but does nothing. And in control panel, through either the bottom brightness scroll or the power option won't change anything. Only time when the brightness will change is I unplug the power, but in the power settings it won't let me change/adjust the brightness.
And what is the battery function key for? I press it and it does nothing. XPS L521x
I have installed Windows 8.1 and install most of the drivers fro HP reccomended link. Even after that I am not able to adjust my brightness and WIFI .
View 5 Replies View RelatedI used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again.
