Sony :: Can't Adjust Brightness In Win7 X64 On Vaio CS
Aug 11, 2009
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'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
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 .....
For 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.
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.
I have a HP Envy dv7 Notebook PC. It recently just downloaded the new HP Assistant and I wanted to adjust the brightness because it was too bright for the dark room I was in. I tried using the F2 and F3 keys to lower the brightness and I tried to adjust it from settings and control panal but the brightness doesn't adjust when I move it up or down. I tried shutting down my computer and restarting it but I still can't adjust the brightness.
Brightness is stable and the keys of btightness up and down are not working or can say that not changes the screen brightness. since so long and due to this the battrey backup is affacted..Having windows 7 ultimate 32 bit..
I have a HP 1000-1405TU Notebook PC. My Notebook Product ID is D9H61PA#UUF. I am using Windows 7, 64 bit version. I tried using the F2 and F3 keys to lower the brightness and I tried to adjust it from settings and control panal but the brightness doesn't adjust when I move it up or down. (Note. When I use Windows 8 on this PC then there is no problem like that).
I can't adjust or change my brightness with the hotkey (F11 and F12) or even with the slider in settings. option brightness of my laptop doesn"t change it is stationary.
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 just seem to unable to adjust the brightness of my screen. I tried restarting my computer, adjusting using f2/f3 or through settings it doesn't work?
My computer is HP ENVY 15-j175nr and my product numer is F7Q25PA#AB4.
I have just received my upgrade for my VGN-Z21WN/B (my baby, love it!)... anyway, I did a bit of research before receiving it and everywhere I read suggested to do a fresh install - so thats' what I did. It actually all went okay, and it's happily running.
I visited vaio-link.com where I found some Win7 drivers, including:
- Bluetooth driver - Realtek HD audio - BIOS update for Win7 - Ethernet Driver - Fingerprint suite - Wireless LAN (Intel ProSet) - WWAN - nVidia graphics driver
All great , except now I am missing my FN keys. The FN keys for brightness, volume, switching display etc no longer work, and I cannot find a solution. One site I researched says to download the vista driver, but I cannot find that anywhere .. and then even people said that didn't work.
Secondly, although not a biggie, is there a VAIO Update driver?
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 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.
I have XPS 15 (L501x) laptop. I cant adjust the brightness of my screen through the function keys(quick set) or from Control panel (Control PanelAll Control Panel ItemsPower Options)I have already tried
Reinstalling quick set Restoring Reinstall Drivers from my Drivers CD Chipset : Intel HM57 Video drivers : Intel HD graphics
I also tried to install bios drives, but the system would allow me, saying, its already the latest
For some reason when i press on the FN+F4 or F5 this brings up the small display showing the brightness level but it will only move the level one or two notches in either direction. It will not adjust the brightness of the LCD display on the laptop at all.
I have a W540 with 3K Ips panel and Windows 7 Pro 64bit.
I recently installed a new hard drive and installed windows 7 pro 64 (previously on the other hard drive was Windows 8.1 Pro 64 bit ( there I could change the brightness ) )
My problem is that I can not change the brightness .
I've already tried:
-Reinstalled all NVIDIA driver -Reinstalled all Intel graphic drivers new -Reinstalled Intel and Nvidia drivers simultaneously -Remove Lenovo Power management -Tried to install NVIDIA driver from the Lenovo and the Nvidia page -Reinstalled Windows
Basically the Fn Button, Left, Right, Up, Down buttons are all working fine. I can adjust the volume of the notebook, but I can't however adjust the brightness of the screen. There is no brightness setting in my notebook whatsoever! Am I missing the brightness driver? what is the name of the brightness driver? Or is it something else. Taking into account that I have decrease/increase brightness symbols on the left/right buttons respectively.
