Dell XPS 15 L501x :: Can't Adjust Brightness Of Screen Through Function Keys
Feb 19, 2013
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
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
Suddenly I can't change my screen brightness with f2 and f3, and neither in control panel. Is there a new driver I need to install ? My product number is > G6S71UA#ABA
I have installed the latest driers and since then I am unable to change the screen brightness using function keys. I have installed multiple driver updates hence it is difficult to find out which driver is causing the issue.
I have an Aspire 5733Z laptop and I love it dearly. I just recently lost the capability to adjust the volume using the keyboard shortcut of Fn key with up or down arrow keys. I have uninstalled and installed the Realtek HD driver.
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 open this post to report a brightness problem on Lenovo Z500 Ideapad. Yesterday I've upgraded to OS Windows 8.1 and when I adjusted the screen brightness it goes off, and brightness adjust function doesn't works. I've solved my problem reinstalling the Intel video drivers, downloaded from Lenovo Driver Support.
It seems that Windows 8.1 upgrade disables video drivers.
I'm having the same trouble with my brand new 8460p : the brightness of the display can not be adjusted with the function keys (fn+F-keys) while in Windows. In other threads the problem has been solved by installing newest chipset drivers (which was not provided by HP), but in these threads the computer has been an earlier model. 8460p has the new QM67 express chipset and currently I'm running the latest drivers (according to intel's detection web site) for it.
I'm running a fresh install of Windows 7 Enterprise 64bit with all the latest drivers.
I cannot adjust the brightness of my display using the Fn keys or the Control Panel... I have already had to replace my battery once... I need to be able to adjust the brightness in order save my battery life!
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.
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 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.
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 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 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.

I own an Ideapad Z-500 notebook running Win 8.1.After updating Intel graphic adapter from Windows Update the screen brightness adjust key (F11 and F12) stops working and I cannot adjust my scrren brightness.I have to uninstall it and disable Windows update to keep using my laptop.

I am having an issue with my Acer Aspire V5-431P-4653 running Windows 8.1, namely, I cannot adjust the screen brightness at all. It seems to arbitrarily select a brightness level upon start up and from that point I cannot change it via the Fn and directional keys or through the control panel power settings. I have owned the laptop for a year and a half and this problem began roughly a week ago.
Of note, when I attempt to use the Fn and directional keys the brightness icon that pops up stays at the frozen brightness level - it does not move at all. In contrast, when I open the power settings and attempte to change the brightness from there, the brightness slider will move wherever I drag it, but the screen's brightness itself does not change. At startup the screen's brightness may be at full, minimum or somewhere in between - but regardless it will not adjust.
I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.
I recently downgraded my G710 from Windows 8 (which it came with), to Windows 7. The only issue I've noticed is that it does not display anything on screen when you use the function keys, such as the volume up or down, or bright ness up or down. The keys work, but it would be nice to see on screen that my volume is set at 2% vs say 100% when I'm turning it up or down.
I recently received a new laptop at work (a few of us have) and we are all having the same issue with this laptop. The function keys F8 and F9, which are labeled to control screen brightness, are not working. I have searched many forums and I cannot find a fix.

The screens are so dim it's hard to see the content on them.
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?
