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 ....

View 3 Replies View RelatedI 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 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.
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.

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

I have lenovo ideapad z510 came with windows 8.Then I have installed ubuntu 13.10 on it. But when ever I turn on my laptop in ubuntu brightness set to 0 & I have to manullay adjust it.
How could i turnoff it s.t. it stays as it is.
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 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 2 Replies View RelatedI 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.
View 3 Replies View RelatedI 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....
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.
Brightness on thinkpad doesn't work.
I have reinstalled my thinkpad W540. For display driver I have downloaded latest version from Nvidia. All other drivers are installed from Lenovo website.
OS: Win8.1 pro
When I push the F5 or F6, display brightness bar is shown, but nothing happens.
Already tried
- reinstall drivers after delete device in device manager
- reinstall programs after delete all drivers from nvidia and intel in program and features
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.
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...
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.

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 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
