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.
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.
This afternoon I decided to do a clean install of windows 8.1 on my Acer Aspire v5-431P. Everything went well and it booted up as it should do. After completing the windows setup procedure, I went on to reinstall all the drivers. Everything was still fine. When I was downloading them from the Acer website I heard the sound a windows computer makes when a device is plugged in or out. The screen went off and on and the image was blurry and flickering. Like it's covered in water. I also see everything double. But very vague.
I tried to reboot the laptop, took out the battery, plugged it in and out of the power source etc. The problem occurs after the windows login screen. The acer bios logo and the windows startup logo are perfectly fine but after that it's cr*p. At this point I was certain the screen itself was perfectly fine so I tried testing is on my tv using and HDMI cable. Worked perfectly.
The last thing I tried was reinstalling windows but the same happened. After 5 minutes of usage the screen goes ham again.
I m using HP Pavillion N208TX with windows 8.1 64 bit version. i m not able to adjust screen brightness from f2 and f3 button and from the power setting also. when i press these buttons it shows the slider to adjust the brightness on top left corner of the screen but its does not adjust the brightness from low to high. i have already updated the Intel HD Graphic driver...
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).
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

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 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 got my new Acer Aspire V14 touch (Windows 8.1) and want to connect it to my Sharp Aquos LC-32DA5U TV via HDMI. I can see the picture but cannot adjust the screen resolution to the native resolution recommended for this TV (1366x768). Funny enough this is exactly the resolution my laptop is using.
When I force use of this resolution via show all in the display properties, then I don't get a picture but just a black screen on my TV.
Is there any other driver etc that I need to install to make this work? It worked perfectly fine as PnP with my old Lenovo computer under Windows 7.
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 got an acer aspire e15 for xmas and I've started to have problems with it like when i turn it on and adjust the screen or simply pick it up to move it the screen will turn off like a standby but take ages coming back on and sometimes it will just simple restart the laptop....
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 own a 3.5 years old Acer Aspire 5742G (Core i3 M380; NVIDIA540M). the heat sink or the collinig fan might have some issue as it usually gets overheated when playing games (even CS condition zero/1.6). I don't play games anymore, so its not a problem.
The problem is that I am unable to adjust the screen brightness from the keyboars shortcut (Fn+ Left/Right arrow key), neither from the control panel (Power Settings).
Although I do noticed something that, if I change my brightness settings (nothing happens) and I close the laptop lid (display screen) by folding it down and openeing it back after 3-4 seconds, the brightness is now changed.
Screen automatically dims as I go in little dark areas and gets too bright when it has so much light around it. I am trying Fn+ arrow keys but they make very less difference. Is there any way to control this?
I am using Windows 8.1 and display drivers are Intel HD Graphics Family version 10.18.10.3316.
I own an Acer Aspire 5742, model no. PEW71. It is running on Windows 7. I included a vid for you to see what the problem is: [URL] ....
So, as you can see, the computer can be turned on, but it doesn't get through the acer screen on to the windows picture, and it automatically reboots and shuts itself down again over and over again. This has happened in the past, but the repairers have reset the operating system and BIOS. They also switched the hard disk for a new one, but this could be because of some other problems I was having (USB channels weren't working).
Everything worked fine for a month or so, and then it happened again. I myself am thinking about the motherboard being damaged.When this happened in the past however, I was still able to turn on my PC sometimes, so I was also able to save my files. Now on the other hand, I can't get the computer on anymore. The most important thing to me is saving the files. After that, I'll take it away for reparation again, where they will probably delete everything again (I can't commicate with the repairers myself, so I can't discuss terms or anything).
At the end of the vid you can see me turning off the computer by pulling out the adapter. Removing both the adapter and accu is the only way the computer can be turned off. Even shutting it down by pushing the on/off button for 5 seconds will not prevent the auto re-boot.
I've run the Win 7 upgrade adviser and it says the system can run Win 7 as it has CPU 1.6 Ghz and 2.0 GB of RAM. However in the device section it says that the Mobile Intel (R) 915GM/GMS, 910GML Express Chipset Family is not compatible - driver not compatible with Windows 7 . Is there a driver I can download to fix this problem? I've checked the Intel download web site but can't determine whether a driver exists or not ??
