Dell XPS 15 :: Can't Adjust Screen Brightness Using Either Function Key Or In Control Panel

Dec 4, 2013

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

It seems that Windows 8.1 upgrade disables video drivers.

Apple :: Friggin Electric Sound When Adjust Your Screen's Brightness

Mar 30, 2009

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 !

Lenovo P400 P/Y/Z Series :: Touch Screen Brightness Won't Adjust

Apr 13, 2013

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.

Acer Aspire V5-431P-4653 :: Cannot Adjust Screen Brightness Running Windows 8.1

Feb 27, 2015

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.

HP Pavilion Dv6-6173cl Display :: Unable To Control Screen Brightness?

Dec 31, 2011

I have a Pavilion dv6-6173cl laptop. It's been working fine until recently, when I left it on overnight to finish downloading a huge file. When I tried to adjust the brightness the next morning, I couldn't (though it was still at full brightness like I always keep it). So I thought, "why not reboot it?" I rebooted and now the display is the dimmest it can get with no way of adjusting the brightness using the brightness keys, control panel, or otherwise.
 
This has happened before. When it did, I did a factory reset on it and it fixed the problem. However, although there is no absolutely critical data on there and I can always make a backup, I prefer to not have to go through all that if it's avoidable. I have an external display that HP asked me to connect it to to see if it was a hardware or software issue. The external display was at full brightness, so when they asked me to ship it in I did a factory reset and that solved the problem. And now it's back.

Dell :: Inspiron 9300 No Brightness Control/white Screen At Bootup After Graphics Card Change

Jan 8, 2010

I have Inspiron 9300. Unfortunately, my geforce 6800 died and I bought as a replacement x300 which was installed by a laptop repair service (they fixed other thins too.

It was due to power surge). Everything works but when I boot up the computer or when the display is set to be turned off in the power settings in Windows instead of being actually turned off the display is on and is all white.

Also brightness regulation does not work via Fn +arrows keys and is set to maximum and the white color is so intense that I get a headache after a couple of hours staring at the screen.

Dell :: Studio 1745Can't Adjust Brightness

Nov 24, 2009

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?
