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.

The display of my hp pavilion 15 N 043ee laptop is extremely dim. I'm unable to see anything on the screen unless I shine a flashlight onto it, and even then I can barely see. When I connect it to an external monitor it works fine. I restarted it and hit f8 to access the bios screen and it's also dim there as well. My laptop is only a few months old ....

The brightness on my HP 15-r018dx Notebook PC won't change, not using the function keys or the slider in "Power Options". This started happening two days ago; before then I had no issues. I am not sure what changed between then and now.

I just got a new HP Pavilion G4-1310au. My problem is that it did not have any OS installed and so no system drivers were installed either. In the box I only got a CD that has HP manual in it and nothing else and the notebook of course, the power cord, bag, and some printed manual. I was expecting to see a System Disk CD so I could install the system drivers, but I didn't find one.
So I installed the OS and then installed the network driver which I downloaded from another computer and also the audio. My problem is that I cannot find a launcher that would control the brightness and contrast of the screen. I tried FN key plus F3 or F2 keys but it didn't work.
How I can control the brightness and contrast or better yet if there is a Launcher software where I can control all the features of this notebook? By the way, I don't know how to enable the bluetooth either.

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 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 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.

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 updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.
