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.
View 3 RepliesI 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.
Â
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.
My Aspire E15's brightness is locked at maximum capacity. I can't change it in power options or with the Fn key. It is the same whether connected to the AC adapter or not. While using the Fn key and pressing Fn+Left Key or Fn+Right Key, the on-screen brightness indicator alternates between two levels but the brightness of the screen doesn't change.
View 3 Replies View RelatedI've recently bought an HP Probook430 and installed Windows 7 Ultimate 32bit and I don't seem to be able to change the display brightness, using the fn button+f9/f10 (although volume settings are changed in the same method smoothly).
Although the brightness settings don't seem to change, this bar does appear when pressing fn+f9/f10. What should I do in order to make the display brightness settings changable?
I bought a dv3t-2000 two months ago and recently i installed windows 7 and i just realize that is not possible to change the brightness on the screen, is always the same. I have tried changing the power plans, I've upgraded the BIOS, but so far is not working.

View 1 Replies View RelatedI 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.
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 .

I got my Dell 1557 about a month ago and for a while, it seemed just fine with my display brightness.
I could change it to however bright I want it to be. Then today, when I turned on my computer, my settings for my display brightness was at the highest when it normally is in the middle.
At first I thought nothing of it because I could easily change it with the F4 and F5 buttons, but after I logged on and tried to change it, nothing happened. Not even after I restarted the computer or reinstall the ATI Catalyst Center.

Windows 7 Home Premium 64 bit
Core i7-720QM

Full HD 1080p High Brightness LED
I've done a search and couldn't find anything relevant.
My FZ of 28 months old has suddenly started making a faint buzzing noise from the screen.
At first I thought it was the fan, but I realized it's the LCD. I can't change the brightness for some reason using Windows 7 but it's on Max Bright. I've seen some threads of people having this problem on lowered brightness levels but this is happening on full.
When I shut the lid, the buzzing stops. It can be heard if I stand behind the laptop or place my ear beside either rear corner of the laptop.
I did a clean install of Windows 7. I did not load all that crap from the 2nd CD.I am trying to determine which Drivers I need to install.
I installed the VAIO® Event Service and Sony® Shared Library.
What is strange is, when I click on the FN button and press the increase brightness key, the brightness meter does appear on the screen, but it will not go above the lowest setting.
Can I adjust the brightness to maximum value or any value when in stamina mode on the Z ?

Â
It appears the only way to adjust the brightness is to use Intel HD Graphics, which isn't so convenient.
Â
Fn keys don't work. changing the brightness on the Power Manager settings doesn't work. There is no brightness option on Windows Power Manager.
Â
I have Intel HD Graphics 4600 10.18.10.3960
I have Lenovo Power Manager 6.66.3

Edit: In fact, I think it's posisble that Power Manager to just outright no longer works.
For some reason I can't change my screen brightness anymore. I've already tried a HD 4000 driver rollback to version 9.17.10.3223 and I also disabled "adaptive screen brightness" at the power management. For some reason I can change the brightness by using the "microsoft basic display adapter" driver instead of the HD 4000 but that isn't a real solution.

Any driver i have to install ? if required then driver download link.
I am unable to disable the adaptive brightness on the i5 HD 5500 1080p version of the new XPS 13.
When I view a dark page, the screen will dim, and when I view a bright page, the screen will get brighter. This is extremely annoying and all the options I've tried have not fixed this issue at all.
Turning off the enable adaptive brightness option in the advanced power settings does nothing. I have this done on all power plans.
The option for disabling it that should be in the Intel Graphics Driver does not exist.
Disabling the Sensor Monitoring Service doesn't fix it either.
I have the latest version of the Intel Graphics drivers. Uninstalling it doesn't fix it either.
Installing another operating system doesn't fix it either, so I'm assuming this is some sort of hardware problem.
