Q: Cannot adjust brightness windows 10 Lenovo IdeaPC

Thank you forum! Much gratitude here for your selfless service!!

I am not very tech savvy but I am usually able to solve my own problems. My cat jumped on my keyboard, my display went dim and I could not adjust it ! I am able to move the brightness bar up and down but nothing happens. First, I tried a system restore but that did not work. I went back about a month which was the earliest restore point I had. Then I went to device driver and looked to see if my driver was functioning properly. I was told it was updated and functioning properly. I tried clicking on the windows generic monitor driver also as advised which did nothing. I went to the device driver on the pc and updated from that which also did not work. I am using windows 10.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Two of the keys on the keyboard are used to adjust the brightness; but, if they are printed in the second color, you may need to hold down the Fn key for them to function. If you can't find them (they look like little suns), I need the model number of the Lenovo to help you more.

Well the title says it all... I updated Windows and brightness is now locked on minimum. Even if I press F12 or go into the settings, the brightness bar will fill but the screen won't show any changes at all. Sorry if I mispelled anything but I can barely see on this screen due to this issue. Can someone please enlighten me?

Hi, I can't adjust the screen brightness on my X250 at all. I have Windows 7 on it. When I press + and - the slider thing shows up, and it goes up and down, but nothing happens. It's really bright and have already been like this for weeks. The colour is slightly wrong as well. Restarting, shutting down or closing and opening the lid does nothing.It got stuck after I disconnected it from my docking station, so I tried connecting it and disconnecting again - nothing. I've updated Windows and nothing there as well. I'm getting really frustrated since nothing works.. Is there something to do? Please help..

Hello there, I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).I searched online and I tried:- updating/reinstalling/rolling back display drivers- resetting pc (reinstalling windows)- many other little repairs College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me

Using the laptop on battery, when I press on F11-12, the brightness meter is shown on the upper left like usual, but it won't move up or down.  Yet I think it's strange that all other places I can adjust brightness are fine, and especially strange that everything is working totally fine on AC power.
I tried uninstalling the Generic PnP monitor and reinstalling, but to no results.  Also, both my power settings on battery and on power indicate no adaptive brightness.

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

Beginning today, I opened my laptop from sleep and noticed the display was at its lowest brightness setting. I then tried to restart it to see if that would solve it, no luck. I did some googling and found out it could be a problem with the graphics driver. I then disabled it and enabled it. Now the brightness is at its max settings.

The function (FN) + F4, F5 (the keys to adjust the brightness settings) do nothing. The brightness status will show up on the screen and only change 1 or 2 notches.

I then realized I should have a way to adjust the brightness via the Power Settings in the Control Panel. I even confirmed this with a friend. I should have the sliders to adjust the brightness but I do not. It's very strange.

This is the screenshot from my friend:

Hi Sam,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to hear that brightness functionality is not working as expected in your Z400 Laptop; I suggest you to install LEM (Lenovo Energy Management) and the latest display drivers in the computer according to the relevant OS (Operating System) installed. Below are the links to download the relevant display driver:
 

Intel Video Driver for Windows 8.1(32-bit  or  64-bit)
Nvidia Video Driver for Windows 8.1(32-bit  or  64-bit)
Lenovo Power Management for Windows 8.1(32-bit, 64-bit)

Hope this helps!!!

Hey guys, so I've been having some problems since I updated to Windows 8.1. My screen is stuck on dim. It's not dim enough to be unusable, but it's dim enough that I wish I could turn the brightness up. If I use the hardkeys on my keyboard to turn it up or down, the bar will go up and down, but the brightness won't change. Same goes for using the settings charm brightness bar and adjusting via control panel. I've tried updating my display and video drivers, and messing around with the battery "power plan" settings, but after all that it still won't change. Any suggestions?

I am having this problem from past 3-4 days I am unable to adjust my laptop's brightness. The functions keys for brightness won't work. I also tried changing the power settings to high performance and balanced, that also doesn't changes the brightness.
I also tried manually adjusting the screen brightness. The slider moves but the brightness is not changing.

I am using IntelR (HD) Graphics family.
I tried changing it back to Microsoft basic display adapter but that also didn't help.

I got windows 8.1 installed from the factory itself and everything was working fine until past few days.

Any suggestions??

P.S. => I am using a Lenovo G50 series laptop

A:Unable to adjust brightness in my windows 8.1

First off, figure out whether or not your laptop has an ALS (Ambient Light Sensor) which will automatically adjust the brightness (if all goes well). Usually it won't override a manual setting, but it's kind of up to the developer which one takes precedence. As for the keys not working, you probably removed (or didn't install after a Windows reinstall) the helper software that controls these functions.

Hi there. I've installed a clean version of Windows 10 Home 64 bit, and, noticed that, with the basic Microsoft display adapter driver, I would be able to adjust screen brightness and would get maximum resolution as well. How ever, even though I disabled automatic driver updating in Windows before I first connected my laptop to the internet, it still proceeded to download a driver that it got via Windows update which ruins the adjusting of brightness. I tried to install the 64-bit Windows 8 driver that is available at support.lenovo.com but that one has the same problem, I can't adjust screen brightness when using it. Neither did the latest Windows 10 Radeon HD 6xxxM driver by AMD off of their website help at all. Everything else works perfectly fine in terms of Windows 10 except for adjusting of brightness, and, I am unable to stop Windows from constantly updating the graphics card driver via Windows Update despite the setting found in System Properties. As such, the laptop is, largely useless, and, has wasted loads of my time. It's a shame really, as, I invested loads into this laptop, and, though it's perfectly capable of running Windows 10, the fact that I can't adjust screen brightness wrecks everything. I have even installed the Energy Management driver, but, that doesn't help anything either. Could someone, please, advise me of some way through which I could make Windows simply STAY at the Basic Microsoft Display Adapter driver, or, w...

Hello,

I've installed Windows 7 on my Qosmio G30-140 but I'm having trouble adjusting the brightness settings.
Instead of allowing me to set the slider to any position I want I'm stuck with only 3 steps from which to choose from.
The last one is way to bright and my eyes keep tearing up from having to deal with this insane amount of white, especially on white backgrounds.
The other two are very, very dark.
What's going on? I've installed the correct Nvidia drivers.
Also I can't seem to set the brightness by using the FN keys on my keyboard. They simply produce no result at all.

Help appreciated, I can't work like this.

Hi

I have had an Asus laptop with windows 8.1 for almost two years. Two days ago, I found that I can no longer adjust the brightness. When I use F5/F6 the brightness bar goes up and down between two levels but the screen brightness isn't changing. This has happened before but fixed itself within a day. This doesn't seem to be happening this time. I have checked some solutions to this problem but most people seem to have this problem after an update or upgrade to windows 8.1. This is the same operating system I have been using for two years and, as far as I can tell, there has been no update in the last week. I've checked the drivers and there doesn't seem to have been a recent update.

Hello all, Im not the best when it comes to knowledge of computers and what not but I'm completely stumped and so is everyone else on the web, it seems. Cant find a solution to this for nothing. I also did a search here on screen brightness problems and didnt find anything specific to my problem..

Basically I just installed Windows home 7 ultimate on my HP dv5t after previously having vista on it and I cant find how to adjust the screen brightness. I've googled it and others have had the same problems but I cant find how to fix it. My fn shortcut doesnt work, and when I go to power options and all that, theres no slider or even option to adjust brightness. Ive seen where it's supposed to be on windows 7 via youtube videos but it's not there. Anyone know what to do, or has anyone heard of this??

The only thing I've found is a thread here, post 14, where they claim a guy found a solution but It doesnt work for me, or maybe Im doing it wrong but ive done it several times.

Any help would be appreciated! I cant stand it anymore, I feel like im about to go blind..

I've got the newest version of Windows Media Player 9 series on my XP Home edition. The video is very dark, even though my monitor Brightness is set to 100%. I know that when I have media actually playing, I can go to: View/Enhancements/Video Settings/ and set the Brightness to a higher setting, and this works fine. The only problem, is that when that media stops playing, the Brightness setting resets to the default, which is too dark. Besides being a hassle to set the Brightness where I want it every single time I use the Media Player, if I go to a web site that has a built-in Windows Media Player, there is no way for me to adjust that video, which is also always too dark. So I need to know how to adjust the Brightness setting on Windows Media Player so that it won't automatically reset to the default. Any ideas?

I've noticed, today, that I'm suddenly unable to adjust my screen brightness. I have read half a dozen threads reporting the same problem; I tried all the solutions therein (from updating the driver and reverting to the most basic one to manually changing power configurations) and nothing worked. Unlike the vast majority of users who had this problem, this hasn't happened following an update to windows 8.1 (which I did several months ago -- and the adjust was working fine after that).

This might give you a hint:

* As I try to adjust it using the fn key (as I had always done previously), brightness goes up or down just one level -- and that just 'cosmetically', as in fact nothing changes. The indicator gets stuck approximately in the middle of the bar, unable to reach the extremes.

* There is more: on power management, I chose the lowest possible level of brightness when working on battery, just to see what would happen. I then disconnected my laptop from main power, and... the brightness indicator did go down to the lowest level, YET brightness remained unaltered in fact.

Anyone, please??

is there any driver that i have to install or any way to fix this ?

A:Windows 7 Enterprise x64bit [ Cant adjust screen brightness ]

What driver pack? Win7 is a driver-complete OS after you enable Automatically deliver drivers via Windows Update (Step 3) then run all rounds of Impotant and Optional Windows Updates until no more are offered when doing a Check for Updates after reboot.

Any drivers then missing should be imported from the HP Support Downloads webpage for your exact model.

If you have an HP then don't reimport any of the HP bloatware but sometimes a piece of software is required to make the hotkeys function correctly. You'll need to study the software posted for your model to see which is required. If you tell us the exact model and link us to the webpage we can often spot it for you if you need help.

Hopefully you followed the other steps for a perfect Clean Reinstall - Factory OEM Windows 7 because you will get and keep a perfect install to the exact extent you stick with the tools and methods given.

If you forced a bunch of old drivers into an OS which provides its own drivers then you will have problems.

Ok I've had vista for a long time, but I switched over to XP and everything is perfect except from one small detail that is kinda big for me. I can't adjust the brightness in my laptopIn vista all I did was press fn left/right arrows to adjust it. And from what I know this is the way you do it in most laptopsNow in this XP I had to install all drivers. Specifically from this page http://www.laptop-software.com/acer-softwa...5738zg-drivers/when I install the graphics driver, VGA intel driver for vista is the one that's used for my computer from that list, the brightness just goes to the max apparently and I can't use fn arrows to adjust it. I CAN use fn arrows up and down to adjust the volume so there is definitely something fishy here. If I uninstall the driver I can use fn to adjust the brightness normally so I know the problem is when I install the driverthis brightness is driving me crazy! the driver bring something called Intel Graphic Media Accelerator which has an option for brightness, but it seems as if that's a different type of brightness cause it just makes the screen duller. You can actually still see a lot of brightness coming out from the computer but the screen is very dull. And it still damages my eyesany help?

Hi, Try the following. Download the graphics installer on the following link and save it to your Downloads folder. http://ftp.hp.com/pub/softpaq/sp72001-72500/sp72370.exe When complete, download and reinstall the Chipset driver on the following link. http://ftp.hp.com/pub/softpaq/sp69501-70000/sp69575.exe When the Chipset installation has completed, do not restart as prompted - instead, open your Downloads folder, right click on the graphics installer and select 'Run as Administrator' to start the installation. When this has completed, shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter. Start the notebook and let Windows fully load for a few minutes before checking if the f2/f3 buttons function. Regards, DP-K

my dell inspiron 5558 is log off while pressing f11 or f12 for brightness adjustments
 please solve my issue

A:cant adjust brightness

What operating system? That can make a difference. The top row F keys toggle between functions depending on using or not using the FN key-see your manual since diff computers have diff instructions. Try using the FN key with the F11, F12.

A:Re: Cant adjust brightness

Hi: The only suggestion I can offer would be for you to install the graphics driver and restart the PC. This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If highdefinition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp78001-78500/sp78245.exe
