Feature Change: Remove useless adjust screen brightness button.

Remove useless button for screen brightness.
both buttons serve same function.

Oh - that explains it better.
You do know that not every computer using Windows 10 has a key available to adjust screen brightness though, right? Or, as in the case of the Surface, if you don't have a keyboard, the only way to adjust the brightness is only the software one?
For you it might not make sense, but include ~1 billion more people, and I think they should just leave both.

Have Upgrade Graphic Card Driver, But Still Cannot Adjust Screen Brightness and Sleep Button Not Showing After Clean Installation of Windows 8.1

I have done clean installation of Windows 8.1 on my HP Pavilion G4.
Then I realize that I cannot put my computer on sleep mode and cannot adjust screen brightness.
I understand that those problems caused by the graphic card driver.
My computer is running on AMD Radeon HD 6400 series.
Thus, I manually search on internet and found a latest graphic card update on microsoft site that is claimed compatible on windows 8.1 (link: http://msdn.microsoft.com/en-us/library/windows/apps/dn344644.aspx).
I've upgraded it into the latest one. I've check on Device Manager, the driver is running well.
But my problem did not solved!
Please give me the solution!

Hi,
How about go to Device Manager, then uninstall Graphic driver and restart your computer, system will install its build in graphic drver. You can have a try.
In addition, access to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Brightness and set its value to 100 for test.

Cannot Adjust Screen Brightness with Fn Keys on New L540 (8.1 x64)

Hello everyone. I just purchased a new L540 with Windows 8.1 x64 on it and have run into a problem I'm seeing is apparently common. While my other Fn keys work as intended, I cannot adjust screen brightness with them. Pressing the buttons just does nothing and the laptop is running at full brightness at all times, even when on the battery. I have installed the latest Power Management Driver and from what I can tell, there is no version of the Power Management Software for anything newer than Windows 7. I also have installed the latest Hotkey driver (in fact, I've installed all the latest drivers for this machine.) I read in another thread that this can be caused by the latest HD Graphics driver from Intel but I actually can't even install that driver (says my system is not supported) so I am still using the latest Lenovo provided driver.
Can anyone please assist with this? I want to be able to quickly adjust screen brightness when on battery but I can't do that at present. Thanks!
Solved!
Go to Solution.

I have the same problem with my L540. It started with the update of the BIOS to version 1.65. Because I didn't find a solution, I went back to BIOS version 1.64, where all the brightness options are there and work properly.
You can download older versions. When on the page with the new drivers (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS037285) go to BIOS Driver 1.65, then choose "learn more". At the end of the following page you'll see all the older versions.
That you can install version 1.64, you have to change the "Secure RollBack Prevention" Option in the BIOS: Restart the Computer. When you see the option "To interrupt normal startup, press Enter", press Enter. Press once again Enter. Press F1 to enter the BIOS Setup Utility. Choose "Security" -> then "UEFI Bios Update Option" -> then "Secure RollBack Prevention". Change this option to "Disabled". Then press F10 to save configuration changes and exit.
After restarting Windows you can install BIOS 1.64.
Another possibility is to wait for the next BIOS version ....

How adjust screen brightness in Windows 7?

I used to use a Windows 98 laptop up to 3+ years ago, but since moving to Mac have largely forgotten how Windows works. I now have Windows 7 on Bootcamp and can't see how to adjust screen brightness. Surely there should be an adjuster on the System Tray (that's what it used to be called) bottom right next to the clock. I'm on 20" iMac with Apple keyboard (the long one with number pad at the right).

Does the keyboard have brightness controls on the F keys?
If these do not work: try holding fn and using the F keys.
If that does now work I have to ask: have you installed the bootcamp software? you need to make a CD (or usb stick) of drivers and software from OSX then boot into wiondows and run it.

Cannot adjust screen brightness

I have a Lenovo G585 and after updating to Windows 8.1 can no longer adjust the screen brightness, it used to work fine. I also had a problem with sound after I installed 8.1 but managed to fix that.
Adjusting the brightness from Settings > Brightness does not work, nor does adjusting brightness from Battery Life > Adjust Screen Brightness or by using fn + up/down key.

hi jackbeazley,
Welcome to Lenovo Community Forums!
Open Device Manager and open Display adater.
Right click on AMD graphics and choose Uninstall
Be sure to place a check under delete driver software for this device.
Now Restart the computer and install this driver
AMD Video Driver
Check if the Screen Brightness will work now
Hope this helps
Cheers!

I have tried uninstalling the Graphic drivers, re installing from hp assistant, I even tried directly from Intel drivers but it is not letting me adjust brightness =( Latest driver version to my 4400 Gcard was 27/07/2015 I guess we have to wait since those drivers are win8.1 compatible only =(
Hey, I tried updating the driver, I googled something like intel graphic 4400 windows 10
Then I found this link
https://downloadcenter.intel.com/download/25150/Intel-Iris-Iris-Pro-and-HD-Graphics-Production-Driver-for-Windows-10-64-bit
read at descriptions to see compatible chipset. After I downloaded it started installing and the screen starting to do the "power off" think it does whenever you're installing video drivers et voila! ´the brightness went down and now my "brightness up and down" keys are working ='3
I hope this help you guys

Cannot Adjust Screen Brightness after Windows 8.1 Update

Cannot Adjust Screen Brightness after Windows 8.1 Update....i am using sony vaio laptop....i recently updated windows 8 to 8.1

Hi:
Most likely you need to install the graphics driver for W8.1 from your PC's support and driver page.

My macbook pro keyboard has stopped working overnight. The DEL button, along with O and P are acting strange. The DEL button is adjusting screen brightness and the O isnt working at all. Is this hardware related? or a software issue?

The left side of the keyboard seems to be working fine but the DEL button and other buttons are doing strange commands. The DEL button is adjusting the brightness and other F commands.
The O is not working at all. Some other letters are coming up with other characters.

Try a different keyboard with your computer if possible. If it woks well, it's a hardware problem.

Adjust Screen Brightness

I am currently using a HP ProBook 450 Gi - Serial # [Personal Information Removed] and i am unable to adjust the brightness of my screen.
I do have a secondary screen plugged in via screen cable connection.
Please help - its driving me crazy!

Dear Customer,
Welcome and Thank you for posting your query on HP Support Forum
It looks like you are trying to find the steps to increase or decrease the screen brightness for your Notebook
Method 01.
Open Windows Control Panel, click on Hardware and Sound, then in the Power Options Section, click on
"Change power-saving settings." There's a slider to adjust brightness at the bottom of the window.
Method 02.
Open Windows Control Panel, open Windows Mobility Centre and adjust the brightness here
Method 03.
On most of the Notebooks, tapping F3 and F2 Key will often increase and decrease the screen brightness
Please check the links shown below if the above mentioned method doesnt resolve your issue:

Adjust Screen Brightness Satellite Pro 4200

Hello,
i heard from a combination of keys which makes adjusting the screen brightness possible.
Is that true and what is the key-combination?
Yours sincerely
Riedlz

Hello
Nicky is absolutely right but as far as I know all Toshiba notebooks have the same keyboard and all have the same key combination for brightness changing. Your Satellite Pro is pretty old and at this time maybe it was a little different.
Like Nicky already said check the Users manuals or you can download one if you need it.
You can find it under http://209.167.114.38/support/Download/ln_byModel.htm

Can't Adjust Screen Brightness MBP 2010

Hi everybody, this issue is driving me nuts!
I've browsed all the sections on this forum and numerous threads and still no dice... Here's my issue:
-I own an late 2010 MacBook Pro (iOS dev machine), which was working perfectly up to the point where I had to update to Mountain Lion 10.8.5
After the update, brightness control on the keyboard is gone (F1 and F2 are duds), also no manual control anywhere else...what gives??
I've done all the SMC reset mumbo-jumbo without any avail....seriously, it sounds like the old fix for windows 98..."just reboot and it will be fine...or not". I also won't accept "go to a genious bar" as answer, since that doens't exist on these parts and any "procedure" over a apple device will take over a month to be done with.
So my questions are:
1-What where they thinking when they removed the frigging slider from settings?? Do they take us for some sort of idiots that can't be trusted to handle their brightness without using the keyboard?
2-Why can't I change the brightness on my $2500 laptop after a software update? Pray, do explain how this has come to be?
3-Is there any command (using terminal) that I can run to permanently set the brightness level or just to, you know...change it?
4-I'd like to scale this issue with a formal complaint towards apple, I find this to be unacceptable as a customer and I'd like to give them a piece of my mind. Can someone point me out on the proper path to do this?

Unable to adjust screen brightness

i can see the logo on screen when i press f2 and f3 but the brightness do not changes .. all the other functions work like radio switch , audio adjust etc..
i have hp 1000-1b10au

Hi:
If you reinstalled or installed a different operating system you need to install the correct graphics driver in order to adjust the screen brightness.
Without the graphics driver the brightness will be stuck on maximum, amongst other problems.

Feature Change: Remove useless adjust screen brightness button.
