Updated to windows 8.1 now can't adjust screen brightness

Basically I have been avoiding this update for a while now because I was quite happy with my hp laptop without it, but then a couple days ago my laptop decided to do the update automatically. So everything was fine until it rebooted and I realised my sound control buttons and brightness buttons had stopped working completely. I sorted the sound control easily on one of these forums but I have been having so much trouble trying to fix the brightness controls. This is really annoying me as the brightness is turned up fully and it is really hurting my eyes.
I have tried updating both the 'AMD Radeon HD 7600M Series' and the 'Microsoft Basic Display Adapter' on the device manager which has not worked at all.
Please can someone help!

Hi @gsh987 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Notebook and the brightness control on Windows 8.1 not working correctly after an update. I would uninstall all the display adapters that are in the device manager and restart the Notebook. Check to see if if it put an adapter back in , right click on the driver and update.
If that does not help I would uninstall the Graphics drivers restart the Notebook and it should reinstall the correct driver for you.
Here is a link to the HP Support Assistant. Just download and run the application and it will help with the software and drivers on your system that need updating.
I would be happy to assist if needed. How Do I Find My Model Number or Product Number?
Please let me know.
Thanks.

Re: Satellite L855 and Windows 8 - can not adjust screen brightness

Hi everyone !
I installed Windows 8 on my Satellite L855 and it is running pretty well except that I can no more adjust screen brightness !!! I updated all the drivers for Win 8 but it didn't resolve the issue.
Hope someone can help me !! Thanks !!

Hi
Did you install the VAP (value added package) provided with Toshiba Win 8 upgrade assistant?
Its necessary and the brightness can be controlled pressing F button
F2 Decreases screen brightness
F3 Increases screen brightness

Can't adjust screen brightness on Acer Aspire One anymore

It used to work before, but now that kernel26-one-dev is really outdated, I've started using the standard Arch kernel26 package. I can't adjust brightness with the fn keys, and GNOME's brightness adjustment applet says it's unable to get laptop brightness read.
I guess it could be acpid related, /sys/class/backlight/ is empty, but I'm currently doing a full system upgrade and will update the thread if that solves it.

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?

Can't adjust screen brightness.

On my Tecra R840-S830, I recently reinstalled Windows 7 64 bit and I thought I installed the drivers I needed. My flashcard functions are working perfectly except that FN-F6 and FN-F7 will not adjust the screen brightness. I can also find no other way to adjust the brightness-It doesn't appear in power options or display settings. Any ideas? Am I missing a specific driver?

Tecra R840-S830
Maybe this one?

Instead of struggling to get the install order correct, you should restore the hard disk to its original out-of-the-box contents using Toshiba recovery media.

HP ProBook 4510s: Can't adjust screen brightness

It seems to be a recurrent problem and I try everything I can to solve this by myself but I do not have any solution left so here it goes.
I have installed archlinux and gnome 3, everything is up to date but I can't set the screen brightness (I am using the xf86-video-ati drivers with a Radeon mobility HD4300). I can't set it via the gnome control center, via xbacklight or setpci. When I try the fn keys, I get this message:
"No backlights were found on your system",
By googling, I tried to add the acpi_backlight=vendor and acpi_osi=Linux or acpi_osi="" to the kernel line but still the same message. I installed the linux-kamal kernel but still not working. I have no entry in /sys/class/backlight and no video folder in /proc/acpi so I can't set the brightness with echo <some value>.
Maybe someone could help me since I don't know what to do now and the brightness is locked to 100%, really hurting my eyes.

Try to disable acpi boot kernel with option “acpi=off” .
When it works, there must be bug in BIOS or ACPI on at model,

Updated to windows 8.1 now can't install Photoshop Elements 12, HELP PLEASE

I am having such a terrible time getting Photoshop Elements 12 to install on my computer. I've had Dell software support and Adobe support's help but they could only get to the point of JUST the editor being installed. The organizer and the ability to go online never gets installed. After all the files are downloaded and the installation begins a box comes up and wants to uninstall the program. I couldn't get past this part but the software tech got past it. I have spent hours and days trying to get this installed. I've been a big fan of Adobe products but this is the first time I haven't gotten the HELP I need. It has to be a software issue because i've downloaded other programs with no problems. I even went out and brought an external cd/dvd burner and tried installing from the hard cd only to have the same problem pop up. If it helps, I got the Windows 8.1 update maybe this is the problem. PLEASE PLEASE PLEASE CAN SOMEONE HELP ME!!!

Can't adjust screen brightness on Windows 7

Running on my late 2011' MacBook Pro 15" with Windows 7 Home Premium 64-bit Service Pack 1. I have an AMD Radeon HD 6750M graphics card. I have tried uninstalling the driver and what not. I can't seem to find a catalyst that will work. It always tells me that I don't have a proper graphics adapter.
This is my 3rd time posting this, I'm hoping someone will have an answer.

Well, I should elaborate more on the methods I have tried. (Also I am using a MacBook Pro, however that doesn't matter really) I have tried uninstalling my graphics card driver in 'Device Manager', I have tried using catalyst to install the driver (I'm using an AMD Radeon HD 6750M), I have downloaded 'Windows Support' through Bootcamp and have reinstalled Bootcamp on Windows 7 and tried using the drivers provided but nothing has worked. I have even tried this, Control Panel > User Accounts > Change User Account Control settings > slide control to 'Never notify' > Reboot, with no luck.
Also, thank you for the response.

I can't adjust screen brightness

It happens the first time, when I hit F1 and F2 to adjust the brightness, the icon shows only one notch at the dimmest, the screen is at the brightest setting, hit F2 nothing happened, it stayed the same, reboot and it works again. Any idea? Thanks

It's happened to me the once. For me a restart resolved it and suspect putting my MBP back to sleep and waking again would too but anyway.
What appears to be happening is that when your MBP wakes it is failing to recognise the state of your display brightness when it is put to sleep so in a state on confusion it just sets itself at max brightness. The problem arises when software think the display is not at max brightness and get errors when it tries to raise brightness.
I've since reported this to Apple so hopefully something will come of it.

uninstall pse 10 (properly using the adobe uninstaller).
clean - Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
then try reinstalling using the adobe installation file(s).
if you see an activation count error while trying to reinstall contact adobe support, https://helpx.adobe.com/contact.html
and ask for an activation count reset.

I updated cs6 camera raw and now can't see the camera metadata I used to see and cannot find it in photoshop itself.

I have just agreed to software updates on my imac and now can't open my mail. There is a message saying this version of mail isn't compatible with this latest software. I have located the updated mail in the applications folder but it won't open. I don't have the original operating software disk. Does anyone have any suggestions?

Your reply suggests that you have moved Mail to a different location, which (as I said) will prevent it from being properly updated. You cannot use Mail 4.5 with any recent version of Mac OS X. Mac OS X 10.7 (Lion) included Mail 5 and Mac OS X 10.8 (Mountain Lion) includes Mail 6. I'm assuming that you have either Lion or Mountain Lion, but if that is incorrect, you will need to provide that information.
At this point, you will need to reinstall your system. Hold down command-R at startup and reinstall the system right on top of the old one. This should not disturb any of your documents or applications, though you should have backups beforehand in case something goes wrong. And at this point, with your system in an uncertain state (I don't entirely know what you have done to it), something could go wrong.
You will also want to delete the old copy of Mail 4.5, wherever that is. You can't use it.
In the future, do not move any of the preinstalled applications. Leave them where they are.

Windows can not adjust the brightness on this display

I have a Toshiba Satellite LX835-D3300 ( Serial #ZC119804Q )
I want to brighten my display, but it tells me..... Windows can not adjust the brightness on this display.
In my HELP section on my computer it tells me to...
Tap or click PC and devices, then tap or click Display
Make sure the Adjust my screen brightness automatically slider is turned on
Get the best display on your monitor - Microsoft Windows Help
(If you don't want the screen brightness to change automatically, tap or click the Adjust my screen brightness automatically slider to turn it off.)
Tap or click Apply.
I do not have that.
I notice that if I go to the side of my screen and then click on Devices, click on projects... "Second Screen" is showning
I clicked on it and then I went and clicked on PC screen only and it is highlighted, but when I go back to it, it stills shows "Second Sreen"
Please help me. What am I doing wrong
