Cannot adjust screen brightness after BIOS update

I was able to adjust my laptop screen brightness but after the BIOS update:
https://bbs.archlinux.org/viewtopic.php?id=132077
I'm not any-more able to adjust it by hitting F2 / F3
Any good suggestion on what to use to manage volume, /brightness etc? or why now isn't working anymore?
Thanks.

HI,
thanks for the heads up, however I think the problem could be related also to my keyboard layout.
Current
cat /etc/X11/xorg.conf.d/10-synaptics.conf | grep -i model
Option "XkbModel" "hpdv5"
Actually my HP is dv6 and I see now that the keyboard is totally different:
DV5 http://images.google.com/imgres?q=hp+dv … 29,r:0,s:0
DV6 http://images.google.com/imgres?q=hp+dv … 29,r:1,s:0
What Xkbmodel should I use?
Currently available:
$ cat /usr/share/X11/xkb/rules/base.lst | grep -i hp
hpi6 Hewlett-Packard Internet Keyboard
hp250x Hewlett-Packard SK-250x Multimedia Keyboard
hpxe3gc Hewlett-Packard Omnibook XE3 GC
hpxe3gf Hewlett-Packard Omnibook XE3 GF

Hey, I tried updating the driver, I googled something like intel graphic 4400 windows 10
Then I found this link

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.

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 ....

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!

Completely unsolvable: Cannot change screen brightness after I upgraded my ThinkPad's display.

I have a ThinkPad X240 which came with a 1366x768 TN panel, I hated it and so after a while I upgraded it to an IPS 1080p display. It works great and looks fantastic except it's stuck on max brightness inside of Windows 8.1. I cannot change the brightness inside of Intel HD graphics settings or inside of programs like Display Tuner. It doesn't work in Windows 10 either. The weird thing is, I can change the brightness just fine inside of Ubuntu. I've tried uninstalling the Intel HD drivers and reinstalling them, I've tried switching the drivers to the Microsoft Basic Display Adapter, and none has worked. I feel like I've installed every single version of Intel's Graphics Drivers and that I've done everything and it still won't change the bloody brightness. NOTHING has worked except to just use Ubuntu, which is not an adequate solution. I've even gone as far as to update my BIOS and reset it to defaults, I've even pulled the CMOS battery. I've tried the version of the Intel HD driver from Lenovo for the X240 and I've installed the monitor.ini files. I've also just learned that during the Windows Boot Logo, the FN keys WILL change the brightness, but as soon as Windows is done booting, it stops working. This, coupled with the fact that brightness control works in Ubuntu means that this must be something related to Windows right? Brightness control works in BIOS. I've even gone so far as to try and change the brightness through CMD using powercfg according to this post. http://superuser.com/questions/472081/can-i-force-a-greater-screen-brightness-from-windows-command-prompt I'm really starting to lose patience now as it has been like this for 3 weeks and I can't be using Ubuntu all of the time, I honestly do not know what to do, it seems like this problem is completely unsolvable. Edit: I even got so frustrated that I switched off the laptop, installed the old screen, booted up Windows, and the brightness worked. Then (I know this is a bad idea) WHILE IT WAS ON, I pulled the old display and put connected the new one. And lo and behold, the brightness **bleep**ING worked in windows on the new display.

try change drivers

Cant adjust screen brightness after reinstalling windows_DV7-4080us

Need help with my HP DV7-4080us.
I can't adjust the brightness of my monitor and it's soooo bright that it hurts my eyes. Tried using the function key but no response at all, please help~~

Hi Advance23,
Thanks for your reponse I appreciate that.
Yes, i have just reinstalled Windows 7 64bits home premium on mt laptop (and I believe it's the latest version and with most present updates). After the installation, all the funtion keys are not working, e.g. Brightness adjustment/volumn adjustment etc.
I did some research before posting this post and followed the steps on "Resolving Problems with the Brightness of the Display" from HP website to try to fix this as well, however i did not have much luck.
One thing I haven't try is to download the drivers for HP, as there are too many drivers out there im not sure which one to download, so if i'm going that way would love to have someone's professional guide of which one should I donwload in order to fix this problem.
Btw, since the system is newly installed the HP support desktop usually appears before going into windows is not there anymore, don't know if this is relavent to the issue here.
Please help me with this, I really need to get my laptop going but now with such a bright sceen I have to ware a sunglasses
Thanks

F5 and F6 keys (MacBook Pro) do not adjust screen brightness after upgrade to OS X Lion

Hi All,
since "upgrading" my MacBook Pro from Snow Leopard to Lion, the F5 and F6 keys for adjusting the monitor brightness do not work anymore! No matter how I set the settings for the monitor, the keys do not work.
Sometimes, the MacBook now just uses a low brightness and the only way to modify this is to open the system settings and change it there.
Does anyone know how to fix this so that it works properly (like in Snow Leopard) ?
Thanks,
Kristian.

The screen brightness adjustment is F1 and F2.
You can also adjust in System Preferences > Displays.

Cannot adjust screen brightness in Windows 8.1 on my G50-45

Hello there,
I just bought my new lenovo and instantly upgrade the system software into Windows 8.1.
Everthing looks fine instead of the screen brightness adjustment, i've downloaded the latest graphic drivers but nothing happened.
The display adaptor section into device manager keeps showing up that the driver is Microsoft Basic Display Adaptor rather than AMD radeon R2.
Thanks in advance guys.

hi kostas-mi , ecountered that issue a month ago and was able to resolved it
things you can try:
1- you can roll back the driver back to its stock state, if this doesnt work ,
2- install latest driver of your graphic card
3- This step will fix the problem:
- go to registery by regedit and change the value to 0xf048
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"FeatureTestControl"=dword:0000f048
OR
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
"FeatureTestControl"=dword:0000f048
Dont fake the funk............

Satellite A100 PSAA8E: Cannot boot from USB after Bios update

Hi
I downloaded the latest bios (v6) for my satellite a100 (psaa8e) and after updating the old bios, I noticed I can't boot from USB. Is there a way to restore the old bios or will this problem be solved?
Cheers
mo

I used to press F12 after restart and choose from USB. After downloading the bios, the system refuses to boot from the USB (external CD drive). However, if I place the same CD into the unit's CD drive, and choose boot from CD after pressing F12, the unit boots fine. This only happened after the bios update.
Thanx

Changes in screen brightness after Windows update

I recently purchased my Lenovo IdeaPad P500. The screen was fine until an automatice Windows update occurreced. Now it is hard to see the screen because it has darkened. No matter what I try I cannot get it to brighten up and it is hard to view in well lit rooms. What can I do to correct the problem. I have tried all of the googled suggested out there with no success. Please HELP!!!

I don't see where to turn off the auto brightness feature in Win 8.1 on P500 Ideapad.
But I think this laptop has other problems; the screen remains very dim even while booting up.
Help!

Computer HP Envy 17 Notebook PC - screen blank after bios Version F.53 update

Computer HP Envy 17 Notebook PC - screen blank after bios Version F.53 update
computer cannot enter BIOS but switches on and screen remains blank.
The power and wifi indicator shows.
Tried removing CMOS battery with no change
Tried removing battery, pressing on button for 40 minutes then starting again still no change

Hi farai, welcome to the HP Forums. If your computer appears to be powering on, but you cannot see the screen it may be a recoverable situation.
This document will help you diagnose the issue, it looks like you have already done Step 1 (hard reset):
Computer Starts but Screen Remains Blank (Windows 8)
If you get to Step 3, the options listed won't work since you indicated you cannot get into your BIOS. In place of Step 3 in that document, you can try to restore your BIOS using this method: Restoring the BIOS
If you get to the end, it says to call HP. If so, it is most likely a hardware issue and you should call support for more options: HP Technical Support, North America 1-800-474-6836. For all other regions click here.
I hope this helps. If you need any more information, let me know.

Satellite A100-590 PSAA9E freezes on Toshiba welcome screen after BIOS update

Hi.
Yesterday I did a BIOS update on my Satellite A100-590 PSAA9E-03Z00QGR with the appropriate flash:
http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_driver_details.jsp?service=EU&selCategory =2&selFamily=2&selSeries=153&selProduct=624&langua ge=17&selOS=10&selType=all&yearupload=&monthupload =&dayupload=&useDate=null&mode=userMachines&search =&action=search&macId=&country=all&selectedLanguag e=17&type=all&page=1&ID=58477&OSID=-1&driverLanguage=42
bios-20070709111839.zip
After the flashing procedure the machine rebooted automatically, but unfortunately it now keeps hanging at the Thoshiba welcome screen. Also pressing F2 or F12 won't change anything. It seems like the BIOS is corrupt.
I saw, that in the BIOS package are delivered two flash files (s10gm590.rom and s10pm590.rom). But just executing the SanAntonion10 BIOS590MP.exe a .vbs script is started that decides automatically chooses and loads a flash file. Maybe it chose the wrong one?
What shall I do now? Is there a way to restore the BIOS, or do I have to send my notebook in?
Thanks in advance
MAT

> Satellite A100-590 PSAA9E freezes on Toshiba welcome screen after BIOS update
What to say Marc. It looks like you have used a wrong BIOS version or you have updated the BIOS in wrong way.
You could try to access the BIOS and try to set the settings to default.
Dont forget to save the settings if you will exit the BIOS.
But if this procedure does not help, you will have to contact the ASP in your country.
Possibly the guys will try to flash the BIOS again with other special version.
Good luck
Greetings
