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!

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

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

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:

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.

Dell Latitude E6520 fails to boot after Windows Updates

Hello,
I have a Dell Latitude E6520 that is not starting up after Windows updates. It installs updates and requests a reboot, after which it blue screens at the splash logo and reboots again. This goes on indefinitely. The only way to repair it is to boot from
a recovery disk and run:
dism /image:D:\ /cleanup-image /revertpendingactions
This is after running dism /image:D:\ /get-packages and noticing that several updates are still in an "Install_Pending" state. These are the kb's that are pending:
kb2982378
kb2978742
kb2977629
kb2976897
kb2973112
kb2972211
There were other updates, but those showed as installed. I would post the WindowsUpdate.Log, but I do not see a button to attach a file and the log is very long. Here is what I think is relevant towards the end of the log:

Profiles being reset after windows updates?

Hi All
I'm having issues with Outlook 2013 SP1 resetting our users profiles after Windows Updates have been applied. Their profiles are being reset whilst their previous profiles are being renamed to "BACKUP of <profile name>".
Office 2013 x86 has been deployed via VL Media onto Win7 x64 machines and we are distributing the ImportPRF registry key via GPO (set to Update) in order to customise the profiles on first run. (basic email account and attaching a default PST file)
It appears that after windows updates are applied outlook is triggering the first run process again and therefore resetting the users profiles back to the standard set in our PRF.
We used this method to configure Outlook 2010 and for the years of deploying Office 2010 we never had any issues. Can anyone suggest what might be going on here or what might have changed in Office 2013?
Thanks

Random changes in screen brightness every few minutes (while working)

I am beginning to become unhappy with my new Thinkpad Twist. The laptop was just delivered and no changes to the setup were made.
The screen brightness changes while I use the device in an unpredictable way which is just annoying to me.
I prefer to work with full screen brightness and disabled the energy saving settings that would dim the screen after some minutes of inactivity. Still the screen just dims from time to time (also while I a am working) and also changes back to full brightness in a similarly unpredictable way. Those changes in brightness might take some minutes between them...
Do you have any ideas what software settings I should consider?
Also, the laptop appears to have an ambient light sensor. Could those changes in screen brightness be related to this sensor? FYI: Light conditions remained the same, no turning on or off the lights. Covering the position of the sensor did not induce any reaction.
Any ideas?
Solved!
Go to Solution.

Took me a while to find this but I believe this is the order of menus, links and drop downs to get to this feature.

Satellite C55-A5182: screen flickers after windows 10 upgrade....help!!!

Hi there , Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions. I read your post on the HP Support Forums and I understand that you are having an issue with the Touchscreen on your HP Notebook - 15-ac020nr. You had mentioned that since your Windows 10 Upgrade, it no longer works. Have you tried doing all updates (Windows, HP Support Assistant, BIOS)?Have you tried restarting the Notebook a couple of times?Have you tried to run the Windows Troubleshooter? 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 for Windows 10. The HP Support Assistant will also help find a proper driver for you to use. Updated Windows 10 drivers will become available on the HP Drivers and Downloads Page for your product. They will be released as they become available to HP. I did find a troubleshooting document for you called Touch Screen Issues. Although it does say it is for Windows 8, it will still work for Windows 10. Please follow the provided troubleshooting steps and re-post with the results. Have a great day!

SP 2010 - Getting "An unexpected error has occurred. " message when accessing Sharepoint site after windows update - Windows 7 Home Premium

Hi,
I am new to SP 2010. I have installed Share point 2010 server (trial version) on my Windows 7 Home Premium Laptop by following the below link.
http://msdn.microsoft.com/en-us/library/ee554869%28office.14%29.aspx
Everything went fine and was able to see the new sharepoint site after completing configuration wizard. SP2010 Central Admin also worked fine.
However, after windows update, sharepoint site is not working. I was able to see the site working for more than a day before windows update. SP2010 Central Admin is still working. Executed "PSCONFIG" after
update but still no good.
I saw a warning "The Security Token Service is not available" in Central Admin and did some research to fix the issue but nothing worked.

I am unable to change my screen brightness using the fn+F2/fn+F3 keys. I understand that it can still be adjusted differently but I want this way to work.

The F1 and F2 keys control brightness. Depending on how you have your function keys set up, you may have to also hold down the fn key to activate.

Windows Update Error 800B0109 after Windows Update Agent 7.6.7600.320 Installed

Hi, I have this error message when running windows update, it happened after Windows Update Agent 7.6.7600.320 installed.
Any idea how to resolve this?
Thank you.

Hi，
Please make sure that your antivirus application does not scan the files in the
%windir% \SoftwareDistribution directory on any computer on which Windows Update Agent is installed.
You can also temporarily turn off the antivirus application and check the result.
Or run the following commands, and press Enter after each command:
Net stop wuauserv
cd %systemroot%
Ren SoftwareDistribution SoftwareDistribution.old
Net start wuauserv
Try to install updates again.
