Windows 8 Pro Upgrade Problems (Switchable Graphics, Screen Brightness Adjustment, etc.)

Hi guys! I hope you can help me with this.
My laptop is a Lenovo U400 bought last April. I upgraded it yesterday to Windows 8 Pro.
The Upgrade Assistant detected incompatibilities on the following softwares (I'll be mentioning only those I had problems with after the update.)
-AMD Catalyst Install Manager
-Catalyst Control Center
-Lenovo Energy Management
-Cypress Trackpad
After the update, the following problems occurred
-Windows kept prompting me about the incompatibility of Catalyst Control Center and Lenovo Energy Management
-When I check the Device Manager -->Display Adapters, My AMD Radeon HD 6470M was changed to HD 7400M and has an exclamation point on it indicating a problem. When check Properties it says, "Windows has stopped this device because it has reported problems. (Code 43)"
-I can't manage switchable graphics because the AMD Radeon driver has been stopped by the OS and Catalyst Control Center doesn't work. It says, "Catalyst Control Center cannot be started. There are currently no settings that can be configured using Catalyst Control Center."
-My touchpad works but does not support multitouch functions.
-Screen brightness adjustment stopped working both on hotkeys and Power Options.
I tried the following actions to fix the problems:
-Downloaded the new softwares from Lenovo Support but the Catalyst Control Center and Cypress Trackpad still doesn't work. I also tried installing driver software from the AMD site but it still didn't work. [FAILED]
-I tried to use the Cypress Trackpad software for U300s/e and it fixed the problem with the touchpad [FIXED]
-Installed the Energy Management software for Windows 8 but when I click the 'Optimized Battery Health' button, it keeps reverting back to 'Maximum Battery Life'. [PARTIALLY FIXED]
-Resorted to 3rd party software to fix the Switchable Graphics (Catalyst 12.11 Beta from leshcatlabs.net) and it fixed the switchable graphics problem as well as the Catalyst Control Center problem. This is temporary until a working solution or update is available. [TEMPORARILY FIXED]
-All actions trying to fix the Screen brightness adjustment didn't work. [FAILED]
Please do help me on this. Thanks in advance!!!

Yes I own U400 too and I'm using it now. To many forums been read, can't remember which one. Basically, u have to clean AMD and Intel drivers that come along with Win 8. Why? Because the Win8 driver database will lead the device ID "DEV_6760" (if you looking at display adapter device properties) to HD 7400 series instead of HD 6470M, again why? At the bigining only the HD 7400 series already "certified" by Microsoft, while the 6470M out of somewhere. Current CCC (or else) + 6470 drivers, contain also driver for 7400 series in same packages (at least until now, hopefully near future they will release an update). So you can gues where the windows will lead to? Yes 7400 series (certified one). This will explain also why the Energy Management didn't work to= "missing identifier" or we can say "hardware not match".
You have to find a "fix" driver which contain only HD 6470M and install it manually trhu "Have Disk" option, after you claan all AMD and Intel driver. If you success, then install the CCC from Lenovo Support and from ATI ( I use 12.11 Beta8 Net4 CCC - this is a must), but remember to unchek the AMD Display driver when you install both CCC, and leave the rest checked including Intel Component. Then you can download install anything you want =).
Leschat's driver did't work on my and "harm" the system. Believe it or not, I found the AMD 6470M standalone driver on HP website. They call it "SoftPack", which actually contain CCC software.
It's quite tricky thing, that's why not everyone willing to try. But I think it's worth to try, as the risk is not too deep, just backup anything befor you do it. Cheer

Windows 8.1 kills screen brightness control

I have a touch smart 23 computer that came with windows 8.0. An auto upgrade to 8.1 caused the screen brightness control to stop working and the screen stays on super bright. I could not get a response on how to fix so I had to re-install 8.0 which fixed the problem. I set the system to not upgrade without my approval and yet it did it again last week (about 4 or 5 months later). When I have to reinstall 8.0, I have to re-install several primary programs as there are no restore points left except back to factory settings. Question one is - has there been a fix installed on windows 8.1 that will again let me control the brightness on my screen? If not, question 2 is how did the update override my setting to not allow updates to install without my approval. I have a full day of re-installs that I don't want to have to do a third time.

Hi:
You probably have to install the W8.1 graphics driver for your specific model.
Normally when you can't control the screen brightness, that means the graphics driver isn't installed.
As for your second question, that I do not know.

My screen brightness control buttons don't work windows 8

my screen brightness control buttons don't work?
the light in the mute button is always on when NOT on mute?
Have set up Win8 3 TIMES but get always same bug agan
Hope someone can help

Hello smarisig. I understand you are not able to control screen brightness from the keyboard on Windows 8. By chance, did you upgrade to Windows 8 from Windows 7? I have located an online forum that contains troubleshooting on this issue: http://thedailybuggle.com/forum/unable-control-screen-brightness-windows-8-a-200.html
The person who posted the issue on this forum had upgraded from Windows 7 to Windows 8, and then this issue occurred. That is the reason I asked if this Windows 8 was upgraded. Regardless, follow the troubleshooting presented and it could resolve the issue for you. If not, let me know and I will continue to research the issue in the meantime. I'm only here to help!

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.

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 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

Using Windows 7 Display Won't Adjust Screen Brightness

I am running Windows 7 Home Premium Service Pack 1 running on my MacBook Pro from January, 2012. My screen will not adjdust brightness. Not using the F1 & F2 hotkeys (The window will pop up showing I'm pressing up and down on the screen brightness but nothing changes) even going in to Windows 7 control panel will not change this. I can't change the brightness or turn off the display with the hotkeys or in Windows 7 settings. I have BootCamp installed. Any body have the same problem or know how to fix it. I've tried updating my graphics drivers but I don't think it worked.

Take it to the Genius Bar. Your SIM might have an issue. The SIM is the part that manages power. My brother's Macbook Air has this issue. What haapens is the SIM malfunctions and gets confused on how much power to send to each part. Other symptoms include fan always running (even when its been off for a while), and you can't adjust the screen or keyboard brightness.

Adjust screen brightness Windows 10

I have a HP Spectre x360 - 13-4009na and have just upgraded to Windows 10. The problem is I cannot alter the screen brightness using any of the usual methods. - The fn buttons do not work- There is no brightness control displayed on the Control panel - Power Options- The Calibrate Display Colour method fails with an error while "... preparing to calibrate ..." - "Unspecified error". So my display is set to high brightness and I cannot change it. Please can someone help? Thanks, Paul.

Omg, I had the same issue too. I kinda tried changing it with the AMD driver (that I had to re-install after the Windows 10 update) it was pre-installed when I first got my laptop, anyway besides the point, I used it and it kinda changes your brightness, but not the same way as using your brightness control buttons to. I hope that helps much, It didnt exsctly satisfy me. But the AMD driver (if you have a laptop) is a great driver that runs your graphics really smoothly

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
