New W520 cant adjust screen brightness!

Hello,
I am new to the forum and new to lenovo.
Just started setting up my brand new w520 and the Fn+Home/End keys dont work to control display brightness.
Any w520 owners having this problem as well?

@johnt7225,
Appreciate if you could try running TVSU and Windows Update to ensure all the drivers are installed.
Also is X-Rite a default software which comes with the W520? (I am unable to confirm this as I do not have a W520 to test on) ...
If X-Rite is the one acting up and causing the screen brightness adjustment to not work, I would need to escalate this to engineering.
Thanks Johnt725.

Lenovo P400 cant adjust screen brightness

Updated to windows 8.1 and now can not adjust my screen brightness on my Lenovo P400. I tried updating the display driver through the device manager and it told me there were no available updates.

Hi,
Have you tried the method above for test?
Generally speaking, this problem probably caused by Graphic driver problem, please check and make sure your Graphic driver is compatible with Windows 8.1.
In addition, also make sure your motherboard and chipset driver was upgraded to be latest.
If possible, also please upgrade your BIOS to be latest.one
Be warned.
Flashing BIOS is a risky process. If power is interrupted during the update your machine will be rendered unusable.

Cant adjust screen brightness

Can somebody 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

Adjusting screen brightness and contrast on Satellite L550-113

I am a visually impaired user and I'm thinking of purchasing the Satellite L550-113, but before I do that I need to be sure that the screen brightness/contrast can be adjusted very easily, preferably via hardware controls as opposed to via the control panel. I also need to be sure that one can make the screen quite dull (i.e. too dull for a non-disabled user).
Could anyone give advice on how to adjust the screen contrast and brightness on the Toshiba L550-113? Also, does the screen have a glossy or matt finish?
Any general information on the quality and ease of use of the screen will be extremely useful and highly appreciated! Thank you.

Hi mate!
Yes, the screen brightness can easily adjust via FN keys. You have to press FN+F7 to increase the screen brightness and FN+F6 to reduce the screen brightness. Furthermore in Vista power management you can also adjust the screen brightness and save the settings for different power profiles and on batter or on power mode.
As far as I know Satellite L550 has a gloss finish screen as other Satellite notebooks.
I hope I could help you a little bit! :)

Issue with blank screen HP G60-447CL Notebook PC

Issue with blank screen HP G60-447CL Notebook PC, I purchased warranty and have had the laptop serviced before for the same exact issue. Same problem has come up again blank screen it has been less than five months this problem was fixed and it has started again: blank screen white, laptop is powered on nothing else happens. Now I cannot reach anyone.

You're very welcome.
I have tried many times to help folks with different drivers and nothing has worked.
I'd say at least a dozen people have posted about this issue, and no one can fix it.
I don't understand it either.

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.

Hp g6 pavillion notebook causing cooling fan issues

Hi There ,
My HP g6 pavillion notebook says the cooling fan has had some issues which will lead to bad behaviour and loss of data if continued .
I head some heavy noise from the bottom of the notebook and looking for a solution for the same.
Thanks.

I understand the fan makes a noise sometimes and not function properly. I apologize for the late response, but please know I will provide you with the information you need!
First of all, here are some official instructions you can try that could help reduce the noise that the fan makes: Reducing Fan Noise
Some steps included are updating the BIOS and changing power settings. I believe these steps will help you out.

Adjust screen size

When opening photoshop elements it appears about 3 inches wider than my monitor making it impossible to access tools, albums and so forth. It is also taller than the monitor, so can't grab the top to move back and forth. I am not having this problem with any other program on the computer. How can I shrink it down the photoshop to fit the monitor size?

If all your applications are showing this, you probably have to adjust screen position.
Computers vary on how to do this, some have automated controls to adjust the
screen position. Looking in the help section that came with your computer should tell
you.
If the problem is just with elements, make sure the application is maximized.
