Z580 fn+F4 and Cap sensor buttons are not working

Hello,

I have an ideapad Z580 laptop running Windows 7 (preinstalled)  and I have two problems:

         *1* The "Cap sensor buttons" don't work anymore

 

          *2* The combination of 'fn+F4' which is supposed to open the interface for display resolution settings.
                Doesn't work anymore too...

 

I guess the matters come from the drivers, but I don't know which one I am supposed to install.

 

Do you have any solutions?

 

Thanks in advance

Re: Z580 fn+F4 and Cap sensor buttons are not working

Hello,

 

 

 

For fn+F4, yes windows was preinstalled. But it is windows seven

 

"Cap sensor buttons" is the number 7 on the picture in attachment.

                   by not working, I mean there are no more light and nothing happens when I touch them.

Well, We just need you to reset the BIOS and there is an application called Lenovo Energey management you will need to uninstall it if already installed, Below is the link of the latest version .

Re: Z580 fn+F4 and Cap sensor buttons are not working

Hello,

 

In order I reinstall "lenovo energy management"

then i reset the BIOS

 

But it doesn't change anythings.

 

Note: When I press Fn+F4 I got a message "the video card driver is not installed on your system"

But when I go in the "device manager " both of my Video card have their driver up to date
