Re: Can't adjust brightness in Windows 8.1 for IdeaPad Z400

HI,

 

I tried to install that driver to my Z400 Lenovo laptop however a pop-up screen is showing saying "This computer currently contains driver versions newer than the versions you are about to install."

Should I overwrite this?

Would appreciate your immediate response Smiley Sad

Yes, accept it, and you will solve the problem.
And to me it was unusual, but it worked.

Good luck

Hi Oreotumalad,

 

Welcome to Lenovo Community!

 

As the current version of driver is already installed in the computer, please un-install it and then install this version of driver to get the issue resolved.

 

Do post us back if the issue still persists.

 

Best Regards

Shiva Kumar
