2013-01-13, 22:08 PM

dear sir,

i have an ideapad z580 laptop with windows 8 64 bit installed on it, my drivers are up-to-date but when i touch the dolby switch on/off button in front of the screen just in front of the brand lenovo my dolby theater software doesn't recognise. this button highlights when i touch it but software doesnt respond to this button. when i had the old versions of drivers it was working but now it doesn't work.

Welcome To Lenovo Community


We are really sorry to hear about the issue you are facing,  


Please try reinstalling the drivers Dolby Home Theater, The drivers are available in the driver package

After unpacking the package under driver’s main folder you will have a folder by the name Dolby Home Theater V4 . Run setup from there , once setup is completed restart the system and check




Do give this a try and let us know  




Hope This Helps

The Z580 does not have a Dolby Button, it does have a OneKeyTheater button, looks like a video camera, and re-installing the Sound/Dolby Software will do nothing, you need to install the OneKeyTheater software.


I purposely uninstalled the OneKeyTheater software as i don't like it, and the touch button no longer does anything, but the Dolby V4 works great.


EDIT : I cannot find the OneKeyTheater software on the Z580 driver/software page? , but it should be on your D: partition or from the link i found below.
