Y450 One Key Dolby home theater does not work

[ Edited ]

hi

 

i have a lenovo y450. I just got the windows 7 upgrade and installed it right away. windows 7 is great! i just have this one issue. The onekey dolby home theater touch sensitive button on top does not seem to work. all the other buttons (onekey theater, mute, volume up and down) work fine. its just that one button. But the dolby control center program is installed. i can only access it through the start menu. can anyone help me resolve this? thanks

i thou it was about drivers but, it seems not.

then it's all about upgrading to window 7. while using vista there's no issue.

i'll search for the solution, and if i find, i'll let you know.

also where can i get the dolby software? i downloaded the file named dolby in the drivers page for y450. then uninstalled the dolby software hoping that when i installed the dolby file from the y450 drivers page that the button will work. i installed the file named IN2PCH01WW5 (dolby file from the drivers page) nothing happened. and now i dont have the dolby software...

uninstall dolby application you run, and run this again : http://consumersupport.lenovo.com/en/DriversDownloads/drivers_show_1734.html

 

if this doesn't work,  use system restore.
