the fn keys work(brightness and everything works fine) with power management win 7.but the dolby key stil not working

and i didn't find the utility option during the installation

if you install power management windows 7, there'd be no utility selection.

your fn keys working now, lets skip this now.

un-install one key theater, restart your computer install it again.

make sure you have already installed sound drivers.

it WORKED NOW!!thx for your help yigit

it seems that after the installation of the one key theater and the power management win 7.you have to install the dolby(i'm lucky trying this) software from the lenovo website after it said that the software is installed go look for the C:\\drivers(seems all that driver installation were automatically backed up after installation in one folder) and inside the dolby folder run the dolby for 32_64.and restart and voila!!

thx!
