Re: Y450 dolby home theater key doesn't work

un-install both one key theater and power management, restart your computer, install home theater, then power management ( make sure "utility" checked )

Re: Y450 dolby home theater key doesn't work

check the folder drivers under volume d: ( d:/drivers )

make sure you installed latest sound drivers and also you may need this.

Re: Y450 dolby home theater key doesn't work

there's no drives folder in my D:

maybe you refer to the y450 systems bundled with windows 7?

i bought the dos bundled y450 and i got the driver's cd for vista then i install the windows 7(also partitioned it) so i came looking for windows 7 latest drivers in the lenovo page

o also,

is it one key theater or dolby home theater??
