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

[beyri]

what do you mean by utility checked??

[yigit]

there is an option "utility" on the installing process. make sure it's checked.

[beyri]

after uninstall both the one key theater and power energy management and restart,you said install home theater.do you mean the one key theater or the dolby home theater?if it's dolby. i can't find the software in the lenovo y450 driver's page

[yigit]

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

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

[beyri]

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??

[beyri]

o yeah i found this(unrelated to the above problem)

one key theater and dolby home theater is the same application.
