My P5Q Pro Turbo went to sleep in mode S1 without having installed Asus s/w. Waking and sleeping is excellent compared to Win XP. LAN and audio drivers that came with Win 7 worked well. If you have the time you may want to uninstall Asus drivers and see if WIn 7 drivers work.
Download the latest AIsuite, extract , go to folder open Setup.exe with right click and chose Properties. Then go to Compatibilitiy and chose × Run this program in compatibility mode for : Windows Vista ( Service Pack 2 ) and under Privilege Level apply × Run this program as an administrator.
When still not going try with × Run this program in compatibility mode for : Windows Vista or Windows Vista ( Service Pack 1)
I just wanted to point out that you may have trouble installing AI Suite under Windows 7 if Stickies (Stickies) is running.
I tried following all the instructions regarding compatibility mode, administrator privileges, installing the ACPI driver, etc. Yet when I tried installing AI Suite, the installer would stall at 0%.
Strangely, this was solved by closing Stickies during the installation.
You need to install a different version of ai suite. here's the link ASUSTeK Computer Inc.-Support- Scroll down,choose the newest version , install and enjoy.
