How can I unset the "quiet office" pc mode in windows 7 ? I don't find it.
You'll likely find it under "Power Options" or "Battery Settings" in the hardware section of the Control Panel - it may be named differently; mine was set to "HP recommended" for instance - set it to "High Performance" and see if that helps. I think it improved my performance a bit, although the mouse is still frustratingly jerky.
