INTRODUCTION

By default, Microsoft Windows XP and Microsoft Windows Server 2003 enable auniversal serial bus (USB) keyboard and a USB mouse to wake a computer 
after the computer goes in hibernation Other types of USB devices can be enabled to wake the computer if you click to select the Allow this device to bring the computer out of standby check box. You can click to select this check box on the Power Management property page in Device Manager.

When a USB device is enabled to wake the computer, the default behavior permits the computer to enter the S1 system power state for standby. Standby is not the S3 system power state. The S1 system power state is a "lighter" system power state than S3. The S1 system power state typically conserves less power than the S3 system power state. 


By using the USBBIOSx patch, you can override entering the S1 system power state as a default behavior when a USB device is enabled to wake the computer:
