Step 2: Go to a temp directory (like cd\temp)
Step 3: Type powercfig /SleepStudy

- Notifications. Even while sleeping, the Windows notification system (WNS) does stuff. Turn off as many unnecessary notifications as possible.

- Your network card. Make sure you have the latest firmware and network drivers.
