Windows 7: Sleep doesn't

Sleep doesn't

Twice now I have put the machine to sleep, checked an hour or so later that it is indeed suspended, but found sometime later when I return that it is running. When I check the system log, I can't see what has caused the machine to resume - eg for last night I see a message in the system log at 23:01 "The system is entering sleep.", followed by a couple of messages about services entering the stopped state, and then at 03:00:

"The system has resumed from sleep.

Sleep Time: ‎2009‎-‎01‎-‎27T12:01:33.141601600Z
Wake Time: ‎2009‎-‎01‎-‎27T16:00:13.645507800Z

Wake Source: Unknown"

Hello Nick,

Do you have a wireless mouse/keyboard. I have had turning on my tele. wake the computer since I go a wireless mouse. Me turning the phone on while next to the comp.

Also could be from a network card. Go to device manager and then to the properties for these devices. Look for a 'Power Management' tab and deselect 'Allow this device to wake the computer' for as many as you can. See if that fixes it.

Try opening CMD with administrator rights and typing

powercfg lastwake {enter}

Does it show the same ? unknown wakeup source?

To answer the various suggestions:

Neither mouse nor keyboard are wireless.
Option to allow NIC to wake computer is unchecked and greyed out.
powercfg lastwake shows "Wake History Count - 0" - don't know if this count is only since the last full poweron, as the PC has been completely shutdown and restarted since the problem I reported.

This installation of Windows 7 was done as an upgrade from a Vista Business installation that could be put into standby without ever waking spontaneously.

I'm pretty sure that it is since the last shutdown.

Have you tried going into advanced power option and disabling the USB selective suspend setting?
