I have used the command 

powercfg -lastwake

to determine what is waking up my computer. Here is what it produces in prompt

Wake History Count - 1
Wake History [0]
  Wake Source Count - 1
  Wake Source [0]
    Type: Fixed Feature
    Timer Expired (RTC)

Next to Type: it says Fixed Feature. I assume that means something internal. Also when I run the command 

powercfg devicequery wake_armed

nothing is printed out in prompt which further reinforces that idea that something inside the laptop is waking the laptop. I have a battery that holds a charge for no longer than a 30 seconds to a minute but I am leaving the laptop plugged in after putting it to sleep.

I have also looked into my Device Manager and made sure that "Allow this device to wake the computer" was unchecked on every device that has a Power Management tab.

Another thing I did was go into Power Options > Advanced settings > Multimedia settings > When sharing media > Plugged in: and changed that option to "Allow the computer to sleep"

  • the RTC flag seems to suggest some Scheduled task item. Is it always one minute exact? Does the event viewer show anything for that time? Got any trialware that ended? I assume if it is 1 minute everytime, that it never goes back to sleep? – Psycogeek Mar 06 '12 at 22:36
  • Here is a similar , http://www.vistax64.com/general-discussion/187088-vista-spontaneously-awakens-standby-3.html see the second to the last post. Looks like it BREAKS it altogether. Myself I would not do that , unless I had at least a registry backup first. or the steps to undo it. – Psycogeek Mar 06 '12 at 22:45

Apparently all I had to do was enter the BIOS and disable the ability to wake the computer from incoming network data. Now everything is fine.
