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 6 '12 at 22:36
    
Here is a similar , vistax64.com/general-discussion/… 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 6 '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.
