Just a wild guess, but some computers can be configured to wake up when either USB or network activity is detected. Perhaps something is "pinging" your computer and causing it to wake up to handle it.

Check your BIOS configuration for something like "Wake on LAN". There might be a similar setting for USB activity. If there is, make sure they are turned off (unless you actually need that functionality).

D’oh! I see that you already did that. Never mind!

That’s what I was wondering- Would a printer in the off mode still ping the computer? We just installed a new laser printer not too long ago (And I can’t remember if the problem was happening before- I think it was but can’t be sure) I suppose the way to tell is to unplug printer completely

I will, but nothing other than the printer install has changed on the computer- no updates recently, nothing really-

Excellent point! WOL could be the culprit.
