MBP randomly wakes from sleep

I have a new MBP that randomly wakes from sleep when I plug it in to a power source. I haven't been able to figure out why and when it does it - it seems sporadic. Right as you plug in the magsafe and it lights green or red, the apple glows and you can tell the screen is on, then ~3 seconds later it goes back into sleep.

Then, after you open the lid, you'll have to put in your password twice in order to get back to the OS (e.g. I put in password, hit return, then the password box just pops up again and I enter it again and it lets me on).

Not sure what happens if you don't have a password. I'm on Leopard and current on updates. Anyone else experienced this?

same here

if you have any sort of BT devices connected to the computer, make sure you uncheck the box that allows bluetooth devices to wake the computer from sleep
