MacBook Pro spontaneously wakes from sleep after upgrading to Leopard?

For some reason, after I upgraded to Leopard, then whenever I put my MacBook Pro to sleep, it spontaneously wakes up after some time

I don't know why this is happening, but I know for sure that it's related to Leopard since I put my laptop to sleep every night (it's in my bedroom) and after upgrading to Leopard, it started to just wake up a short while after putting it to sleep.

At first I thought it could be Time Machine, so I disconnected all my external drives, but that didn't seem to work.

Does anyone know why this is happening? Thanks in advance!

You have nothing connected to the Mac except the power cord? I had the same experience with Tiger when I hadn't turned off the Bluetooth mouse. Bluetooth wakes the machine from sleep. Perhaps you have some BT peripherical or wireless-something that wakes it up. Just my ideas...
