I am currently in another country and want to make sure the DROID stays powered off so I can't possibly ROAM. However, when I plug th charger in, the DROID wakes up and fully powers up. I have set airplane mode so hopefully the phone is off, but why won't it stay off? I press the power switch for a few secons, do the power off and confirm it. The DROID powers off and then a few seconds later powers on again.
