Omnia II won't stay "off"

[buckyswider]

Hi all, got a new issue with the O2. When not connected to power, it doesn't stay "off". Well, for about an hour or two after disconnecting (sometimes less) it work properly. But then I hit the lock button to power down the screen, and within 1-10 seconds it lights up again. Then when it times out and shuts itself off, it lights itself right back up again.

I'm undecided whether this is a hardware or software problem. I wish there was a logfile somewhere that would list the event which caused the device to light up...

I guess my first try will be a factory reset (auggghhhh!!). But then I have to load all of my customizations again. Sigh.

Anybody have any clues or advice??

Thanks...
