Nokia service has instructed me to take my battery in and out of the device repeatedly to fix my "not powering on" issue. I'll keep you posted. My N800 is not yet "bricked" but turns on only when plugged into the charger. I will last several days on standby mode, so it still works. The bummer is that it won't start up into "software update" mode so I'm stuck with OS2007.

Nokia support also asked me to explore my "exchange and return" options with my retailer. Buy.com's 14-day return policy isn't helping me at this point.

I'll keep you all posted.
