<human>: Give me a shortened version of the text

First off, NO it was not stolen.  A friend of mine works for an airline at the regional airport in my city.  A few months ago, while cleaning out the passenger cabin after it had landed, he found a HP Mini in the back of one of the seats.  This plane was also coming from a major hub for the airline, so the passengers were from all across the country.  He gave it to the lost and found, nobody claimed it for the standard period plus a few days, so he was free to take it home.  He tried to get into it, and being not-so-tech-saavy, let me take a look at it to see if we could find the owner.  The username didn't give us any clues, there was nothing else besides the Mini itself in the case, not even a charger.  Using a visiting friend's charger, I've tried various ways to get into the system, and could not find any information for it's owner.  I've even attempted to find the owner via S/N and through HP Support, nothing.  So, after a few months of trying to find the owner, and my friend going back home, I now have a homeless HP Mini with a dead battery.  What could I, or should I, do with it? Get another charger and keep on trying? Wipe it? Sell it?
