Yes, the big search for an open outlet. I always assume that the cleaning crew has to plug their machines in somewhere, so I generally look along the wall near the jetway door, or on a central column. It really varies from airport to airport. I also look for someone sitting on the floor with a laptop, often a sign that they've found an outlet. I always thought someone could make a fourtune setting up metered kiosks that you could put a quarter in for 30 minutes of power.
