Please help!! I'm taking a flight from O'Hare to Narita later this week. Can anyone tell me exactly what kind of cord/plug-in device I need to hook into United's "Empower" or whatever it's called now allowing me to get power for my laptop. I use a Hewlett/Packard Omnibook 6000. I went to Radio Shack and they seemed fairly clueless. If anyone can tell me a precise brand or model, that would be enormously appreciated. Also, any estimate on how much it should cost (in general terms) would be helpful -- I don't want to get taken! Thanks.
