Somewhat different question: I just flew RT IAD-MCO on a 737, both trips in first. On neither flight did my outlet work; I was trying to charge my dying laptop both times. Both times the green light was on. I don't often use the outlets; is there a trick I"m not aware of? Do they not work to charge laptops but only smaller devices? Or did they just not work (it's conceivable this was the same aircraft in both directions)?
