Or, sometimes the WBC power outlets just don't work! I bought a MacBook Pro (which draws 85 watts max) and have taken it on two WBC trips so far, both on 330s. On one flight, the seat outlets in my seat wouldn't power anything... not my iPod, not my MacBook, not my ThinkPad. I had the same symptoms as the OP. On the second flight, everything worked fine.
