The one time I've had anyone take a closer look at my computer equipment was an old iBook "yo yo" power supply. But that was a weird design for a power brick and not exactly a popular brand at the time. They probably looked pretty strange on an xray. On the other hand I don't fly often, so I'm not much of a data point.
