i think if you leave the third prolonged (grounding) plug thing hanging, you should still be ok. just make sure the laptop's power adapter can handle uk voltage (220volts?). it should say - on your laptop's power thing -- something like "AC 100-240V".

hah, my electrical engineering degree is paying off!!

no warranties, though, explicit or implied, of course (and that was my mba;)

have a blast on the other side of the other ocean!!!
