Gavin,

Perhaps with newer systems this is true, but I have noticed this problem when using a transformer as opposed to having an internal switch on the system to change over.

Don't forget that the Hz will probably have an effect on the fan, disk drive and other peripherals.

While the 50Hz effect will be quite noticeable with any device that operates
with an AC synchronous motor (the canonical example being an electric razor),
I seriously doubt that your laptop derives its 400MHz clock by dividing down
the 60/50Hz AC line frequency.

Your laptop will run at the same speed in Europe as it does in the US.
