I guess an example for what sthen@ wanted to say is that most laptops
have an external power adapter - for example, the one of the machine
i'm currently typing on has
INPUT: 100-240V~ 1.3A 50-60Hz
OUTPUT: 20V= 2.25A
printed on it (transforming AC to DC), so the machine itself
does *not* have an AC input. Instead, the "external power" the
machine receives is already DC.
Yours,
Ingo
