On the other hand, why have laptop manufacturers started supplying their
fully isolated PSUs with 3-pin connectors?

Because if they supplied them with anything else in the UK, you'd need to
buy an adaptor as well.

You mean like the lead that connects the three pin, 13A plug and
terminates in the two pin figure of eight socket used by 80% of the
laptop supplies in this room? I've got Euro leads for them, too, so I
don't need to use adaptors when I'm travelling.

The other two are wallwart supplies which plug into the wall and output
the right voltage for the computer.

I suspect there's been change in in legislation in at least one country
where the laptops are sold, ands it's cheaper to change the design on
all the units than make a different one for the offending country or
countries.
