Ah well.  That's probably the issue then :-)

Having never used the laptop under anything than Linux I guess I can't
say for sure whether it works under Other Operating Systems. I think it
is unlikely I will be going to the trouble of installing Windows on it,
but the laptop seems generally pretty good so I suspect there may be
some more around the office, and I might be able to get hold of one
briefly before Linux is installed.
