FWIW, I'd unplug the fan before doing that. The suction from the vaccum
causes the fan to rotate, and in turn generate (a small amount of) power.
That power is fed into the fan controller where the controller expects
power to go _towards_ the fan instead of coming in, maybe damaging the
controller. I don't know whether that's still an issue with modern Thinkpads
but better safe than sorry.
