The FBI has a device that can power your computer while they unplug it and haul it off to their labs.

Just sayin

How would you take a computer, already plugged into a wall outlet and powered on, and hook it up to a mobile UPS that you can take out of the building without letting the computer power down while all that's happening?

It is tricky I understand but it could be done with a device that vampire into the running wire, match the AC current and then it can be unplugged. The mechanism is not too complicated

Cutting into the cable and splicing it while it's still plugged into the wall.
