I recently obtained one of these, and so far everything is great except I’m having a problem with the included port replicator.
The AC Adapter works with it fine, and same with the speakers and USB ports, but the computer doesn’t recognize that the replicator is plugged in, so I can’t access some of its other functions.
A port replicator is a thing you can plug in to certain laptops that has a whole lot of ports on it. (Usually different than the ones on the laptop itself)
