I've connected an external keyboard to the laptop. The laptop is a dual boot. The external keyboard is identified under Windows (it is also identified as primary keyboard if connected through PS2 port to the tower, but isn't identified when connected through USB to the laptop. Laptop doesn't have a PS2 port, so I can't test with it.
PS. It is a somewhat "difficult keyboard (steelseries), but works on the deskop fedora, as mentioned above.
