All docks can operate without power plugged in - most of ports in docks are powered from the laptop (in this case from battery). Plugining power will hower make possible to charge battery and directly power devices. Port Replicator I, II and Mini-Dock will be all fully functional - power supply is only used to charge laptop battery and power it. Dock I and Dock II, without power-on will additionall do not have working PCI, CardBus and UltraBay slots. USB hub can also be not powered and be not working, or refuse to power much than one port. In all models, simple passthrought ports (LAN, WAN, DVI, VGA, COM, LPT, PS/2, AUDIO, FDD) doesn't need any additional power. Connected USB device or floppy drive however can drain laptop's battery faster.
All docks have also Kensignton lock.
