In my case 3 laptops are connected to the switch. It works fine most of the time, but there are times when I'm switching between my laptops and my keyboard locks up (all the lights come on). Where do I have to disconnect and reconnect it to make it work? Sometimes when I switch from one laptop to another, the keyboard doesn't work, I can't type. I need to switch to the previous laptop and back to the one I want to work on. Also annoying is that I have one of the laptops with two external monitors, one on the switch, the other on the external. When I disconnect, all information displayed on the switched monitor's screen is transferred to the external monitor. I had a 2 port switch and never had this problem. I am thinking of looking for another 4 port switch.
