What is the difference between using a grounded ethernet cord vs a grounded laptop usb adapter to ground a laptop?
Are they both effectively the same in results? Is either preferable? I have an internet switch that is plastic and so far, ungrounded. The laptop is a few feet away from me but I have a keyboard and monitor attached to it. I do have a phone a foot away from me that is attached to an Ooma (little linux computer) with a phone cord, that is attached to the ungrounded switch. My monitor uses a grounded power cord, so hopefully that is fine. Does the monitor serve to ground the laptop?
