I posted this stuff on one of the other theads, on this board. Even though it is written in a possibly humorous way, it is true and if you do use your laptop in the bathroom. please read, at least the first paragraph.
There has been some discussion of board members using their wireless laptops, to participate on the board, while sitting on the toilet. Most toilets are connected to a grounded water and sewage system. I would advise those members to be running their laptop on battery power and wireless Internet only, while sitting on the pot. Unless you have ICE 60601-1 approved battery charger/eliminator and your bathroom is also wired to that standard you are putting yourself in a life threatening position. You do not want to shock the shit out of yourself. The people of this board know a better way to facilitate the transport and relocation of feces => ENEMAS
This second paragraph is part of a discussion between gazeebo and myself. It talks about the reason (again in a tongue and cheek manner) to not use an Ethernet cable, for net access if you are going to use your laptop around water. The basic premise of this information is based on the safety standards hospitals have to use when connection or just using their electronic equipment to or with patients. Believe it or not hospitals kind of try not to kill their patients most of the time.
Your Ethernet cable can kill in a couple ways. I think the signals are transformer coupled (to prevent ground loops and as a high pass filter to reduce the bandwidth of the radiated noise. (the FCC is watching you!) I think power over Ethernet can have a maximum value of 25 volts. (limit on unshielded plenum cable). I am not sure about the 5 volts @ 500 ma you talked about. So normally you could possibly end up with 25 volts touching the end of your pee-pee. I bet you would move you pee-pee away from the 25 volts rather quickly. But on a bad day the isolation, of the power over Ethernet, power supply might have failed and your dicky might end up talking to 168 VDC (the peak value of the 120 VAC rms after the line rectifier and storage capacitor of the switching power supply. Or the isolation of the "wall-wart" transformer could fail. Or the Ethernet cable could short to building power, somewhere along its run. In either case your dicky is going to try to make the power meter, on your house, spin faster. Your dicky will retract itself, from this shocking situation, with such velocity it will pull into your body, turn inside out and stick out your ass, a condition that is not easily rectified.
Sometimes the nontechnical members of the board have not been informed of this possibility. Sometimes, if this happens to one of the members, they are too embarrassed to talk it about to the other members or they are dead, so this good to know information, has a tendency to propagate slowly, if not at all. So to restart the propagation I thought I would just mention it.
Remember A member is a terrible thing to waste!
