I hope nothing happens to her, but it would be a different kind of Dell commercial, That kid Steven walks into the bathroom, startles the naked sister in the tub with Inspirion 4300 she knocks it into the water, and Steven says" Dudette you getting Electrocuted"
WOW ! Pretty esoteric analysis of power supplies, GFCI’s etc. etc. Did anyone suggest to check Charles Dalziels research work on electrocutions in human adults ?
May I respectfully suggest, that you suggest that she find something else to do in the tub … If that dosen’t work help her maximize the computer time. Build her a platform for the car. Something that sits on the dash perhaps in front of the windshield then she can get more computer time in while driving.
