yes it is over charging of the batteries. Laerdal contacted us and told us that they are not supposed to be plugged in 24/7 while running scenarios. They are made to run off the batteries, then when the batteries get low, that is when you plug them in until they recharge. I haven't yet tried the cooling pads yet, but I was either going to take the skin off the man, then place them on the computer while he laying down, then replace the skin; so the pad is right up against the computer. Or just place the pads between the manikin and the bed, and see if that cools him down at all. It works on any other computer, so I don't see why it wouldn't at minimum help out in this case.
