There was some discussion about band gap in one of the other posts. Mine shows around 1.1 and when plotting it in Device Monitor, it moves between 1.0 and 1.1. I do notice that the ambient temperature seems very high to me. I'm in a 70 degree room at best, and its generally reading in the 100-110 range. Ron Ron, I don't know what Band Gap is. I do know that mine got hot to the touch when plugged into the computer. That made me nervous and I unplugged the battery and left it that way. John swapped it out for me and all has been good since (knock on wood). George,
