HOw long have you had your Pleo? Is it still under warranty? Do you have another clock battery, perhaps trying a new clock battery as they do wear out, even though they can last for more than a year, I have had to replace one battery in a pleo twice for some reason. Did you run any other programs recently before your pleo stopped running?
Your pleo sounds "similar" to a problem I have been having with Cammie Sue. She completely stopped running and her battery light on the stomach stayed green, but no sound or noise at all. Have you by any chance run either Stats RB or Probe Rb on your Pleo lately? I am sure Mike or others can help even without aid of a computer. Let us know any other vital information. RWM
