The warning level is set to -1. So, there should be no warning. The temperature level for shutting down is set to 99 degrees. This value is never reached and the machine also never shuts down. > > My laptop was shutting down from overtemperature until I realized that > I had placed it next to something that was blocking the fan vent. > I placed the machine the same as it runs for at least 3 months now. As I have said before, the temperature shown are the same as before. Just the warning comes up when the machine is loaded. Erich
