It may not make much difference for your old sensors-detect and for you, but it may make for us especially if you use the latest version of sensors-detect: http://www.lm-sensors.org/browser/lm-sensors/trunk/prog/detect/sensors-detect?format=txt So please give it a try and report the full output. Maybe it won't find anything, maybe you just don't have sensors on that system, but at least we'll be sure. Is there any hardware monitoring information reported by the BIOS? -- Jean Delvare
