Hello, I hope these questions are not way too stupid, but I've now been struggling for months, even the caretaker for linux at Siemens could not help. I'm at a Fujitsu-Siemens workstation Celsius w380 with ubuntu 18.04. Status is: sensors-detect finds: #----cut here---- # Chip drivers coretemp jc42 sch5627 #----cut here---- Those are in /etc/modules. sensors can read the values: $ sensors coretemp-isa-0000 Adapter: ISA adapter Core 0: +35.0°C (high = +83.0°C, crit = +99.0°C) Core 1: +32.0°C (high = +83.0°C, crit = +99.0°C) Core 2: +35.0°C (high = +83.0°C, crit = +99.0°C) Core 3: +33.0°C (high = +83.0°C, crit = +99.0°C) sch5627-isa-0580 Adapter: ISA adapter VCC: +3.36 V VTT: +1.12 V VBAT: +3.05 V VTR: +3.33 V in4: +1.13 V fan1: 1627 RPM (min = 0 RPM) fan2: FAULT (min = 0 RPM) fan3: FAULT (min = 0 RPM) fan4: FAULT (min = 0 RPM) temp1: +35.0°C (high = +36.0°C, crit = +191.0°C) temp2: +33.6°C (high = +36.0°C, crit = +191.0°C) temp3: +28.4°C (high = +36.0°C, crit = +191.0°C) temp4: FAULT (high = +36.0°C, crit = +191.0°C) temp5: FAULT (high = +36.0°C, crit = +191.0°C) temp6: +26.6°C (high = +36.0°C, crit = +191.0°C) temp7: FAULT (high = +36.0°C, crit = +191.0°C) temp8: FAULT (high = +36.0°C, crit = +191.0°C) Fans2-4 not functional is correct - I disconnected them because they are too noisy and not really necessary at my normal workload. Now with $ sudo pwmconfig I got the result: # pwmconfig revision 6243 (2014-03-20) /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed What can I do, hints are highly appreciated.
