lm-sensors sensor response ALARMING on min/max wrong


I think I set up my sensors3.conf file correctly (it took me a while to figure out to use sensors3.conf instead of sensors.conf in Kubuntu 9.04).

Unfortunately, it seems like it is alarming incorrectly for the negative voltages:
Clearly -11.84 is above the min of -13.18 and below the max of 10.82, but it says "ALARM". The same is true for the 5.08.

What's going on?

Code:
acpitz-virtual-0
Adapter: Virtual device
temp1:       +48.0°C  (crit = +100.0°C)

w83697hf-isa-0290
Adapter: ISA adapter
VCore:       +1.65 V  (min =  +1.60 V, max =  +1.70 V)
+3.3V:       +3.36 V  (min =  +3.14 V, max =  +3.47 V)
+5V:         +5.13 V  (min =  +4.76 V, max =  +5.24 V)
+12V:       +11.19 V  (min = +10.82 V, max = +13.19 V)
-12V:       -11.84 V  (min = -13.18 V, max = -10.82 V)   ALARM
-5V:         -5.08 V  (min =  -5.08 V, max =  -4.74 V)   ALARM
V5SB:        +5.46 V  (min =  +4.49 V, max =  +5.51 V)
VBat:        +3.25 V  (min =  +3.20 V, max =  +3.79 V)
fan1:        998 RPM  (min =  799 RPM, div = 8)
fan2:       2083 RPM  (min = 1318 RPM, div = 8)
temp1:       +28.0°C  (high = +40.0°C, hyst = +15.0°C)  sensor = thermistor
temp2:       +43.0°C  (high = +65.0°C, hyst = +46.0°C)  sensor = diode
beep_enable:enabled

One of the problems with lm_sensors is that it really needs to be dialed in to your specific motherboard. Print out your numbers and then compare them to the ones in your bios. You can then rewrite the equations to make the two sets of numbers match. Personally I just check that the numbers in the bios are all ok and then hang the printout on the wall were I can see it. As long as the numbers do not change significantly you have nothing to worry about.

lazlow, maybe I wasn't clear. The values ARE in between the set limits, properly. It seems that an absolute value seems to be being used.

We're looking at the two with the ALARM designation to the right of -12 V and -5 V.

It seems that whomever wrote the sensor code didn't know how negative numbers work (ie., that -10 is MORE than -13.

Hi,

Yes, there is a fault. You probably don't have the configuration setup to match your system (MB).

The presentation is alarming and presenting incorrect information. Make sure you have things matched properly for your Motherboard.

Personally I just ignored the -12V number as it now (by standard) a defunct number, but I have no idea why it is kick out an alarm (it should not be). It may be that there is a typo somewhere that simply dropped the minus sign.

On the -5.08 number I THINK at -5.08 it will kick of an alarm but at -5.07 it would not.

I changed the limits (reversing the negative limits) and now, no alarm.
