lm_sensors and Stdby

I just installed lm_sensors and they say this:

[root@gcomp george]# sensors
it87-isa-0290
Adapter: ISA adapter
VCore 1:   +1.74 V  (min =  +0.00 V, max =  +4.08 V)   
VCore 2:   +2.45 V  (min =  +0.00 V, max =  +4.08 V)   
+3.3V:     +3.26 V  (min =  +0.00 V, max =  +4.08 V)   
+5V:       +4.95 V  (min =  +0.00 V, max =  +6.85 V)   
+12V:     +12.86 V  (min =  +0.00 V, max = +16.32 V)   
-12V:     -20.36 V  (min = -27.36 V, max =  +3.93 V)   
-5V:       +2.99 V  (min = -13.64 V, max =  +4.03 V)   
Stdby:     +6.85 V  (min =  +0.00 V, max =  +6.85 V)   ALARM
VBat:      +2.03 V
fan1:     4560 RPM  (min =    0 RPM, div = 8)          
fan2:     4821 RPM  (min =    0 RPM, div = 8)          
M/B Temp:    +33°C  (low  =  +127°C, high =   +60°C)   sensor = thermistor   
CPU Temp:    +46°C  (low  =  +127°C, high =   +60°C)   sensor = thermistor   
Temp3:       -55°C  (low  =  +127°C, high =   +60°C)   sensor = thermistor

The stdby says alarm, because its maxed out, any one know what that means?

Re: lm_sensors and Stdby

I have no idea what "Stdby" means. It's probably some sensor that doesn't really give any useful information, but just to be sure go into your computer's BIOS and check the "PC health" menu (the one with the sensor read outs). Compare it to the values you posted: if it's not mentioned in the BIOS, it's probably not important.

You can set the high/low values and the alarm triggers in your /etc/sensors.conf file.

A train station is where a train stops.
On my desk I have a workstation.

Re: lm_sensors and Stdby

Well, that's the output for the standby line, it is quite similiar to the standby of a TV set, etc. and used to bring your PC back up from S1 (Power ON Suspend) or S2 (Standby) power states. Both power states usually don't work very well if at all under GNU/Linux. The ALARM is issued because +6.85V is much too much voltage. They are specified to carry +5.0V (+-10%). Probably your PSU is not quite up to snuff but as FUBAR pointed out, if you BIOS ignores this, you can, too.

If this is an important production machine, replace the PSU ASAP.
