Red Hat Bugzilla – Bug 202749
/etc/sensors.conf uses wrong voltage limits on Asus K7M motherboard, resulting in beeping during bootup
Last modified: 2015-03-04 20:17:31 EST
Description of problem:
The /etc/sensors.conf file uses wrong voltage limits for the Asus K7M
motherboard. This results in beeping as soon as 'sensors -s' is executed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start lm_sensors service
System starts beeping due to wrong voltage limit settings in sensors.conf
Correct voltage limits used, no ALARM goes off.
This issue became apparent only after kernel-2.6.16-1.2133_FC5, since only then
the beep function started working.
In the following section:
chip "w83782d-*" "w83627hf-*"
I changed the following lines:
label in1 "VCache"
set in1_min 3.3*0.95
set in1_max 3.3*1.05
Output of 'sensors' now is:
Adapter: ISA adapter
VCore 1: +1.65 V (min = +1.54 V, max = +1.70 V) (beep)
VCache: +3.36 V (min = +3.14 V, max = +3.46 V) (beep)
+3.3V: +3.36 V (min = +3.14 V, max = +3.46 V) (beep)
+5V: +5.08 V (min = +4.73 V, max = +5.24 V) (beep)
+12V: +11.80 V (min = +10.82 V, max = +13.19 V) (beep)
-12V: -12.20 V (min = -13.18 V, max = -10.88 V) (beep)
-5V: -5.00 V (min = -5.25 V, max = -4.75 V) (beep)
V5SB: +5.03 V (min = +4.73 V, max = +5.24 V)
VBat: +3.26 V (min = +2.40 V, max = +3.60 V)

temp2: -48.0Â°C (high = +80Â°C, hyst = +75Â°C) sensor = thermistor
temp3: -48.0Â°C (high = +80Â°C, hyst = +3Â°C) sensor = thermistor
vid: +1.625 V (VRM Version 9.0)

This is not a bug, lm_sensors is not a plug and play package and might never be.
In order for it todo anything you must manually run sensors-detects, you are
also expected to manually edit your /etc/sensors.conf after this to match your
