[gentoo-user] lm_sensors laptop issues

[James]

Hello,

I've been trying to get lm_sensors to work using:

lspci -v
lshw
discover
sensors-detect  
modprobe i2c-dev  and
'i2cdetect -l' returns:
i2c-0   unknown  SiS96x SMBus adapter at 0x8100  Algorithm unavailable

but building a 2.6.15-gentoo-r5 kernel, in the menu I see:
<M> SiS 96x                                                  
<M> I2C/SMBus Test Stub  

It's a Clevo 'D470W' portable. Googling, I can find lots of 
mobo's listed but no laptops?

lm_sensors and sensord are both installed and running.

Ideas?


James

What modules did this actually load?  (Use -v.  Or do lsmod now.)

Doesn't "Test Stub" mean that it doesn't really do anything?  Read 
the help, and probably say No.

OK I eliminated that from the 2.6.15-gentoo-r5 kernel, but, it makes no
difference:

sensors -s
No sensors found!



/etc/conf.d/lm_sensors reveals:
# Load modules at startup
LOADMODULES=yes

# Initialize sensors at startup
INITSENSORS=yes

MODULE_0=i2c-sis96x
MODULE_1=eeprom


I just don't get it.....?

There's no sensor module loaded.  sensor-detect will have told you 
what chip it has found, select it in "Hardware Monitoring support" 
(two down from I2C support), and add it to the load list.

Well it's still not working the laptop, but I got it working
on Asus A7V8X-X mobo. I'll go back to the laptop later.....

fan3:        0 RPM  (min = 3000 RPM, div = 2)          ALARM
M/B Temp:    +49 C  (low  =   +15 C, high =   +40 C)   sensor = thermistor
CPU Temp:    +44 C  (low  =   +15 C, high =   +45 C)   sensor = thermistor
Temp3:        +2 C  (low  =   +15 C, high =   +45 C)   sensor = disabled



so should I be worried about the mobo temperature? Add another cool fan?



It also looks like the power supply is not regulating very well?
Can I believe these voltages?

Any other suggestions?

may be wrong divider


> +3.3V:     +6.40 V  (min =  +3.14 V, max =  +3.46 V)   ALARM
definetly wrong divider, halfed, 3.2V, which is acceptable.

> +5V:       +4.81 V  (min =  +4.76 V, max =  +5.24 V)
acceptable

> +12V:     +12.86 V  (min = +11.39 V, max = +12.61 V)   ALARM
maybe this or that ;)

ok

not read
> fan1:     4245 RPM  (min =    0 RPM, div = 2)
a little bit high

I suspect wrong divider.

only if you have problems with your systems stability.

no
but you can never believe the voltages.
The absolut numbers are irrelevant.
What is important: are there any fluctuations? Does the voltages change under 
load? 
if yes, a new PSU may be the solution

Do you know of any sites containing listings of how LM_sensors
works on laptops?  I could find several for mobos but, none
specific to laptops....


Thanks for all of your help. Next time it's a Tyan mobo for me.

be carefull with tyan! Tyan mobos are very picky about the PSU. Don't buy an 
Antec to use it with Tyan boards.

And for your question: no, I do not. I were never interessted in laptops ;) 
If it weights less than 10kg, it is not a computer ;)
