[lm-sensors] Dell Latitude D610 and 2.6.16

[Andrew Pollock]

Hey,

I just thought I'd try out lm-sensors on my Dell D610 with what's in 2.6.16,
and sensors-detect decided that i2c-i801 and eeprom should be loaded, but
the sensors command fails, and there's nothing in /sys/class/hwmon (where I
presume from stracing sensors there is supposed to be something).

Should this work with this hardware?

regards

Andrew

The result you have is consistent with the drivers you loaded (which in
turn sound OK for your hardware, I have a Dell Latitude D600 and I use
the same drivers.) The sensors program and libsensors library were
modified in lm_sensors 2.10.0 not to show non-sensors devices anymore
(at least for 2.6 kernels.) EEPROMs are not sensors so it didn't belong
there in the first place.

You can obtain information from your EEPROMs by using the
decode-dimms.pl script from the lm_sensors package instead.

FWIW, the D600 is a vastly different beast to the D610. I made that mistake
when I bought it.

So are you saying that given the drivers I've loaded, there's nothing to
report on?

Ah, didn't know that. I stupidly assumed that nearby numbering meant
nearby design.

Yes, that's what I think, and said.

Your best chance for hardware monitoring on this laptop is ACPI
(fan, ec and thermal). Load all available acpi modules and see
in /proc/acpi/{embedded_controller,fan,thermal_zone} if there's any
interesting data to be found.

On my D600, embedded_controller and fan are empty directories, but
thermal_zone has some interesting files. I can get the system
temperature, a status flag and a critical temperature limit (which I can
also set). That's a bit cheap and inconvenient compared to what
lm_sensors can offer, but that's much better than nothing at all.

There's some documentation available about acpi/thermal_zone here:
http://acpi.sourceforge.net/documentation/thermal.html

Hope that helps,

Yup, I see the same. 66 degrees seems a bit hot to me.

Thanks.

It's better than a poke in the eye.

Indeed. My D600 has only 35 degrees C (although it feels much more) and
my other laptop 49 degrees C. I wouldn't want a laptop at 66 degrees C
when idle. Is the fan spinning?
