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,
