Hello, List!
I'm having a problem with HP's Omnibook XE4500.
I cannot control the fan using its /proc/acpi interface. There is a fan
entry and I can try to set some options, however - they are not set
effectively (seems like Linux isn't in control of the fan). I'd like to
set the trip_points to some values so that the fan doesn't come on so
often. Any hints on where to start? Or it is not possible on Linux anyway?
There is a fan.exe on the diagnostic partition which switches the fan on
and then off for diagnose purposes, so it _should_ be possible to
control the fan by software.
Thanks for any information!
Thomas
