Is anyone familiar with a HP 8530 laptop?
In general, or for this model or HP family in particular, how does
one control the fan speed?
To date:
[root@localhost ~]# cat /proc/acpi/fan/FANG/state
status: off
[root@localhost ~]# fancontrol status
Loading configuration from /etc/fancontrol ...
Error: Can't read configuration file
I definitely can feel the fan running. I have removed and replaced
the keyboard to get access to the fan so that I could use compressed
dusting gas to remove any dust accumulations (a relatively simple
procedure for this particular model), and have observed some
reduction in running temperature as reported by gkrellm. Currently,
CPUZ is 63 C with a CPU composite load average of approximately 40
percent.
Is there an OS environment (currently, SL 6x) or, for those familiar
with these HP machines, a BIOS, mechanism for forcing the fan to
maximum? How does one "fix" /etc/fancontrol, or is this not
feasible/useful?

[root@localhost ~]# pwmconfig
# pwmconfig revision 5630 (2009-01-29)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
end output.
Thus, your suggestion fails (actually, pwmconfig was one of the first
things I tried). There may be a different version/switch/program that
handles non-pwm sensor modules or there may be such hardware/firmware
modules on this particular computer but these have not been interfaced
to / activated by the OS environment. How does one discover if pwm
hardware/firmware is present?
NB: When I first joined this list, I was railed against for
replying/posting to the front of an email/list thread/message (a
practice common with other email correspondence); thus, I am replying to
the end/bottom.
