Message-ID: <200303100404.14947.pezed@pezed.net> (raw)
I've been trying for about a week now to get acpi working properly on this
machine (using 2.4.21-pre5 and the latest acpi patch) but im just not having
much luck. The annoying problem is the fan. The fan comes on as it should,
but then it will never go off again. The fan is "detected" and shows up under
/proc/acpi/fan/FAN/ and under /proc/acpi/power_resource/PFAN/. Both of these
directories have a "state" file which show:
mark@lappy /proc/acpi/fan/FAN]$ cat state
status: off
[mark@lappy /proc/acpi/power_resource/PFAN]$ cat state
state: off
system level: S0
order: 0
reference count: 0
"echo 0 > /proc/acpi/fan/FAN/state" shows the following:
acpi_power-0363 [50] acpi_power_transition : Error transitioning device [FAN]
to D0
acpi_bus-0496 [49] acpi_bus_set_power : Error transitioning device [FAN] to
D0
"echo 1 > /proc/acpi/fan/FAN/state" shows:
acpi_bus-0447 [49] acpi_bus_set_power : Device does not support D1
/proc/acpi/power_resouce/PFAN isnt writable.
cat /proc/acpi/event will properly show when the lid switch or power button is
pressed.
battery info doesnt appear to be read correctly as it shows a battery even
when i remove the battery. (doesnt bother me)
thermal info appears to be read correctly (temp goes up and down with system
load).
the fan problem is the only thing that is really bothering me (the fan is
loud!!). i've tried to create my own dsdt file with no luck. in the stock
dsdt file Device(FAN) appears to be an alias to PowerResource PFAN.
i've searched the net over and cant seem to find any info on this laptop and
acpi. :(
any help or tips would be greatly appreciated!
thanks!
