Hello ACPI developers,
The ACPI temperature on my Dell laptop (Intel Core i5-430M CPU) is strange.
You can not see the temperature unless you perform a "suspend to ram" operation.
This is what it shows if it is just booted (i.e. not performed any suspending).
$ cat /sys/class/thermal/thermal_zone0/temp
26800
$ cat /sys/class/thermal/thermal_zone1/temp
0
And they never change, until you perform a "suspend to ram"
(pm-suspend) operation.
After suspending and recovering, it turns to:
$ cat /sys/class/thermal/thermal_zone0/temp
26800
$ cat /sys/class/thermal/thermal_zone1/temp
51000
And the value of zone1 keep changes every several seconds, which I
think is the right temperature (51C).
But I don't know what's zone0 about.
Please fix it so that:
1 remove useless zone0, or tell what's that about.
2 make zone1 usable before suspending.
Thanks.
