Summary: TZ Trip points are unreasonably high on N600c
Product: ACPI
Version: 2.5
Kernel Version: 2.6.28
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Fan
AssignedTo: acpi_power-...@kernel-bugs.osdl.org
ReportedBy: shopp...@tarek.org
Regression: Yes
I have basically never had heating issues with my Compaq Evo N600c until a
recent upgrade to Ubuntu's Jaunty 2.6.28. Now, the computer appears to overheat
and shut down regularly.
In doing some checking, these are the assigned trip points:
cat /proc/acpi/thermal_zone/TZ1/trip_points
critical (S5): 108 C
passive: 98 C: tc1=1 tc2=2 tsp=100 devices=C000
active[0]: 80 C: devices=C1E1
active[1]: 70 C: devices=C1E2
active[2]: 55 C: devices=C1E3
Which seem quite high. I cannot change the trip points manually, and have
played with the DSDT, though it is far above my ability.
I know this is an incomplete bug report, so maybe the next question is: What
else do I need to make it more complete?
