Hi,

I have a HP6735s Laptop, AMD Turion X2 and when running on high load for long periods it eventually overheats. I run a video encoder to make it work really hard and the processor goes to full 2.1GHZ and stays there even when temp crawls upwards of 95degC. Pause the video encoder and temp happily falls back.

I understand it is supposed to throttle the processor back on high temp.

rmmod powernow-k8, makes machine slow down (albeit gnome ondemand indicator still shows 2.1ghz), video encoder runs slowly, but processor runs coolest point 60degC. So this way its running too slow

Code:
cat /proc/acpi/processor/CPU0/throttling
state count:             8
active state:            T0
state available: T0 to T7
states:
   *T0:                  100%
    T1:                  87%
    T2:                  75%
    T3:                  62%
    T4:                  50%
    T5:                  37%
    T6:                  25%
    T7:                  12%
from lsmod

Code:

powernow_k8            24836  0

The only thing I can find wrong is

The machine has the latest BIOS software, but wondering if ACPI was broken. My battery on this machine under linux goes from 19 min and just switches off machine (hard off) no shutdown.


Any ideas greatly appreciated.
