Backtrack 5 - fancontrol problem in my laptop nx6115 HP

[nitroglico]

Hi. I installed this Backtrack version 5 (revolution) in HD from my laptop, HP model nx6115

Before, I had BT4 and I never got this problem.. I have Windows in another partition and this problem dont happen.

My laptop is getting hot, to a level where it simply freezes.. Look at sensor output while i am posting it..

acpitz-virtual-0
Adapter: Virtual device
temp1: +56.0°C (crit = +94.8°C)
temp2: +50.0°C (crit = +100.0°C)
temp3: +24.8°C (crit = +100.0°C)
temp4: +0.0°C (crit = +110.0°C)

k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +59.0°C

max1617-i2c-6-4c
Adapter: SMBus PIIX4 adapter at 8200
temp1: +50.0°C (low = -128.0°C, high = +90.0°C)
temp2: +67.0°C (low = -128.0°C, high = +69.0°C)

I tried everything to get fan working, but i am unable,

what should I do to get it working..


*** This problem seens to be affecting many people that installed backtrack 5, just try to google it:

Probably an acpi driver issue. Check the Ubuntu forums, there's probably a fix.

Looking there, I found it.. that is the same laptop as me and same problem, but the solution wasnt found yet

Hi folks.
I have an issue concerning temperature control in a HP NX6115 laptop.
It is a Turion 64 ML-32.
The fan is controlled using a sensor that is not the core temperature sensor. The core sensor communicates with the OS using driver max1617-i2c-0-4c, wich was detected using lm-sensors.
If I run sensors I got:
Code:

acpitz-virtual-0
Adapter: Virtual device
temp1: +37.0°C (crit = +94.8°C)
temp2: +42.0°C (crit = +100.0°C)
temp3: +30.7°C (crit = +100.0°C)
temp4: +50.0°C (crit = +110.0°C)

k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +31.0°C

max1617-i2c-0-4c
Adapter: SMBus PIIX4 adapter at 8200
Board Temp: +42.0°C (low = -128.0°C, high = +90.0°C)
CPU Temp: +49.0°C (low = -128.0°C, high = +70.0°C)

Running cat /proc/acpi/thermal_zone/*/trip_points
Code:

critical (S5): 95 C
passive: 88 C: tc1=1 tc2=2 tsp=100 devices=C000
active[0]: 80 C: devices=C256
active[1]: 75 C: devices=C257

critical (S5): 110 C
passive: 110 C: tc1=1 tc2=2 tsp=300 devices=C000

Running acpi -tc
Code:

Battery 0: Full, 99%
Thermal 0: ok, 50.0 degrees C
Thermal 1: ok, 30.1 degrees C
Thermal 2: ok, 41.0 degrees C
Thermal 3: ok, 36.0 degrees C
Cooling 0: Processor 0 of 10
Cooling 1: Fan 0 of 1
Cooling 2: Fan 0 of 1
Cooling 3: Fan 0 of 1
Cooling 4: Fan 0 of 1

There is only 1 cooler in the system and it is controlled using 4 steps (Cooling 1-4).
For temp1 > 58°C, cooling 1 turns on. For temp1 > 65, cooling 2 turns on and so them go. But when temp1 ~ 65°C, CPU Temp ~ 77°C and I got only the second fan stage turned on.
I would like to know if is there a way to set acpi to use the right sensor to control fan speed, so my system runs cooler. I don't care about noise or power consumption (this is the next step).
I'm new to Linux and maybe this question is stupid, but I could not find anything like this in the forum.
Thanks in advance.

It looks like temp1 is always 12°C below CPU Temp. Is there a way to change that?
When CPU Temp goes above 80°C, the system freezes.

I am not finding a fix there, Barry, but it seems this problem is related to the kernel support to my HP nx6115 laptop..

Ok, Here is how you can fix that problem; While the kernel patch isnt released, you can work
with no problem if you use the option: acpi.power_nocheck=1

GRUB_CMDLINE_LINUX_DEFAULT="text vga=791 acpi.power_nocheck=1"

at least, I leaved it all night running a password cracking program, with no problem, computer freezes no more..
