    Default Backtrack 5 - fancontrol problem in my laptop nx6115 HP

    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: +56.0C (crit = +94.8C)
    temp2: +50.0C (crit = +100.0C)
    temp3: +24.8C (crit = +100.0C)
    temp4: +0.0C (crit = +110.0C)

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

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

    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.

    Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69

    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: +37.0C (crit = +94.8C)
    temp2: +42.0C (crit = +100.0C)
    temp3: +30.7C (crit = +100.0C)
    temp4: +50.0C (crit = +110.0C)

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

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

    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
    active[2]: 65 C: devices=C258
    active[3]: 58 C: devices=C259
    critical (S5): 100 C
    passive: 90 C: tc1=1 tc2=2 tsp=300 devices=C000
    critical (S5): 100 C
    passive: 60 C: tc1=1 tc2=2 tsp=300 devices=C000
    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 > 58C, cooling 1 turns on. For temp1 > 65, cooling 2 turns on and so them go. But when temp1 ~ 65C, CPU Temp ~ 77C 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 12C below CPU Temp. Is there a way to change that?
    When CPU Temp goes above 80C, 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..
