    Does anybody (maybe jhonq) have an idea how to get control in linux (ubuntu) of the fans?
    There are no "fans" listed in the acpi part of Ubuntu.. :(

    Thank you!!

    Thank you for your reply!
    Do you now where to edit the decompiled DSDT table?
    Here is my one:
    Share-Online - dl/PCVFC36MJQC2

    If I could find the part where the fans get controlled I could tell the kernel to load this modified image and it should do the trick, but I am not sure where HP hide the settings :eek:

    Hello jhonq,
    do you plan support for probook 4540s ?
    I try TPFanControl in 4540s, but i always get pulsing fan in smart and manual mode, no matter the setting in the .ini.
    Thanks in advance !

    Fan allways on while on AC is off in the BIOS. Pulsing fan - the fan cycles for 5 seconds from off to 40-50% fan speed.
    i am trying Notebook fan controll at the moment with no success.

    Thanks for this amazing program!! I have one problem how ever, fan does not seem to spin in any other speed than 0 rpm or 3000 something rpm. So now when fan stops, temp start slowly rising, until it hits next temp treshold and immediatly starts the fan at high rpm. I have setted the threshold as in your picture, so i assume the fan should spin at slower speed allso...
