Hello @ezrazazeldev ,

I had a look at your firmware. Maybe your notebook fan can be controlled via ACPI methods.

To control your fan, you need to install the acpi_call kernel module:

For Debian / Ubuntu: sudo apt install acpi-call
For Arch Linux: sudo pacman -S acpi_call
For Fedora / OpenSuse: The acpi_call module has to be installed manually

Important:

Before following these instructions, make sure that your notebook is in a state where you can turn it off without any data loss. So close applications, save documents etc.

The notebook's fans are probably controlled via the FANG/FANW methods.

Please tell me which (if any) solution worked for you:

Solution 1:

• Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANW' 33026 0x0 -- this should turn off your fan
• Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANW' 33026 0xFF -- this should set the fan to maximum speed
  If the fan speed changes to maximum, wait for 5 seconds. I need to know whether the fan gets reset to normal speed after 5 seconds.

If this solution worked for you, then please reboot your notebook to restore normal embedded controller fan control.

Solution 2:

• Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANG' 33030 -- write down the value that is printed out
• Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANW' 33030 0xFF -- this should turn on manual control for your fan
• Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANW' 33026 0x0 -- this should turn off your fan
• Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANW' 33026 0xFF -- this should set the fan to maximum speed
• If you could change the fan speed speed, run:
  • Run sudo ec_probe acpi_call '\_SB.PC00.LPCB.EC0.FANW' 33030 VALUE -- replace VALUE with the output from the first command (for example 0x08)
    Please tell me whether the last command did reset the fan and with which VALUE you called it.

If this solution worked for you, then please reboot your notebook, to restore normal embedded controller fan control.

Regards,

Benjamin

Benjamin,

Thank you for the in-depth step-by-step. Please bear with me, I use CachyOS and thus their customized kernel, so I need to switch over to the mainline kernel as acpi_call depends on it. I'll reply once again after setting that up and testing both provided solutions.

[ezrazazeldev]

OK, so it seems acpi_call doesn't work like a command, and I'm not sure how to use it since the documentation is a bit confusing to me.
