bind shortcut key Fn+Q to this script. it need kernel module acpi_call to send command to acpi

tested for

• Lenovo IdeaPad 5 15
• Lenovo Xiaoxin Air 15

Hmm, this isn't working for me.

/proc/acpi/call: No such file or directory

Edit: Ah, I think I'm missing a package.

/proc/acpi/call need a kernel module acpi_call, you can search and install this in your package manager and reboot.

I did but I'm getting Error: AE_NOT_FOUND

the acpi command in script, is not for you device. what is your model, and if your device support Fn+Q on windows?

Yeah, I have a Legion 5 Pro 82JQ00UNMH. Fn+Q works in Windows. I just realized that Fn+Q also works in Manjaro, but it doesn't switch to high performance mode (red LED on power button). Only low and normal.

I can't help you, this script tested for IdadPad series

Ah. Thanks anyway!

It works for 21A2 ThinkBook 14 G3 ACL

How would you do that, also Fn+Q works but you just have to know what mode you are in. Tested on Ideapad 3 Gaming, debian 12

It works for Lenovo Ideapad 3 15

Would you suggest we add acpi to the user group of commands? As currently this app requires sudo password anytime we try to trigger/call in via the shortcut.
Or should we add this script to be executed without password for root?
