Touchpad lock button not working

This post is pretty much goes like this one: https://bbs.archlinux.org/viewtopic.php?id=142108

My HP laptop has a small button in the corner which disables the touchpad if I press it twice. Also, it has a LED indicator that turns orange when the touchpad is disabled. So far it doesn't seem to work in any Linux distro (arch, fedora, ubuntu, etc...) with the default drivers.

I already tried installing xf86-input-synaptics to no avail. xev doesn't show anything relevant if I press the lock button. It recognizes it as a normal touchpad click so I guess the lock button isn't even recognized by the driver.
Here's some output:

$ pacman -Q | grep xf86-input

xf86-input-libinput 0.26.0-1
xf86-input-synaptics-led 1.9.0-1

$ ls /sys/class/leds  // already tried echo'ing 1 to the brightness file inside psmouse::synaptics and nothing happens

 hp::hddprotect  input0::capslock  input0::numlock  input0::scrolllock  psmouse::synaptics

$ synclient -l | grep LED // setting LEDStatus to 1 doesn't do anything although it writes 255 to the brightness file

    LEDStatus               = 1
    LEDDoubleTap            = 1 

$ dmesg | grep synaptic
