/proc/acpi/ibm, I see multiple devices provided by kernel module
x230:/proc/acpi/ibm$ ls beep bluetooth cmos driver fan hotkey kbdlight led light video volume
Is there anyway though that I can change the status of the ThinkLight? If I
echo 0 on > light, I can address and turn on the power light, but the rest of those
[1-15] seem to register as invalid. What controls the Thinklight?
$ echo heartbeat | sudo tee /sys/class/leds/tpacpi::thinklight/trigger tee: '/sys/class/leds/tpacpi::thinklight/trigger': Invalid argument
Interestingly enough this seems to follow this post, where the light can be turned off with,
echo 0 > /sys/class/leds/tpacpi\:\:thinklight/brightness
but not turned on again
I'm using Debian Testing with Kernel 4.19, on a Lenovo x230.
