From 4e448fb79b426c6f7bdd0aa6fe2c4d0394e7de7c Mon Sep 17 00:00:00 2001 From: Stefan Ott Date: Wed, 22 Apr 2020 23:20:03 +0200 Subject: [PATCH] mb/lenovo/t430: Add support for ThinkLight With this patch, the ThinkLight on the ThinkPad T430 can be controlled through the OS. The same change was done for the ThinkPad X200 in b45912f4: mb/lenovo/x200: Add support for ThinkLight After applying this patch, the light can be controlled like this: echo on >/proc/acpi/ibm/light echo off >/proc/acpi/ibm/light Or through sysfs at /sys/class/leds/tpacpi::thinklight Unfortunately I do not own a T430 to test this.
