From 65bd97c6360a0e5190e393b84bc6b2d2029439a3 Mon Sep 17 00:00:00 2001 From: Stefan Ott Date: Wed, 22 Apr 2020 23:20:03 +0200 Subject: mb/lenovo/t520: Add support for ThinkLight With this patch, the ThinkLight on the ThinkPad T520 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 T520 to test this.
