The ThinkLight is a little LED light integrated into the top edge of the display frame in the A, R, T and X ThinkPad models. It illuminates the ThinkPad's keyboard so that one can type in the dark without using an external light source. The ThinkLight can be controlled via the Fn-PageUp key combination or via ACPI on some of the newer models. Note that the ThinkLight is not available on the G series ThinkPads. |
Linux Support
Controlling the ThinkLight with the keyboard works on all systems since it relies on the BIOS exclusively. Just press FnPageUp to toggle its state between on and off.
Support for controlling the light with ACPI is provided by ibm-acpi. After installing it, a simple
# echo on > /proc/acpi/ibm/light
switches it on and a
# echo off > /proc/acpi/ibm/light
switches it off again.
This allows one to control the light in scripts. Unfortunately, no known ThinkPad comes with a light sensor (yet). ;)
