    Solution 2 requires a patched `thinkpad_acpi` kernel module, and is only recommended for advanced users who know what they are doing. This is because the patch is not included by the thinkpad_acpi developers by default, ([See this discussion for more details](http://comments.gmane.org/gmane.linux.drivers.platform.x86.devel/1962)).
