Ibm-acpi

ibm-acpi - IBM ThinkPad ACPI Extras Driver

This is a Linux ACPI driver for the IBM ThinkPad laptops written by Borislav Deianov. It aims to support various features of these laptops which are accessible through the ACPI framework but not otherwise supported by the generic Linux ACPI drivers. As a kernel module, ibm-acpi works as a bridge to deliver information about certain hardware events like key presses or control the state of certain hardware features by software.
