=== 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.

Some of these features are available only when the module is loaded with the <tt>experimental=1</tt> option. To enable it, add the following to {{path|/etc/modprobe.conf}} (or your distribution's equivalent):
+
options ibm_acpi experimental=1

+
=== Project Homepage / Availability ===
+
* Homepage: http://ibm-acpi.sourceforge.net/
+
* ibm-acpi is included with the Linux kernel since 2.6.10.
+
 
+
=== Status ===
+
In development, usable, maintainership is being transferred to a new maintainer.  Patches should go to the ibm-acpi-devel mailing list.
+
 
+
Even if you have disabled the BIOS setting for automatically dimming at battery power, after using the brightness switch of ibm-acpi, the auto-dimming behavior is enabled. So, if you need a bright display even on battery power, you should not set any brightness via /proc/acpi/ibm/brightness.
