This is a Linux driver for the IBM and Lenovo ThinkPad laptops. It
|
||||
supports various features of these laptops which are accessible
|

through the ACPI and ACPI EC framework, but not otherwise fully

This driver used to be named ibm-acpi until kernel 2.6.21 and release
|

0.13-20070314. It used to be in the drivers/acpi tree, but it was
|

moved to the drivers/misc tree and renamed to thinkpad-acpi for kernel
|
||||
2.6.22, and release 0.14.
