ACPI action script optimized for R51
From ThinkWiki
This is a complete acpid and tpb script optimized for a Thinkpad. It is intended to be used by advanced users (as, for example, it gives control over the CPU frequency to the user instead of running a frequency daemon)
It's features include
- screen blanking / screensaver
- hibernate / suspend
- (un)load wlan driver
- enable/disable lcd/vga
- change CPU frequency
- ... See the beginning lines of the script for more detailled information.
