runtah

For the last 2/3 days Im on #! (CrunchBang Linux). The only real complain I have had is "Battery!". Fortunately enough, I found a script on the Crunchbang Forums here [http://crunchbanglinux.org/forums/viewtopic.php?id=11954] that solves the issue.
CAUTION: Please check if the files that are beings used by the script, do exist.
Copy the script and put it into /etc/pm/power.d/powersave and make it executable using

chmod +x /etc/pm/power.d/powersave

The script is:

#!/bin/sh
# A script to enable laptop power saving features for #! & Debian GNU+linux.
