I have a crude script that I run on machine startup that it puts my
cpus at the lowest speed when the lid is closed, but otherwise leaves
the machine on.
#!/bin/bash
laststate=open
while [ true ] ; do
lidstate=`cat /proc/acpi/button/lid/LID0/state | awk '{print $2}'`
if [ "${lidstate}" == "open" ] && [ "${laststate}" == "closed" ] ; then
echo "at `date` lid was opened"
/usr/local/bin/highspeed
laststate=${lidstate}
grep -i mhz /proc/cpuinfo
elif [ "${lidstate}" == "closed" ] && [ "${laststate}" == "open" ] ; then
echo "at `date` lid was closed"
/usr/local/bin/lowspeed
laststate=${lidstate}
grep -i mhz /proc/cpuinfo
fi
sleep 10
done
