if you have ssh setup on the laptop you can ssh into the laptop remotely and/or ping it. If ping works or you can ssh into it it did not suspend. I have mine so that suspend is disabled when the lid is close but in place I have this script started up in rc.local: #!/bin/bash laststate=open while [ true ] ; do lidstate=`cat /proc/acpi/button/lid/LID0/state | awk '{print $2}'` if [ "${lidstate}" == "open" ] && [ "${laststate}" == "closed" ] ; then logger -s "at `date` lid was opened - full speed" /usr/local/bin/highspeed laststate=${lidstate} grep -i mhz /proc/cpuinfo | logger -s elif [ "${lidstate}" == "closed" ] && [ "${laststate}" == "open" ] ; then logger -s "at `date` lid was closed - low speed" /usr/local/bin/lowspeed laststate=${lidstate} grep -i mhz /proc/cpuinfo | logger -s fi sleep 10 done lowspeed does this: echo 400000 > /sys/devices/system/cpu/cpufreq/policy1/scaling_max_freq echo 400000 > /sys/devices/system/cpu/cpufreq/policy2/scaling_max_freq echo 400000 > /sys/devices/system/cpu/cpufreq/policy3/scaling_max_freq echo 400000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq And that keeps mine cool while still leaving it running. if I use it remotely via VNC I then run a script called highspeed that turns the max_freq to full My script you could modify to report the lid state every 10 seconds rather than going low power and log that to a file with the date/time.
