i am using linux mint 17 cinnamon , well somehow i have some problemes in my laptop charger , i like my panel to be hidden so it's hard to watch if the charger is connected or not .

is there any way to configure or create a script or something to notify me if my charger is disconnected ?

1 Answer 1


Run this script at background:

while :;do
    (( $(</sys/class/power_supply/ADP0/online) )) || notify-send offline
    sleep 1
  • sleep 1 will make my laptop in sleep mode ? then how to save this script to be rune automatically ?
