Measure, explain and minimize a computer's electrical power consumption

Run this command as root to get enough stats. It works on AMD and Intel machines, including desktops. If ran on a laptop it'll give you suggestions on extending your battery life. You'll need to install PowerTOP if you don't have, via 'apt-get install powertop', etc. To grep the output use: sudo powertop -d | grep ... The many command suggestions PowerTOP gives you alone will increase your command-line fu! Show Sample Output

sudo powertop

Check whether laptop is running on battery or cable

This prints "Charging" or "Discharging". Obviously, this will indicate the status of the AC adapter. The awk part could be from 1-6. I removed the comma because it is useless when only looking at one element of the output array. See acpi(1) for more info.
