# To check that the status of your VGA devices, run this command:
lspci -vnnn | grep VGA
# Unplug laptop, click on the battery indicator and take note of
# estimated remaining time.
# Now run this script:
./test_off.sh
# If you see a "works!" message, it's found a method.
To check that the status of your VGA devices has changed,
run this command again and check for the differences:
lspci -vnnn | grep VGA
Click on the battery indicator after running the test.sh script,
it should show a difference of about an extra 1-3 hours battery life.
