How can I turn-off my laptop screen immediately if I want to?
Laptop: Lenovo Thinkpad
(Dual Boot) OS1: Linux Mint 17 OS2: Windows 8
I know there is power management, but it is not immediately. Need to set a time, and for Linux, the shortest is 5 minutes.
Is there any add-ons/extensions or software that can be downloaded so if I press a key, the screen will be turned off immediately?
