How to turn off laptop display with one click

1- Screen off - simple name

One of the best tools that I personally like,the user can turn off the laptop screen and the desktop computer and save energy. This tool is especially important for laptops because there is no button for locking the screen. The tool is very simple, portable which does not need to be installed. Clicking it will work with you immediately and the computer screen will be turned off. When you move the mouse, the screen will return to work again.[download]

2-  Turn Off LCD 

Simply a little executable that turns off the LCD of your laptop or the monitor of your PC.

Turn Off LCD keeps your laptop LCD or PC monitor sleeping. To wake up your monitor, simply wiggle the mouse or type any key on the keyboard.

It also lock the computer when you turn off the screen.

The program doesn't require installation, simply run the executable..[download] Or [download]
