I have a laptop (Dell Latitude E6430) that I am using to record video files 24/7 at a remote site. I would like for the laptop LCD screen to turn off after a few minutes of keyboard/touchpad disuse to conserve power. Operating system is Windows 10.
Settings are, left click START, scroll to Windows System Control Panel, left click on power options, set "Turn off display" to "5 minutes" for both "On battery" and "Plugged in", and set "Put the computer to sleep" to "Never" for both battery and plugged in. When the laptop starts recording video, after 5 minutes the display turns off, however video recording is also stopped at this point. I assume that the system has been put to standby. Note that video is not playing to the screen during the recording process. However, when "Turn off display" is set to "Never" the laptop will record video for weeks without interruption as it should.
How can I turn off just the LCD after a few minutes without putting the entire system to sleep/standby?. Thanks in advance.
