You often need to turn off your laptop’s LCD display to save on battery power, but don’t want it to go on sleep. This used to be fairly easy on a Windows PC but I had a hard time figuring out how to do this on a Mac.
Just try this useful but not very commonly known keyboard shortcut:
CTRL + SHIFT + EJECT
I bet you didn’t know this
u can decrease the brightness to 0 as well
Yeah, but that still doesn’t turn off the display. It only turns off the LED illumination!
