what causes laptop screen to go black
Computer Crash. One of the most complicated reasons the screen goes black is a crash. This could occur for a variety of reasons, and is often difficult to fix. You will have to take the machine to a computer repair shop, and they will open up the laptop there to find the cause.
At times a simple loose connection may cause your screen to black out. The data ribbons that connect the hard drive to the screen may get loose, or wear out over time. A simple way to test this would be to attach your laptop to an external screen.
