How to Fix an HP Laptop Screen When It Goes Dark

If the screen on your HP laptop has gone dark for no particular reason, you may be at a loss as to what exactly is going on with your computer. Most likely the problem lies with the screen inverter. This is the small rectangular circuit board that provides power to your screen so it can light up. Without a functional inverter you won't be seeing a whole lot on your laptop screen. The good news is that it's possible to fix your screen and inverter on your own.

Turn off your HP laptop and remove the power cable if it's connected.

Flip the LCD screen to its open position and use the tip of your Phillips screwdriver to pop any rubber screw covers off of the plastic bezel (the frame surrounding the screen). The amount of screws vary from laptop to laptop, but they are usually located on the top and bottom sides of the bezel.

Use your Phillips screwdriver to remove the screws on the bezel and set them aside.

Use your fingers to work your way around the bezel at the corners and gently pry it away from the screen. The green inverter board will now be visible just below the screen.

Use your fingers to make sure the two cables plugged in at either side of the inverter board are not loose. Press them firmly into the sockets to make sure they are connected. Replace your screen bezel and screws. Your inverter board will now be fixed.
