Screen is Black

My laptop is turned on, but I cannot see anything on the screen, regardless of any buttons I press.

Turn the Computer On

Ensure that the computer is powered on by holding down the on button and listening for the boot-up noise. You can also check to see if your computer is on by looking at the indicator lights on the base of the computer. If they are glowing the computer is on. Assuming that the device is on and the screen is still not functioning you may have other issues with the computer screen.

Brightness not High Enough

On your laptop, the F5 and F6 buttons change the brightness. To raise the brightness, hold the Fn key and the F7 key simultaneously until an acceptable brightness level is achieved. If this does not work, your buttons or hardware may be broken.

Monitor is in Sleep Mode

If pressing any button or toggling the trackpad mouse doesn’t immediately exit Sleep Mode, then you may be frozen, so hold the power button for about 20 seconds to shut the laptop off and then power back on. This should exit Sleep Mode, but if it restarts still in Sleep Mode, you may have an issue with the power or a glitch in the software.

Make Sure You are in Range of the Network

Determine how far away from your wireless connection you are. You can do so by clicking on the icon for wifi, and it will determine the signal strength of the connection. If the strength is low, you may be too far away. Try moving closer and see if the network will connect.
