Why Is My Dell Laptop Screen Not Turning On. Laptop screen wont display after dropped works though. My laptop screen suddenly shows some small color boxes and goes black but laptop still on.
If you installed new hardware remove it and see if its not the one causing laptop not to turn on. Using one of these apps will start turning the monitor off but it will turn. Laptop screen wont turn on external monitor works perfectly.
When I restart screen shows nothing but Hard disk CPU fan are running normally.
Same applies for dual screen setup. To fix this issue you can disconnect the AC adapter and then remove the battery. Press and hold the D key on the keyboard and then press the power button and wait for the computer to start. Your power connection is loosenot connected.
