I have a Dell Inspiron laptop. When I hit the power on button it comes on but all I get is a white screen with a funny-shaped black shape. I have left it plugged in for 2 hours and nothing happens.

Hello Gary Clark,

Can you provide me with the Model of the laptop, this will help in troubleshooting.

You may also want to try booting into the Dell pre-boot diagnostics tool, this might let us know why your computer is not booting up.

Hello Gary,

I found something to try in the Dell support forums.

Try holding the power button for about 20-25 seconds with the charger unplugged. Keep holding even when it turns on. If it’s out of warranty you can also try this with the battery disconnected.

Another trick you can do is fully turn off the laptop, then hold down the Fn key (in the bottom left of your keyboard) and then turn the laptop on while you keep holding down Fn. That’s supposed to bring up pre-boot diagnostics.

Neither of those worked.

All I can get is a white screen with a strange symbol. It is a large black dot with a long black line going out to each side and one to the top

Hello Gary,

Try repeatedly pressing the F12 key on your keyboard as soon as it powers on; if you get the boot selection menu, try going into diagnostics from there.

I found this info Here on Dell’s support page for your model laptop.
