How do I fix my laptop I logged on and now there's a black screen but the cursors still there Also ctrl plus alt plus dlt works and I can log off and shut down through that But when I log on its black?

If your laptop has a black screen but the cursors still there and ctrl plus alt plus dlt works there may be a few issues. This could be a screen issue and bad LCD, loose or disconnected cable, or the backlight can be malfunctioning.
