The lcd of my Dell inspiron 3521 laptop is dead. I can't see anything on it at all. I need to go into the is of the laptop using an external desktop screen but having trouble doing so. Any help please.
Once you have the external monitor plugged into the laptop you have to go into the Display Options and change the display to the external monitor from the lcd. Unfortunately, if you cannot see anything on the lcd screen you cannot change the settings. You will need to replace the lcd screen.
