What should I do if my Dell laptop won’t turn on and the screen is black?
If your Dell laptop isn’t turning on and the screen remains black, the first step is to ensure it’s receiving power. Check if the power adapter is plugged into both the laptop and a functional outlet. Look for any lights on the laptop that indicate power, such as the power LED.
