Method 7: Check Laptop Screen

In some cases, when you open the laptop, the indicator lights are still on but the screen remains black or is in sleep mode. Press the Caps Lock key; if the caps lock light on the laptop keyboard is still on, it indicates that the issue lies with the screen.

Next, check the screen brightness settings. If the screen brightness is reduced excessively, it will make the screen darker. Try increasing the screen brightness by pressing the dedicated key on the keyboard and check if the laptop screen has turned on.

Finally, try connecting an external monitor to your laptop. If the external monitor works, it means the issue only affects your laptop screen rather than the entire laptop graphics card or other hardware components.

In this case, the only option is to take your laptop to a warranty center or computer repair shop for repair.
