There are a few relatively simple reasons you may experience a black screen. First, raise your laptop’s brightness to ensure this setting isn’t the problem. Most laptops have brightness keys to adjust it from the keyboard. According to HP, another issue may be a loose memory module. Ensure your laptop’s memory is inserted correctly and fully, then try again. HP also suggests trying to start the computer purely on AC power. To do this, remove the battery and plug the AC adapter into your laptop and a wall outlet. This helps verify that the battery or laptop’s charge level isn’t the reason you can’t see anything.
Perhaps you are experiencing a random PC black screen that can bother you a lot since there is not any error code or message giving you an idea where to start troubleshooting.
An unexpected black screen can happen on Asus, Lenovo, HP or Dell laptops in a number of scenarios in Windows 10, which may stem from hardware issues and logical faults – for example, a connection problem with your display, power supply, hard disk, internal memory, graphics card, virus attack, mistaken operations, software incompatibility and more.
