My laptop does not boot \ the screen remains black

Introduction

Black screen issues can be caused by various circumstances such as an aborted flash operation during a BIOS update, corrupted BIOS memory chip, an incompatible or third-party modified BIOS ROM being flashed or various hardware root causes. Such an issue might not be permanent - it could also be caused by system memory (DDR4/DDR5) not being plugged in correctly or running at incorrect settings.

Rule of thumb: if the laptop works correctly, you should be able to access the BIOS setup with the F2 hotkey. To access the BIOS setup, you only need a CPU, compatible memory (RAM), and the laptop's internal monitor. A working Windows installation or indeed any SSD is not necessary.
