Question

why does my laptop have a black screen when i turn it on and when i turn it off and on it again it is starting normally?

Answer 1

Answer:

It's important to check that your computer and Windows are actually booting. To do this, press Windows key + Ctrl + Shift + B. This command actually restarts your graphics driver—which might itself fix the black screen—but also emits a beep. If you hear a beep, then Windows is responsive.
