About laptops? Asus vivo book?

I just bought a new laptop at Media Markt. When turned on, the screen remains black even though I have charged it. You hear a noise and the lamp lights up. I connected it to my old screen and everything works fine there. Can someone help me?

At best do not even try to fix any problems there. Return the device and buy a new device. It's best to buy the new device online elsewhere, as Media Market laptops are always overpriced.

There are 2 possibilities the first one you have the display off you will find on your keyboard if you press the FN key and the top F8 key at the same time that does not let you give it a new one

Since the laptop is new, I would bring him back right away. Is just a DOA.
