Laptop does not start anymore

Hi. My mother's laptop does not start anymore.

What I can say about the device is that it is an ASUS R558U. Since 2 years old.

She says she looked at Firefox emails and clicked on X to quit Firefox suddenly her laptop went out and since then he can't make on.

He turns black shows the ASUS sign… Is completely black and then such a gray-black background and the curser but can be moved… But more does not happen.

We let him stand half a day in the hope that he needs more time but nothing. But then he can't turn off then we take him from the plug bar and leave the battery is empty so he goes out.

I do not know what to do, why is it and what can I do?

I'm only here today and have to go back home.

Power button for more than 5 seconds. Press and hold. Then he goes out.

After the restart, then go directly to the BIOS to see if that still works.

No, not! I know how laptops work xD

Go to bios when starting.

he hopes something else.

Restart Win.

Kaput does not look the screen.

I'm not 100% sure, but notebooks with built-in battery have a reset switch. Such a small hole in the cover where you can reset it with a "needle".

Bios goes

It showed a short welcome to there he went back to black. Then I went to Bios.hab it closed again with ESC and then came back again… Then started the laptop… No idea what that is?

Just wanted to put photos on USB and when I opened images, the folder has closed again

I recommend backing up the data to a hard drive, and then reinstalling windows

Yes, I think that's a good idea
