Hi,

What is the model number of the laptop?

Try connecting an external monitor to the laptop and check if there is a display on it.

Even a TV can be used as an external monitor if both it and the laptop have HDMI ports and you have the appropriate cable to connect the two together.

Remember to operate the appropriate laptop function key to switch the display between the laptop screen only, the external screen only or both on together. (Fn + F8?)

It's F540M, I don't have an approatire cable. The laptop lagged sometimes, and when it had a black screen it was only the screen saver. You could hear the laptop. But now when it was the black screen, it shut down completely. Maybe overheated because it was on the whole day?

@Milo Games ,

Can you hear the fan running when the laptop is on even if the screen is black?

Is the fan's exhaust vent clear, clean and unobstructed?

Do you get the Asus "splash screen" before it boots into Windows?

If not(it may be too quick) try starting the laptop and press F2 before Windows boots to go into BIOS and see if you have a display.

This is just to see if it may be a hardware problem or a Windows problem.

If you don't get a display when in BIOS either you really need to be able to connect an external monitor to prove whether it is a display panel problem or a motherboard problem

@jayeff I did not hear it this time, everything was clear. I dont know what a "splash screen" is.I will boot it later, may be a overheating problem

@Milo Games ,

If you're not hearing the fan (or even feeling the air out of the vent) then that is maybe the cause of the problem, CPU getting too ket and shutting down to protect itself

A splash screen is when the Asus logo appears on the screen for just a few seconds when you first turn on the laptop, just before it boots into Windows.

As I said it may be too quick to see it nowadays as Windows 10 fast start speeds up the boot process.

It used to be handy to see it because at least you knew that the screen hardware was working and if there was no screen when Windows booted it most likely was a driver error

Hi,

The laptop is not that old that the thermal paste on the CPU should have to be refreshed just yet.

Maybe you covered the fan vent accidentally or maybe you were watching the video for too long.

By this I mean a long time.

Playing videos uses a lot of resources in the laptop which means that the CPU has a lot of work to do and heats up.

To compensate for this the fan speed is raised to create more airflow to get rid of the extra heat generated by the CPU.

Check when using the laptop if the fan gets noisy because it is running at a higher speed. This is an indication that things are getting hot. If it happens often you may have to open the laptop and clean the fan of any dust etc and also refresh the thermal paste on the CPU.

It was on my bed in my legs so probably. It was just in the beginning of Rick And Morty S1 E1. So that was the problem! THANK YOU DUDE
