Solved! Strange cracking noise from the lower part of the screen

Jan 15, 2019
I have an Asus laptop (15.6'' VivoBook Pro 15 N580VD) and a couple of weeks ago it started to make a strange noise (like cracking or something) when opening the lid and when touching the lower part of the screen. It works just fine but that sound drives me crazy because i'm afraid that something is not properly fixed and it will brake.

You may want to turn the volume up a little to hear it better) :

At first I thought that the hinges may be the problem, but the sound comes from the part the conects to the screen rather than the side where the hinges are.

If you guys encountered the same problem or if you have any suggestions, please let me know!
