Asus_USA :
Can you get into the BIOS at least? I'm not quite sure what you mean by "abilitated" but I would contact support to see if they can walk you through the necessary troubleshooting steps.
No just black screen, don't know if i can get into bios, i tried to press f2 and then f10 and enter that i remember should go in bios exit and save and reboot computer but the pc don't seems to reboot.
Italian asus assistance is absolutly crap. When i had to buy another asus pc after having fought with italian assistance for their ignorance i contact the usa one that eventually cleared my doubts. For this problem italian assistance said: "Seems an hardware problem, get a RMA".
Hardware problem???? I just put UEFI boot on enabled in BIOS and reboot a notebook that until that moment never had problems. Without warranty it's about 100 $ just for a look, without the reparation. This is a robbery.
