So I have a hp spectre 360x convertible 15-eb1043dx and several weeks ago the screen would not power on. I did all I could as far as trying to reset bios ect. I just put a new motherboard in and it still don't work. Keuboard lights up but nothing on the screen. I have had the laptop for 2 years and it don't work $1600 is a lot to spend for only 2 years of use.
