I have had this laptop for over a year now. The other day i restarted my computer and the screen was flickering. After about 30 minutes the flickering eventually Stopped. My computer started to update and restarted itself again and now the screen is just black but the computer is putting out video through the HDMI port. When viewing the computer on my TV i realized that the computer was not even recognizing the Internal Display. I believed that the screen was just going bad, but then i performed a hard reset and the backlight came on.While the backlight is on the bios will not even load its just a black screen with the backlight. So then I assumed it was the screen but not the backlight. After restarting the computer a couple of times with just the backlight on, a red dialog box comes up talking about a secure boot error and when I press enter it takes me to the bios. After getting into the bios I realized that the screen is fine. Now when I get into the bios Secure Boot is on so I turn it off and the computer boots but the screen is once again black and video only comes through the external monitor. And when I turn secure boot back on the backlight is on but the bios just does not load at all. What could be the reason behind this?
