ASUS N56V randomly stopped working

This morning I took my laptop to the first day of my last year of college and the battery ran out close to the end of the class. No problem, I had done everything I needed it for. However, when I plugged in and reopened the computer a couple hours later to do some work, I found that it would not turn on. That is to say, the power light would come on and the insides would whir for a second, but the screen remains completely blank. Not even the deep black of a pixel choosing to be black, just the black of not being on at all.

I tried taking the battery out, releasing the extra charge for a minute, powering it on with the adapter and no battery, etc (and every variation on that sequence of steps) so I don't think it's a power issue at all.

They keyboard seems fully functional. The caps-lock light turns on and off. I can access the bios, albeit in total blindness. I learned this by a solution that one person on a forum recommended. (I lost the post, but it said to press F2 immediately after startup, then: F9, enter, F10, enter. This caused the computer to apparently reboot (the keyboard backlight flashed again) but with no change in the blank screen.

I've spent about an hour googling and trying little fixes, but nothing has worked. A lot of other threads on the subject end by saying that it just has to be sent to ASUS for repairs, but seriously? It was working this morning, the battery died, and now it won't? What could have possibly happened in those two hours WHILE IT WAS OFF that could be causing such a huge problem?

Thanks in advance for your help.

 

I guess (with weight on guessing) it could be the cable to the lcd. Or the intel eprom that got stuck in a mode or other and won't reset. The eprom thing happened to me once after the power went out in the middle of a "hibernation". Add some asus-special acpi tweaks, mix a little with intel graphics drivers, and the entire thing refused to boot once the bios didn't detect a vga device, or something like that.. not that I could see what the message fault was. So before you send it to repair, maybe try booting it up with a vga or hdmi cable to a monitor, and see if anything changes. Then "properly" shut it off, and try again. On my laptop, the lcd came back on immediately after the vga was detected. You know... I've literally no idea what the logic behind this stuff is. But might be worth a shot before sending it on repair.
