That honestly sounds like a bad LVDS cable, but if you can connect an external monitor to it, that would be helpful. You should get some kind of output on the external display if things are working, even if the laptop's display is not on. We need to figure out whether or not the unit is actually powering on and you're just not getting any display, or if it is actually failing somewhere pre-POST. You can also watch the laptop's display very carefully. If you're just suffering from a lack of backlight, you can see a slight change in the display when it turns on, even without backlighting. You can also see things on the display if you look very carefully and in the right light, assuming the unit is actually booting.

I'll try to hook up another monitor to it tonight as well as looking for a failed blacklight. I believe it's a pre-post problem though considering i don't hear the asus post noise when the problem occurs, but i'm willing to try any suggestions of course!

One thing I learned in three or so years working as a computer repair tech, is that it's always a good idea to run tests like this. Especially when the time/effort/expense is essentially zero, even if it's little more than a snowball's chance that this is the issue, it's worth checking. Sooner or later such hubris will catch up to you, so better to remain humble.

So i got home to troubleshoot and make a video and it worked the first try...and the second... and the third. I probably opened and closed it about 5-6 separate times.
I usually run the laptop without the battery. When i went to turn it on, i unplugged EVERYTHING except the battery. Could this be causing the problem?
I've always heard the whole "charging a full battery causes the loss of battery life" and i never really questioned it because the battery was so easy to take out. Does this affect the system? I've ran it without the battery for most of it's life.
Because of the success that i'm having, it makes me think it's because i always had the battery out? But why would that cause the laptop not to boot?
The second i start having these issues i'll record it and update the thread...

It's not out of the question, but let's be thorough just to be sure. Connect all your peripheral devices one at a time, and make sure to turn the unit on and off again several times before adding the next one. If you run into the problem at any point, then set that device aside and move on to another. Then you can go back and retest any devices you set aside to see if they seem to reliably trigger the problem. If everything seems to work great with the battery in, then I might suspect that your AC adapter is starting to give out. Probably a bit of a reach on this one, but if you have a multimeter, you can test the output of the device against what is on the label.

That would do it. The battery will provide a source of back-up power to run the system. Easiest way to test for this is to game on the laptop for a while and feel - carefully! - the charger and see if it is really hot. Also, check to see if the battery has been depleted some. If the laptop battery discharges, then we know that the system is pulling more power than the charger can supply, and thus it is dipping into the battery's reserve to run.

Everything seems to have worked in terms of what i have plugged in. I powered on and off multiple times yesterday and had no problems with it while the battery is in. I'll test out the AC adapter when i'm home today. Hopefully that's the problem because not only are they (reasonably) inexpensive, but it would let me know that it's not a hardware issue in the laptop itself.
I should note that i did take out the battery and tried opening/closing the laptop with only the AC connection and it did in fact work, so maybe the issue is caused by leaving it plugged in like that for extended peroids of time? I didn't want to gamble with it, so i put the battery right back in as that's the only lead i have right now.
