ASUS laptop FZ50V wont turn on please help

First what happened was i returned from letting it idle to find: the screen was off, the display lights showed it was on (not asleep), and the mousepad/keys wouldnt bring it out of 'sleep'. I've had this happen before-- sometimes when the screen shuts off to idle it won't respond to wake back up, and the only thing i can do it hold the power button to hard shut it down. Annoying, but I've tried everything sites like this tell you to try and it still happens. This is however, i noticed there was one thing different before i shut it off. The battery button was orange instead of green. But i didnt think much of it until i came back to boot it up again later.

I push the power button and the indicator turns on, the LEDs with the lightbulb and lock with an 'A' both turn on, and after a moment the battery light turns on green and begins a slow blink. Otherwise, nothing happens. No screen flicker or anything. I hold the power button to try and turn it off again and it won't even respond to that. After varying amounts of time, the fan will start running on what seems to be high, despite nothing else running. The only way to turn it off is to disconnect it from the powersources, both battery and cord.

I've tried removing the RAM and putting it back, nothing changed. I've tried using only the cord without the battery, it simply does the same thing upon being plugged in instead of me pressing the power button.

I don't know what to do, all I know is i really need it to work because I have way too much on it to lose.
