Okay so I closed the lid on my laptop 5 days ago and unplugged the battery charger. Now 5 days later I tried turning it on and obviously the battery was probably depleted. I charged it for one hour and now when I press the power button it blinks green. When I hold the power button it blinks white in 10 seconds and then nothing happens. What can I do? I need help!

edit: when the green blink comes on the laptop gets warm but I hear nothing and the screen is black.
