My display won't come on just black screen

W890711W4R3 is my serial number an A1185 my model #

my screen will not come on I plug the charger into it it turns green then goes to orange,

I press the power button to power it on an it makes a loud beep noise! Then I notice the white light flashes

on the front when it beeps, I turn the laptop over an the first light on the battery is blinking green nothing else

Happens.

I unplug the charger an try to start the computer without being plug up an it died the same thing!?

What is going on here? I'll pay for repairs I just want it working again.
