Asus laptop battery light blinking white

I have an Asus N580 laptop. When I turn it on it does not boot (no POST), black screen with no logo, fans are working, LEDs are blinking. What I want now is to understand what these LED errors mean:

  • Power LED is ON.
  • The battery LED is blinking white: two blinks and pause, then again two blinks and pause.

What I have tried to understand what these LEDs mean:

  • When I disconnect LCD cable on motherboard then battery LED blinks four times then pause. This definitely means no LCD.
  • When I take out memory it still blinks two times and then pause.

I could not find the meaning for Asus LED error codes anywhere on internet. Does anybody have the reference to the meaning of these Asus LED boot errors? Thanks!
