Macbook Will Not Power On

My macbook recently failed to wake up from sleep.

Here are my current symptoms.

With magsafe pluggged in, LED glows green on adapter.
Battery indicator flashes full when tested.
White LED on front panel of macbook does not light at all.

I have:

Removed all accessories.

Held down the power to force it off.

Removed the battery and the adapter, and then held power for 5 seconds.

Tried to reset the Reset the PRAM.


I am dreading that it's a logic board issue, but thought I might be missing something.

Pressed the control key, the command key, and the power button simultaneously and hold for three seconds to try to restart the computer.

Any ideas?

Thank you.
