g580 does not switch on

It does not switch on and three lights on the front are off. Could it be a problem with motherboard or something else?

Could be due to bad a battery or charger, I would check to ensure that the charger is working for starters.    It should be putting out 20V DC and at least 3.25A for a 65watt charger.    Check the DC-IN jack too.

I disassembled laptop, at the connector that attaches to the motherboard there is voltage. What else to check?

Follow the power traces from the AC connector to Battery in rush (charge) loop, then other points on the board.

What led up to the "not turning on" situation?
