Does not power on. How to check if it's the motherboard?
My friend's MacBook Pro a1297 (from 2009) does not power on. Is there a way to check whether the motherboard is fried or it's just the DC-in board?
Generally, is there a way to check (at home) if the motherboard is working?
Edit: It seems the battery is not working, because the green LEDs flash five times when the battery check button is pressed. The laptop does not start even with the battery disconnected.
Even with the original mag-safe, the LED of the charger stays green. All battery testing LEDs flash five times.
