Hello. I have an old macbook 2,1 (late 2006). The battery is long dead, and i have been using it plugged in.(I recently got it as a browsing laptop for my parents). Since i got it, the charger had a dim green light. I thought that this is because it didn't had a battery. It worked fine until a few days ago, when it didnt boot up. When i press the power button, the LCD flashed for a split second then turns of. The fans start up, and the light indicator in the bottom of the laptop stays on. I tried removing the RAM modules, and the light still stays on (it should normally blink). I tried the charger with a similar laptop (early 2007) with no battery, and the green light on the charger is not dim, indicating my laptop had a problem even before. Any idea on what the problem might be? Is it the logic board, or could it be a corrupt firmware, or a problem with the power connector? Tried SMC reset, did not help. This problem (laptop not booting) happened a couple of times before. The solution was to unplug the laptop and wait 15-20 minutes. After that, it would work. But this time, it didn't.
