Hey There,

I recently gave my dad my old 13” MacBook (mid 2007 / 2.16 GHz Intel Core 2 Duo/1 GB 667 MHz DRR2 SDRAM/ OS X 10.6.7). Before I gave to him, it had been restored back to its factory settings, wiped clean and then updated to Snow Leopard. The battery was replaced with a brand-new one from a third-party vendor. For the last few months, the battery has been working brilliantly. In fact, everything was functioning in tip-top shape until last night.

Using a 1st Gen MagSafe adapter (adapter #1), I plugged it into the wall and saw slight spark in the wall socket. I then noticed that the green light did not light up when attached to the MacBook. As well, the battery indicator icon in the upper right also showed that it was not being charged. To be honest, I can’t remember if I had the adapter attached to the MacBook before or after I plugged it into the wall. But if I had to guess, it went into the wall first as that’s my usual order of operation. Thinking it might be the adapter, I then attached another 1st Gen MagSafe (adapter #2). I ended up with the same result — no green light or charging battery icon.

With a sick feeling in the pit of my stomach, I plugged both adapter #1 and #2 into my 13” MacBook Pro [early 2011]. They both lit up and charged just fine.

In my previous life, I would have endlessly researched online and tried to troubleshoot every possibility presented. However, I now have a neurological disease that makes it difficult for me to use my arms for more than 10 minutes at a time (this message has been brought to you today by Number 3, the Letter Z and Dragon Naturally Speaking via Windows/Boot Camp.) I also didn’t want to endure all that pain if you guys could just tell from what I wrote above that it’s definitely a motherboard problem… possibly triggered by that stupid spark.

However, if any of you think there’s a possibility that I could be something else, I’m all ears and willing to try whatever y’all suggest. I really just want to make this MacBook work for my dad — he deserves it.

I’d greatly appreciate any ideas,
Jasmine

I believe that model year MacBook used a separate DC input board from the MagSafe Adapter to the logic board. If the DC input board has been zapped, you can replace it for around $40. However, I'm not sure of that. Go to iFixit: The free repair manual and look up that model MacBook. They (ifixit) have some great pictorial breakdowns and step by step procedures for various fixes. They also sell parts.
