Title:

Why won't my MacBook Pro power on?

Text:

I have a early 2008 15" Macbook Pro. It's got the 2.5 Ghz C2D. I received this unit for free because it won't power on.

I ordered a new "T" Magsafe adapter right away and tried it. I get no light on the Magsafe adapter. I tested the Magsafe on my other Macbook Pro and it works fine. I also tried the "L" new style Magsafe Adapter on the broken MBP. No light.

So I took it apart and removed the Left i/o Magsafe board. I purchased a good known working replacement. I just installed that today and I still get nothing. No light on either Magsafe Charger. So it appears that the SMC isn't activating the Magsafe board. Unfortunately the battery was completely depleted when I received the unit, so I can't test that.

I'm trying to restore this to good working health. Does it look like I need to buy a new Logic Board or are there other things that I can try? I did reset the SMC and that didn't do anything. I'd appreciate your input!
