Replaced Logic board, green light when plugged in but won't power up
Ok, so I have a late 2008 15" MacBook Pro and the original logic board is 2.5 ghz, but i've searched and searched and I can't find a decent one for a decent price. So I went on ahead a bought a 2.4 ghz, now that i've installed it, when I plug in the charger the green light comes on, but it will not power up.
Is it because I bought a 2.4ghz instead of a 2.5? Please help me out. Oh the battery was removed as well when I did this.
Is this a good question?
