I was brought a A1278 to swap a logic board. Done two (2) boards in it now. Neither has given me luck. It is a 2ghz, 2gig ram, 160gig hd part number MB466LL/A I get a orange power cord indicator when plugged into it, but nothing else. Hit the power button and nothing. Checked my connections twice or more on both. I've done approx 75 boards (pc laptops) in my time, so no newb stuff going on. I work in the industry. Curious is someone else has had similar problems. Maybe it could be power button issues, cable probs, keyboard, et cetera. Any help would be great.

Also, who is a good source for keybords, power buttons, et cetera for this model? Thanks guys.

I really wish someone would answer this question. I have also replaced more boards than I care to count but this one is driving me crazy. Bought a brand new logic board for a1278 and still no boot. It has a new battery, there are no pinched or burnt cables, everything is plugged in, and full charge on battery. STILL NOTHING PLEASE HELP!
