Changed out the EFI chip on this MacBook Air and now it won't power on
I recently bought an Apple MacBook Air, and stupidly didn't check to see if there was a firmware password on it or not. The old owner doesn't know the password. So, I purchased a pre-loaded EFI chip for this specific model (a1466 EMC2632) and followed a tutorial on youtube on how to replace the EFI chip with a heat gun and flux. I did so, and I reassembled the logic board and doubled checked to make sure every cable was plugged in properly. I plugged in my MagSafe charger and it doesn't show a green light. I pressed the power button and nothing came on, no sound, no battery symbol.
I thought maybe the BIOS chip was bad, but would that prevent the entire computer from powering on? The battery is still good, the cables are all plugged in securely. I don't know what exactly could be causing this, as I didn't do anything other than heat up the EFI chip and replace it with a different one (which is from the same model MacBook Air). I know the charger works properly because it charges my MacBook Pro just fine.
any suggestions? Is there something that could go wrong in re-mounting the logic board?
Es esta una buena pregunta?

Did you ever get anywhere with this? I just changed a chip on mine and my charger does have a orange charge light, but doesnt power on. Not sure if my battery is dead or I may have to try goin back to my old chip. If you were like me and got the chip on eBay from china I guess being defective is an option...I used a reflow oven so pretty sure nothings out of place.....

If the chip is not soldered properly, the Mac will not power on at all.

Did you ever figure out what happened? I tried doing the same process with my macbook pro but unfortunately the laptop wont boot up. Right now I have my laptop charging. Whenever the white light blinks while being charged I hear a noise from the hard drive and the fan turns and that process repeats itself. Any suggestions?
