I have a 13" A1278 Mid 2010 2.4Ghz. It is a Craigslist purchase, and got it for a very good price, but hope I can fix it to make a great deal.
Symptoms:
1. It will only turn on when connected to Magsafe (see #2), and I have two known good adapters, and it is the same symptom for both.
2. Every now and then, I can disconnect the magsafe, and the system will still run even though it says battery not available. We have done this as long as 1 1/2 hours, even with fan running high speed, and no power adapter connected.
3. Other times, when disconnecting magsafe, the system will immediately shutdown, and then it does a full boot next time I turn it on.
4. The magsafe LED always stays green, never seen it amber, or turned off, when connected.
5. SMC reset does not appear to happen, or at least the magsafe LED stays green the complete time. I also did the SMC reset with disconnecting magsafe, and battery connector after removing bottom plate.
6. Fan runs loud after booting up. The first 20 seconds of booting I cannot hear the fan, but after that, the fan is always running, and the air is not warm, so really doesn't need to run that high speed.
7. The system was obviously dropped based on a corner with indentations from hitting Asphalt, and the LCD has some directional lines showing a shift in the crystals.
8. One of the battery tri wing screw flanges has a crack, possibly from the force of the drop because the tri wing does not appear to ever have had a driver in it.
9. I have not tried a different battery yet since I am waiting on a tri wing screwdriver.
10. Coconut Battery also shows no battery info.
Question: Do any of these symptoms indicate a pure SMC issue, combo issue, or who knows, and what are good next steps please? Thanks.
