Model A1286. Released February 2011 / 2.0, 2.2, or 2.3 GHz Quad-core Intel Core i7 Processor

Won't turn on without cable, won't charge.

Hey guys. Yesterday my MacBook died randomly with 50% battery life. When I pressed the power button there would be no response whatsoever. I then plugged in the charger and it attempted to come on several times, but would shut on and off, on and off. If I leave it plugged in for a moment and hold a couple of keys down I can get it to come on.

When it's on it won't charge (battery icon states "Not charging").

For all intents and purposes it runs fine when it's turned on and hooked up, but as soon as I unhook it it shuts off. I tried resetting the PRAM and doing a SMC reset. Doesn't change anything.

Tried running an Apple Hardware Test but it freezes at 24 secs and gets really overheated.

I've recently replaced the battery, hard drive and ram over the past year for various reasons. Think it could be my logic board? Thanks.

Have you gotten any screen anomalies?

完成的

I did have one yesterday when loading it up at one point. A glitchy horizontal line across the screen that went away after a few seconds.

My bet would be on a failed GPU. There was a class action law suit on this model resulting in an Apple Repair extension Program which has now expired. There is slight possibility Apple would make an exception. I would take it in and result that they run the test. If they won't fix it for free, you're looking at a new logic board. Apple may agree to a Flat Rate Repair on this. Total costs on that including tax and shipping have been $357. Here's the program:

Thanks for the info. I'm going to take it in to the Apple Store this weekend.

It could be the logic board. It would explain the overheating, unrecognized battery, et cetera.

For the battery, the one fix I've seen before is reseating the battery connector on the logic board. That was when a battery was not charging at all, though.

By reseating do you mean disconnecting the battery and then reconnecting?

Also, it isn't really holding a charge either. I have to keep the laptop plugged in for it to work.

The thing is though that it's a brand new battery. The old one swelled up so I replaced it about two months ago with a brand new one. The hard drive I replaced two weeks ago, and the ram I replaced/upgraded about a year ago. That's why I was thinking it could be something bad like the logic board..

Yes, that's what I've seen before (disconnect, reconnect, and then it springs back to life).

It does sound like something's failed here, though. Really, if it were just the battery, I'd think it would start up fine as long as it was plugged in. It's kind of hard to diagnose without having other parts to swap. That said, I believe the Apple Store is really good about running diagnostics on these kinds of things too.

Thanks, I think ultimately that's what I'll do is just take it in. On that note should I expect a charge from them to run the tests?

完成的

No, the diagnosis is free.

I'd make sure the fans are clean and spinning too.
