MacBook Pro 13" A1278 won't power on

I bought 13" MacBook pro A1278 unibody. Used AS-IS for 80$ (negotiated from 140$) off of a classifieds app.

The person said it doesn't power on and they don't know why. They said "doesn't turn on maybe water damage" is what they put in the ad literally. So I took a gamble and bought it with hopes that it could or can be fixed.

I inspected the laptop and there's no signs of water damage as in: the keys aren't sticky, there aren't any liquid stains, screen looks like in very good condition light scratches no cracks or etc.

One thing I did notice was the "magsafe charging port" looked a little dark or "burnt" on the hinges and prongs of the port. As I seen and read that could be a cause of it not turning due to it not receiving power properly and not charging I assume?

The person didn't give me the charger with it so I can't really plug it up to see if it's the charging port that's causing it not to power on. Since its not powering on in had thoughts in thinking maybe the battery went bad and needs replacement?

Also I noticed on the bottom that 2 of the screws are missing so the previous owner probably took off the back and maybe tried to see what's wrong? I don't know.

The laptop is in overall really good condition with light scratches on the screen and aluminum housing. And with only one mini dent on the corner.

I just want to know what I should do if anyone has had any similar problems with their macbook pro not turning on and what I should do?

I was thinking maybe buying OEM new magsafe charging port and new OEM apple macbook battery for the laptop and having a very reputable laptop repair shop fix it? Maybe seeing if that would maybe fix the problem?

I really don't know what to do and don't want to waste any money or time unless I know there's a good possibility of the laptop having a chance of being repaired which I'm pretty sure it can but I just want to be sure and know what to exactly buy and do.

If any of you tech guys/ Tech Junkies/ Experts could lead me in the right direction of what I should do with MacBook pro? It would be highly appreciated..

Where do you live? With what you have into it, you might do better sending it to a pro who has spare batteries and parts and mag-safe adapters. What concerns me is the source and that it may be locked.

I live in Dallas Texas. I was thinking of taking it to a really good repair shop and buying the parts I think it needs. And having them fix it. And what do you mean by "may be locked" ?

It the machine had locate my Mac turned on and is not being sold by the original owner, it may have an EFI lock on it making it unusable. You can always put it in a Flat Rate box and sent it to the pro in Lubbock.

Oh okay I had a feeling that's what you meant by that. Also could you give me the exact name of the Repair shop that you're talking about that's located In LubbockTX? I've searched in Google

And seen other shops but not the one you exactly mentioned? Thanks!

Another thing I just found out that my MacBook is a " MacBook Pro "Core i5" 2.5 13" Mid-2012" by searching the serial number located on the bottom of the laptop.

Try following the instructions on this repair guide:

MacBookPro does not power up on AC power or battery.

MacBookPro does not power up on AC power or battery.

Also, perform an SMC Reset after doing a power cycle.

I just ran into an issue with my Early 2011 13" MBP where it would not power on. It may be a simiple fix! All i did was unplug the battery from the logic board and held the power button for 10 sec then plugged it the power cable while still holding the power button for another 10 seconds. I released then pushed the power button - it powered on. I shut it down - unplugged the power connector. Then plugged the battery back into the logic board. I finished with an SMC Reset - it differs by your model - if the battery is removable or not. Your mac doesn't have a removable battery I don't think.

I hope it works for you! Good luck!

I'll leave the reparing to the pros lol. Don't want to take the risk of messing it up more than it already is.

Another thing I just found out that my MacBook is a " MacBook Pro "Core i5" 2.5 13" Mid-2012" by searching the serial number located on the bottom of the laptop.

So with that being said I have a version with a removable battery if I'm not mistaken?

UTM India is one of the most popular MacBook Repair Service Centers in the world. So today we will talk about what can be the reasons for the MacBook not turning on. As MacBook gets old, its internal memory gets degraded due to prolonged usage. And after some time its battery also starts charging slowly.

Suddenly the MacBook shuts down.

As soon as you open it to work on your Mac. See that now it is not opening. So you get nervous about what has happened to it all of a sudden. So do not panic, read the steps given below and follow them.

Boot your Mac.

Boot your Mac one more time before you decide to take your MacBook to a repair center if it won't power on. charge Mac Hold the power button down while it's on and take it out. Do you hear any fan sounds here? Your Mac has a problem with its software if you hear that. In addition, if your MacBook Air or MacBook Pro doesn't work after frequent attempts, there may be a hardware issue.

Stop your Mac.

Check your performance after unplugging all cables and staying on power for 10 seconds.

Your MacBook may not turn on in rare cases if the display is malfunctioning. If the power circuit is malfunctioning, the screen light may not be triggered.

You can solve this problem by placing your MacBook Air in front of a bright window. Your screen will turn on after that, and you will be able to log in.

If your MacBook Air does not turn on after following the above tricks, take it to your nearest MacBook Repair Center and have it fixed as soon as possible. Always back up your files, as you never know when your system might not work.
