Beeps 3 times won't boot soldered RAM A1502 MacBook 2015

Beeps 3 times and doesn't not start up. RAM is soldered so I can't re-seat or clean and place it again. Please help, how to solve this problem when the RAM/memory is soldered in the logic board. Thank you.

Sadly, you need a new logic board. I would go to an Apple Store and give them a piece of my mind!

Do make sure you didn't get your system wet or have big dents in your system.

Thanks, Dan for your answer. The MacBook doesn't has any dent and wasn't wet. Any suggestion which part of chip/component I need to replace in the Logic Board to fix this problem.

If this is a logic board issue, please let me know which component of in logic board do I need to replace. The RAM seems fixed/soldered in place so, by good guess that RAM should be good.

完成的

Not so simple! Any one of the RAM chips could be bad or the PCH. I can't tell you which chip. Thats why you need a new logic board.

Apple owes you here! If you push they should replace it for minimal cost.

Hi Adrian,

As @danj said, you most likely will need a new logic board. If you can get Apple to fix it for free or relatively cheap, go that route! However, if you are unable to get the help you need from them, we sell 3 different models of logic board for your particular machine, depending on which sub model you have. They aren't cheap, but they will fix the problem:

2.7 Ghz Logic Board

2.9 Ghz Logic Board

3.1 Ghz Logic Board

Good luck with the repair!
