Hi guys, One day my macbook pro didn’t charge anymore and from the magsafe port came a high pitch sound. I disconnected immediately. I was not using an original charger for a few years now, my bad, that was probably the reason for my troubles now. I disconnected and made a backup of my files, so the computer itself was still working. As I opened it up I saw that the battery was bloated. I let the battery discharge for safety reasons and ordered a new battery from Ifixit and used the guide to change it. I bought a new magsafe 2 charger from apple. When I was done the macbook pro still didn’t charge or turn on. I double checked if everything is connected properly. I had the feeling that I didn’t break anything (but you never know). I used different outlets, and all that basic stuff. I reset the SMC (like 15 times after every new troubleshooting idea I found on the internet). So I thought that it may be the magsafe 2 in-board. I bought a new one and installed it too. Still the same, my mac is just dead. There are no burns or anything like that, my mac looks pretty nice (now that I cleaned it) from the inside. Any suggestions? Edit: I should also mention that the battery didn’t leak and there were no other fluids in the mac. I did a complete tear down and everything looks good for the naked eye.
Sadly, your system needs some deeper TLC here ;-{ While you could just replace the logic board on your own, you’ll also want to replace the battery as well.

Do keep in mind this is a window to upgrade the CPU and/or RAM as well! It all depends on what your current system offers. If you have access to good Mac repair person nearby then they should be able to fix things too!
Is there a light on the charger?
