Hello everyone,
I have a macbook pro mid 2012 13 inch that I recently fixed by replacing the logic board. I am just curious to understand what must have caused my logic board to stop working. Here is a chronology of events.
About a year and a half ago the loading bar when you turn on the macbook would freeze 3/4 of the way. I took it to a technician and determined that the hard drive was broken. I got a solid state drive and everything was smooth sailing from there.
A couple of weeks later, my macbook started to make three peeps and began to get very hot after I had turned it on and left in sleep mode. I did some research and found that it was a RAM issue (I have 16GB of RAM). I took out the RAM and reinstalled them. The same problem with the three peeps would come and go every couple of months.
A couple of months ago, I would connect the magsafe charger and it would not charge until I turned on the laptop. After which, the slightest movement on the magsafe would cause the light on the magsafe charger to turn off but would still be charging the computer.
Then, a couple of weeks ago the battery icon would not show up on the top right of the screen. Over the phone, Apple did a diagnosis and I got three error codes. PP01-something and two other ones. Basically, that the battery was not detected, nor was the RAM, and that there was a problem with the SMC. I tried a new charger and nothing changed. Finally I bought a new battery and while that solved the "battery not detected" issue, it did not solve the other problems.
I ended up changing the logic board and that solved everything.
Note: The old battery (the original battery that came with the macbook which I bought new from the store) had about 1700 cycles. Despite this, in system settings it said that the battery condition was normal. I also replaced the magsade DC-inboard that is connected to the logic board with a new one and that had no effect.
I understand that my laptop is nine years old. But what do you think may have caused these problems? The battery with too many cycles? The original logic board had an intel i5 2.7GH processor. The new logic board I installed has a i7 with a 2.9 processor.
thank you.
