Battery not connected consistently
I got a problem with my Macbook Pro Mid 2012 recognizing its battery. At some point while using it it suddenly shuts down and won’t start again unless I plug in the power adapter. In this case system stats show that the battery is not being recognized. My first attempt of solving this problem was to pop the bottom cover off, disconnect and reconnect the battery cable from the logic board - pop the cover back on and suddenly it starts working again as if nothing happened.
Unfortunately not for very long periods of time. Sometimes hours, sometimes days. This behaviour is very consistent. It shuts off, I reconnect the battery, it starts working again for a limited period of time, it shuts off again and so on.
Then I ordered a new battery, the old one was kinda weak anyways. But the new battery didn’t solve the problem either.
Here are some coconut battery stats (this is with the replacement battery) directly after the disconnect reconnect game.
Some more information about the history of this laptop: I bought it used and non functioning from a friend (suddenly stopped working and won’t turn on again) for a very low price so I tried my luck, sent it to a repair company in Berlin to have them have a look at the logic board. They replaced the display cable and the charging electronics (that’s how they called it on their paper). I didn’t mind cause I got a working macbook for a good price including the repair that lasted me about 4 years until now. I put in more RAM and a SSD and for some time I used a SATA3 adapter to use an additional HDD instead of the optical drive. sooo…
Any help how to proceed further will be much appreciated :)
