I have to disconnect the battery too often to turn on this mac
So i got given this “presumed to be dead” mbp 15” retina mid 2012. It was not working at all and seemed really completely dead.
I decided to give it a chance and went through the traditional starting up procedures: SMC reset, PRAM reset .. etc still nothing! no charge, no way to turn it on at all. With some hope i decided to go for the ultimate revival procedure: disconnecting the battery and pluging in the charger! and MIRACLE the chimes sounded and it started.. !
Then i have reconnected the battery , and it started up and begun charging normally .. i could wipeout the ssd drive and installed catalina and everything seemed to be working just fine.
After a few days of normal working conditions, the mac died again! it just returned to the same brick state as when i got it.. so i had to remove the back cover, disconnect the battery again.. and it started again. Then a few days later after normal use, it happened again and its gonna be for the 3rd time that im disconnecting & reconnecting the battery.
What could be wrong and what piece of hardware is causing this? the number of charching cycles of the battery is only 172! there is no other faulty conditions. I have noticed when i drop the mac on the bed or lay it on a table, or flip it over.. it is when it will never restart again ! and this requires to disconnect the battery again
thanks for pointing me out what could be wrong with this mac.
as you can see, coconut shows the battery status of this mac book pro as +90% healthy, why i should remplace it? (i have already looked into the battery remplacement procedure, and in no way im ready to do that myself) as for now, this battery works just fine. this mac book pro has something else glitching or broken, and that is what i’m trying to find out. TIA
ps: possible clue : fault with the SHOCK SENSOR -but how to investigate and test this one to make it sure?
