Hello!! Just purchased a faulty MB Pro 15 Early 2011. It works perfectly when plugged to AC adapter ( I use an original ) but when running on battery it randomly shuts off and I cannot then turn it on. I have to push many times the power button and then ir turns on, as a result I lose all the work going on…. So I got a new battery, but still the same problem. Reseted SMC and the same. I downloaded coconut battery and ran terminal and I get this: Last login: Mon Mar 19 15:51:43 on console Juans-MacBook-Pro:~ juan$ pmset -g batt Now drawing from ‘Battery Power’ -InternalBattery-0 35%; discharging; 0:49 remaining Detailed failures: “Externally Indicated Failure”, “Safety Over-Voltage”, “Cell Imbalance”, “Discharge FET” present: true Juans-MacBook-Pro:~ juan$ Please help me, whats going on, what can I do? I read on some other tread something called the battery controller chip, this might be the problem? Any ideas? Thanks!!
In your first line, you say you bought a FAULTY machine…….. If the last owner cannot tell you what they did to it, to cause the fault. You can’t expect someone on here, to tell you exactly whats wrong with it. You need to send it to an apple repair technician to be looked at.
