Hi guys. I bought a new battery spare on iFixit and I’ve install it on my mac. Everything is apparently ok. But it happened to me that the battery level was around 14% and the mac turned off without any screen message. It did want to turn on until I connected the magsafe. Unplugging the magsafe caused another immediately shutdown. So i left it plugged for some time and now it is properly working. Suggestion about which is the problem affecting my new battery? Thanks Update (09/09/2016) Guys, thanks for replying me. Well, I did the SMC reset procedure as reported by Apple (connecting the magsafe, i pressed control-alt-maiusc at the left of the keyboard and power at the same time). I was sure the procedure got successful because the magsafe led turned green and then orange again. But apparently this not worked in my case. So i decided to open again my laptop and I performed the procedure reported not for Macbook Pro, but for the MacBook, i.e. I removed the battery and pressed power button for >10s. Now it properly works! This laptop will never die!!! Thanks again Update (09/22/2016) Hey guys. I’ve got a new problem now. After some days, I’ve got again the message “battery requires assistance”. What’s wrong now? This is the screen which reports the battery information: https://i.imgur.com/3MDbIGb.png Some suggestion? Is the battery that iFixit sold me not good?
You might want to consider resetting the SMC: https://support.apple.com/en-us/HT201295
What does the system information battery information say? You can run this directly under application/utilities folder. Look under power section. At the least, the battery health condition should be normal. Other than that, do a SMC reset and charge the battery to 100% and let it drain couple of times and see if this problem goes away.
Hello! I have the same problem… SMC Reset done, but no change. Battery removed, pressed Power Button, no change. When it´s about 7-9%, the macbook turns off without warning. Any more ideas what i can do? It´s a new battery from ifixit (SMP). Thank you!
