"Found this problem and already fixed it! my computer is Macbook pro retina 15"" mid 2012. i bought new one from my local shop and it cannot open without plug magsafe. the battery status say ""not charging"" use power adaptor as source. even magsafe light is orange. also say ""replace now""

Cause of this problem is the new battery have no remain charge and it absolutely 0% . I done many things in this post and other. (reset smc, pram , everything) and it useless.

So i shutdown. replace battery with original one (The one that come with your computer) then Boot it, plug magsafe (power adaptor). and check battery status, it should say ""charging"". Then shutdown , remove magsafe, remove original battery and replace it with new one. Then plug magsafe adaptor without try to press power button. you should plug magsafe first and only! and your computer will automatically boot. Finally, with some luck. the battery status will say ""charging"" maybe it also say ""replace now"". Don't worry, Let it charge like 10 minute and shutdown , Start it again. Your battery should say it have normal condition and everything should work fine.

Thank you for this post and all you guys, hope you all can fix this problem with the way i can too :)

ps. sorry for my bad english."

"New batteries need to be charged before use. New batteries are known to fail straight out of the box on occasion (especially cheap Chinese ones) . Contact your vendor about the battery. In the mean time try removing all power (main and battery) for a full 24 hours before reconnecting any power might solve your problem. Start by connecting the battery but not powering up. You do not need to completely button down the top case, but put a few screws in tight enough that the ribbon cable will stay connected. Attach the main and see if you get a red (charging) light. Let the battery completely charge before attempting to boot.

If this answer is acceptable please remember to return and mark it."

"Guys,

I replaced my battery with a ""alternative"" one and every time the battery goes flat the MacBook won't recognize it anymore so it won't charge it. (as describe but everyone here)

But if I connect the MagSafe and press Option+Shift+Control+Power for around 10s it will work! MagSafe light goes green then red and battery starts to charge.

I am not sure about the correct sequence so try:

- Press the buttons and connect the MagSafe.

- Connect the MagSafe and Press the buttons .

- Connect the MagSafe, wait a bit and Press the buttons .

Cheers"
