Hey Folks. while Battery doenst charge, ich found in the MacUser-Forum the Trick that this issue may can be fixed with de-connect the Battery, then press the Power Button for 10 seconds and then re-connect the Battery. i did so - now my OSX isnt able to boot (before the Manoever above it worked perfect) now i just see this “other bootbar” and when it reaches 35% the MacBook went black and it had turned himself off. Any Ideas?
Have you tried to boot with Command - R and try to reinstall OS that way?
