Hello, I have a Macbook pro mid 2012. Recently I had to change battery, for a greencell battery. I installed it. But now, when I am charging the notebook sometimes randomly the laptop suddenly changes its screen to black..i have to wait 2-3 minutes, it shut’s down, after I press a key, (no loging in screen) and everything is opened, when it shuts down..
I tried, recallibrating the battery, I tried SMC reset, NVRAM reset, setting the sensor motion to zero from terminal..but nothing helped…

Ps. When I am not charging the laptop, the error(black screen,shutting down) does not occur…
Any suggestions please ?
