Good Day Everyone I’ve just replaced the battery with a kit, work was fine. I turned it on performed some tasks and turned it off. I made an SMC reset and it won’t turn on, not even fans after powersupply connected. I found a temporary solution disconnecting and reconnecting the battery plug (2 to 3 mins between those steps). Then after plugging the magsafe (light is functioning properly) fans spins and it boots. At the present I’m performing calibration to see if changes. Any suggestion? previous experience? Thx alot ?
Well, your battery and the charging logic is just fine! So we need to run diagnostics as you have a different issue. You likely damaged something in the process. Restart your system and press the D key to enter, let us know if you get any errors. Reference: Mac startup key combinations
