Hello I just swapped a old battery for a new one, no problem changing the battery. (Mid2012 model) But after i got it all together and trying to turn on the machine, nothing happens. No display, fans, chimes, all dead. The charger is green for the first 3-4 seconds when connect, and goes orange after this. I measure battery with voltmeter and its it showing 10v. I tried resetting SMC and PRAM. (When i reset SMC i see light on charger goes green, and back to orange again) I have testet with 2 brand new batteries, and the old one, still dead. Does anyone have any tips/clue here? Thank you!
The charger is doing what it’s supposed to. Let it charge up for a few hours and wait till the mag-safe light turns green, then give it a try.
