Followed the battery replacement guide - turned on and worked great - for 4 hours or so - now I can’t get it to boot up past the Macintosh chime, but can hear the fans very quietly spinning. I tried the SRC reset and the nVRAM reset with no success. Does anyone have any ideas? Best, Patrick
is the connector from the battery to the logic board connected properly? Does the light from the charger go to orange when charging it?
