Chosen Solution
I performed a successful battery replacement with an iFixit kit per the amazing tutorial here: MacBook Pro 15" Retina Display Mid 2015 Battery Replacement / The replacement worked, the new iFixit battery was found in the system report, and I performed calibration successfully.After a few (2-3) days/cycles, the battery seems to have completely “vanished” - no longer visible in the top bar or system reports
. Now whenever the laptop is disconnected from the MagSafe power adapter (always orange now after the initial green flash when connected), the laptop simply loses power and must be reconnected and rebooted. Coconut Battery doesn’t seem to see the battery at all.
I’ve tried visually inspecting the battery connector (looks fine)
and re-attaching carefully to the motherboard, but no luck. Has anyone else seen/fixed this? I’m hoping I won’t have to repeat the painstaking (and expensive) process of replacing the whole battery assembly.
Sorry the batteries micro controller chip failed. You’ll need to contact the store to get a warranty replacement if you got it in the last year. Dig out your paperwork and contact them iFixit Customer Support
