Chosen Solution
Hello All I’ve recently purchased and fitted a “new” battery bought from iFixit. Basically, my Mac doesn’t recognise the battery, so either the battery is faulty or there is some setting I need to change? As iFixit don’t offer support, I’m hoping I can get a solution here, before contacting my credit card provider for a refund. iFixit really shouldn’t offer a “solution” if the Apple software and hardware environment doesn’t support it. It’s a Macbook Pro A1502 13” Retina (Early2015). What I’ve done so far: Disconnected and reconnected the battery (This did resolve a non-responsive keyboard and trackpad).Reset SMC,3 timesRun First Aid on Disk Utility Other observation/issues: Unit is powered with mains power cable when this is removed the unit switched off.The charger shows amber light.The unit runs VERY slowlyBluetooth and Wi-Fi are not available as options. Luckily I’m able to plug in an ethernet connectorThere is no battery indicator on the desktop. Any insights or suggestion would be great. Thanks Symon
I had a similar issue with a late 2013 MacBook Pro retina. In the end what worked for me was: Disconnect the battery connectorConnect the charger and turn on the MacbookTurn it off and disconnect the chargerConnect the battery connector again The next time I turned on the MacBook it recognized the iFixit battery. It was almost like it had to be powered on without any battery to then notice when the new battery was added. Funny enough, back in the day, I used to use this trick with 133MHz SDRAM when the PC wasn’t detecting a module. Be very careful while turning on the MacBook with the lid open, you don’t want to short-circuit anything!
With Apple computers, if the battery is bad or not recognized the computer will be very slow. so that is normal. Unfortunately, I have had my fair share of bad batteries from iFixit. They have a great return policy so you won’t have to dispute it with your bank. just let them know your issue with the battery and they will either refund you or send you a new one. With Apple computers, it should recognize the battery right away when you plug a new one in without having to do any reprogramming. So being that it doesn’t recognize it. It sounds like there is either something wrong with the battery or the main logic board. but it’s more likely to have an issue with the battery.
Many newer laptops with mini chargers absolutely need the battery to provide extra power when the cpu clocks up. Also most units now use both an age & genuine check. If the battery wasn’t “fresh”, you’ll have all the problems you described. It’s not the actual battery cells that are bad, probably bad data on the “on battery computer”. Batteries aren’t dumb anymore, they have their own data and safety processor. I used to rebuild batteries & reprogram them as certain computers could never recognize a “replacement”. I know there are some battery utilities out there to update the date & recalibrate the unit. Probably not an option, but there may be one out there.
