Hi everyone, all of a sudden yesterday my Macbook Air 13" I5 started having loud fans and being a bit jittery. This is what I did: reset PRAM and SNC cleaned system cache cleaned login elements rebooted in recovery mode and checked disk (HD was not mounted) > managed to mount HD and run repair, after that volumes looked all ok run diagnostics and then it gives pmf006 and ppn001 (plus ppt002 - low life battery) messages No spillage has happened, nothing stranger than usual. Logic board was changed by Apple in Dec. 2021 By running Acitvity Monitor the CPU load lies at max 60% (mainly kernel_task) and the temperature is 42/43°C… macOs is Mojave 10.14.6 I am scratching my head. Anyone has some suggestions on what could be the issue here and how to fix it? I’d be extremely appreciative of any hint or tips! Update (09/16/2022) Thanks a lot Dan…here are the screenshots from both apps Any idea? Thanks indeed…
Yep! You ned a new battery! MacBook Air 13" (Late 2010-2017) Battery and here’s the guide MacBook Air 13" Mid 2013 Battery Replacement As you can see the cycle could is over the expected cycle count of 1k Determine battery cycle count for Mac notebooks besides a battery life is about 4~5 years which clearly long since passed as this is the original battery! FYI: I use my 2011 15" MacBook Pro system (has a 2012 logic board now) every day doing quite a lot, I’m on my 7th battery, just installed. I get about three years of life per battery.
