Chosen Solution
Just replaced the battery with a replacement from here. When I plug the charging cable in, the charging symbol appears next to the battery percentage in the top bar but when I click on it says ‘Battery not charging’. Here are the Coconut Battery results. Any help gratefully received. I tried resetting SMC by unplugging the battery from the logic board (I didn’t take it out completely) then pressing the power button for 5 seconds, then reconnecting the battery.
Update (01/12/2021) I have had the laptop plugged in for 1 hour and it has gone up from 62%-66%..? But still saying Battery is not charging.
Let’s review a few issues you could be facing. The MagSafe cord and connector maybe worn or damaged inspect them for bumps or cuts and for the contacts are the clean and the four outside contacts at the same elevation?
The outside pins are damaged! Now looking at your system how does the MagSafe port look? Nice and clean and are the contacts nice and shiny?
Clearly one contact is in bad shape here! Is your MagSafe a REAL Apple unit?? Most people can’t tell the knockoffs from the real! ● Don’t Replace Your MacBook Charger With a Cheap Knockoff ● OEM MagSafe Chargers vs Cheap Imposters: Teardown for Truth ● Lacking safety features, cheap MacBook chargers create big sparks ● FAKE Magsafe MacBook Chargers on eBay - Watch before buying a Mac Charger Lastly what is the color of the MagSafe LED Amber or Green or not lit?
Most likely the isl6259 charge controller and associated mosfets that wear at same time. It’s cheap to do but does require a eBay spec hot air station at max heat and eBay lcd microscope.
