My laptop is no longer charging when plugged in and magsafe stays green. Laptop will boot but shut off after a few seconds of the Apple logo and the loading bar showing Cleaned the magsafe adapter and the magsafe port on the laptop. Reset the SMC, holding down “shift, option, command, and power” for 10 seconds. Installed a new battery and bought another magsafe adapter today. Reset the SMC again. Laptop ran on the new battery but didn’t not charge. New battery is now drained. Battery indicator flashes 3 times when plugged in on either battery. Both magsafe adapters were plugged into different outlets and the magsafe stayed green on both.
Update: Here’s a few photos with it now running on just the adapter.
Are you using an 85W MagSafe 1 charger? Also there are a lot of bad / faulty A1286 batteries out there.
