Not charging, blinking green/orange light

In my case, my battery is bad! I changed and everything works fine now

I had the blinking light yesterday.

Glad I found this page and that the fix was something easy! I can't disconnect the battery on mine because it's soldered on for my model, so I'm really hoping that it's the charge. It started happening out of the blue, so I ran Apple Hardware Test, reset the PRAM and SMC, and tried a different wall outlet. I'm really hoping it's the charger and not a hardware failure, but I think it's software related because it gets way more intense if I can get it to log in.

In my case when i plug charger nothing happen, no green light and no orrange light. But when I unplug charger “battery status” lights (green) start blinking.
