Won't turn on and the Magsafe light stays green
I was sitting around on my computer when it ran out of battery and died. I plugged it back in and now it does not charge, the light stays green and does not turn amber. In addition, when it is plugged in and press the power button the sleep light indicator flashes rapidly and is accompanied by a beeping noise. Don't know what to do.
Это хороший вопрос?
I have similar problem with an old MacBook Air 2008 which I am trying to squeeze a bit more life out of. 6 months ago I replaced the battery, but we have been away due to Covid so it hasn't been charged all that time.
The battery has 0 percent charge now, But it says the battery life is good and it hasnt been cycled at all. (It only runs on the charger).
When I charge it the charger connector LED is amber for at least 20 minutes then it goes green. So you would assume it has got enough charge. It will not boot on battery only. But when I boot up, it still says the battery has no charge.
I have checked all the connections and resetting the System Management Controller.
Has anyone got any ideas what to try next?
