My MacBook Air drained out of power. Now when I plug it in, it wouldn't start. I have tried resetting the SMC and NVRAM.
One peculiar thing that I noticed is that the MagSafe power cable is showing orange as it is charging. But when I press the Power key, without holding or with holding, it turns to green and then changes back to red.
The Mac is just 1 year 3 months old.
