标题:

MacBook air won't power on

文本:

Hi Everyone.

I have a Macbook Air 11" Mid 2013. It is working perfectly except that it won't power on after it was shut down. To power it on, I have to do the following steps:

1) Remove back cover

2) Unplug battery cable

2') Plug battery cable in

3) Plug megasafe in

4) It turns on automatically after about 5-10 seconds. No need to press power button

Note:

- Step 2 is the most important step. Without unplugging battery, it won't power on by any methods including megasafe plugged in.

- Step 2' is not important. It will turn on without Step 2'

- Power button is working when it's ON. When it is completely OFF, it won't power on by pressing power button

- When it's ON, it can be restarted by Press Power Button --> Select Restart; or Select Apple logo --> Select Restart

- When it was shut down, it won't power on except above method.

- I have tried reseting SMC, NVRAM but won't work

- Megasafe LED is on when plugged in

Any comment or suggestion would be highly appreciated.

Thanks,

Happy New Year 2017!
