How to turn on my MacBook Air?

To turn your MacBook Air on, you have to locate the power button. If you have look at your keyboard, you’ll see the power icon or unmarked black square on the top-right key just above the delete key.

Now, all that’s left to do is press the power button and wait for the boot-up chime. If your MacBook Air is not turning on, please check if your power cable is connected to the power supply or your battery is charged.
