As you have asked about the steps to reset the System Management
Controller (SMC) on your Mac Book Air (MBA), I am giving you information
about it, check below for the details

First determine whether the battery is removable. Mac notebook computers
that have a non removable battery include MacBook Pro (Early 2009) and
later, all models of MacBook Air, MacBook (Late 2009), and MacBook (Retina,
12-inch, Early 2015)


If the battery is nonremovable

Shut down the Mac.
Plug in the MagSafe or USB-C power adapter to a power source and to
your Mac.

Using the built-in keyboard, press Shift-Control-Option on the left side of
the keyboard, then press the power button at the same time.

Release all keys, then press the power button again to turn on your Mac


If the battery is removable

Shut down the Mac.
Disconnect the MagSafe power adapter from the Mac.

Remove the battery. (Learn about removing the battery in MacBook and
MacBook Pro computers.)

Press and hold the power button for 5 seconds.

Reconnect the battery and MagSafe power adapter.

Press the power button to turn on the Mac.


The LED on MagSafe power adapters might change states or temporarily turn off when you reset the SMC.
