Shuts down on its own

Hi,

If your MacBook Air has intel processor, resetting SMC could solve the issue.

How to reset the SMC of your Mac - Apple Support

Troubleshoot Mac Volume:

What to Try:

• Raise the Volume: If sound is not working, then raise the volume.

• Remove External Devices: Verify what your output item is. Also, disable Bluetooth, if enabled.

• Go Here: If the Internal Speakers on your Mac aren't Working - Apple Support

• Boot into Safe Mode:

When you boot into Safe Mode, items load by default, with certain settings and caches set aside. So, hold down the shift key upon boot. See what happens then.

• Create a New Administrator:

See if creating and logging in as a new administrator does the trick. There may be something misconfigured in your current user - something that is getting in the way. Go to: System Preferences > Users & Groups > Unlock > Click: "+" > Create the new administrator

I tried the reset process. No change. If I close the laptop plugged in or not, it shuts down and must be restarted and logged in on opening.
