820-01521 - MacBook Air Not Booting - Restarts When Loading Internet Recovery

Hello,

I have a MacBook Air here that powers on just fine. I am able to hold D or start Internet recovery, but as soon as I connect to Wi-Fi, after 5-10 seconds of it starting, the computer restarts. The main operating system also loads to the Apple logo, stays there for 20-30 seconds and then restarts again. Customer mentioned about opening it before to change the battery. I tried new battery and still responding the same. I'd also like to add that if I hold D, it will stay in the Choose Network page indefinitely without randomly restarting. Fan spin is low / moderate.

How should I continue to troubleshoot this MacBook? Thanks!
