Apple MacBook Air 13″ Boot Loop & WiFi Not Detected
An excellent condition MacBook Air 13″ 2017 model all of a sudden will not start anymore. When powered on a white Apple logo will come up then reboot, continuously with the Apple chime sound repeating.
Client also reported WiFi sometimes comes and goes. We suspect this is an actual fault with the unit and nothing the user did to cause.
It wasn’t difficult for us to fix this issue with the right tools. We managed to re-flash the BIOS chip, fix a power controller managing the WiFi chip and also found another controller chip managing overall power of the logic board when turned on, all repaired and ready to go for the client in 2 business days.
