I have a MacBook Air board A1466 here and I need help finding out what component I have circled and if it will cause the device not to turn on
Thanks:)

Could absolutely keep it from turning on. That's a Fuse. Specifically a fuse which bridges PPVBAT to PPBUS_G3H (battery power to the main system power rail). For replacement purposes it's an 8A 24V fuse in a 1206 package size. Without this fuse, power doesn't go to the system.
If it's missing, be mindful of why it's missing. Was it removed intentionally? Fuses are designed to blow to protect the system downstream, but many times blow due to an issue upstream. So this fuse may not be your only issue.

Hi
thanks for the reply it’s means a lot
The fuse was very corroded and fell of the board during a ultrasonic cleaning session
The board was very water damaged so that’s why it fell off so easy
Thanks Again
@hellomacos Yes, that makes perfect sense. Much more sense than the explanations my brain was generating. Hopefully you get get this board up and running again.
