My MacBook Air will not power up, it charges, and I have tried all of the reboot options.

Hello luther148,

Welcome to Apple Support Communities. We'd be happy to look into this with you. What happens when you try the different keyboard combinations while starting up? Does it make any noises, or show any sign of life? Do you recall anything happening to your MacBook Air before this issue started happening like software update, physical or liquid damage?

To get started, please try the steps here:

If your Mac doesn't turn on

If your Mac starts up to an Apple logo or progress bar

If that didn't help, please reach out to Apple Support for service options. You can contact them using this link: Get Support

We hope this information is useful. Kind regards.
