macbook pro 2021 M1 Pro.

This is a macbook 14 inch. I haven’t had it for that long only about a year. It’s not broken, but i had missing keys on a previous keyboard and I tried to replace it, but I’m not sure what I did because I can’t get it to turn on now. When I plug the charger in it blinks orange. So I believe there’s an issue with the connection on the inside. It’s still in good condition. Comes with the charger and I can include the box
