Random shut downs on my Mac

Hello, I have a MacBook Air M4, and I’ve been experiencing an issue where the laptop shuts down randomly — especially when I pick it up or slightly move it while it’s on. It happens even with a full battery.

I’ve already checked for macOS updates, run Apple Diagnostics, and reviewed shutdown logs, but the problem persists.

Could you please help me check whether this might be a hardware issue (like a loose battery connection or logic board problem) and guide me on repair or replacement options?
