The button is glued to the main shell. I’ll suspecting its now become detached since you can slide it under. I’ve only seen this happen one time with all of the systems I’ve fixed. You’ll need to re-apply the part as you’ll have a hard time replacing it so use care here.
Getting to the button housing is a big job as its hidden under the left speaker which means you need to pull the logic board out as well as the the CPU fan before you can even get to it.
While not impossible, its just a very big job, you might want to let someone with more experience deal with this that taking it on your self (if this is your first time). In any case plan out your space as it’s going to take a bit and you’ll need to wait till the glue dries before putting things back together.
