Any Idea Where This Goes?

Hey everyone,

possible

I took apart my nephews PS4 model CUH-1215A since it would turn on and turn right back off. I replaced the power cable and viola it started and stayed on just fine but while putting it all back together I was left with this clip stamped F2 and have done every possible google search and have come up with no answer as to where it’s supposed to go. I would hate leaving it out then have my nephew come back saying something went wrong with it.

Anyone have any idea? Thanks for the help in advance!
