Question Exclamation mark sticker on motherboard after RMA ?

To me it looks like a CR2032 battery. If you look through some listing on Aliexpress, they can't ship the board to you with the battery in it. Perhaps that's what was being indicated, to remove the CMOS battery.

There's an adage, if it ain't broke, don't fix it. If the board isn't exhibiting any issues after your RMA, leave it be.

As for the screws part, never overtighten. Like Chandler once said on F.R.I.E.N.D.S, when you feel resistance, that's when you stop.
