Fully shut down your Mac mini and unplug all cables from it.
Flip over your Mac mini and place it on a clean, flat surface to avoid scratching the chassis.

Continue sliding and prying with the pick along the perimeter of the bottom cover to release the remaining clips.
Don't insert the pick more than an inch when sliding near the power button, as you risk damaging the cable.
During reassembly, press along the perimeter of the bottom until you hear and feel all four clips click back into place.

Don't remove the bottom cover, as it's still connected to the Mac mini with a cable.
Lift the edge of the bottom cover opposite the power button and flip it over to expose the power button cable.

The power button cable is very fragile! You don't have to disconnect it to access the internals— but it will require you to keep the bottom cover propped up.
To disconnect the cable and remove the bottom cover, follow the next two steps.
If you don't disconnect the cable, prop up the bottom cover to prevent straining the cable and skip the next two steps.
Grip the power button cable close to the head and pull it away from its socket to disconnect it.

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
While the Mac mini uses Torx Plus screws, standard Torx bits work. Make sure to apply constant, downward force to prevent stripping.
Use a Torx Plus 3IP screwdriver to remove the two 2.1 mm‑long screws securing the CMOS battery screws.

Use the flat end of a spudger, or your fingernail, to lift the CMOS battery out of its housing.
During reassembly, place the flat, shinier side of the battery into the section of the housing with the plus sign.
