Einleitung

Use this guide to replace the CMOS battery in your Mac mini (2024).

This CMOS battery is a standard 3V BR1632 coin cell battery.

Was du brauchst

  1. Mac mini (2024) CMOS Battery Replacement, Before you begin: Schritt 1, Bild 1 von 2 Mac mini (2024) CMOS Battery Replacement, Before you begin: Schritt 1, Bild 2 von 2

    • 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.

    • Using the Jimmy or other metal tools during this step could scratch the aluminum chassis; however, it's the simplest way to perform this step. Follow the alternate instructions to avoid scratching the aluminum.

    • Insert a Jimmy into the gap between the bottom cover and the chassis.

    • Pry up the bottom cover to create a gap.

    • Alternatively, you can insert the point of a spudger into one of the plastic vent holes and pry up to create a gap big enough to insert an opening pick into.

    • Keep the Jimmy inserted under the bottom cover.

    • Slide the opening pick along the bottom cover until you feel it snag on a pin.

    • There are four pins total—one at each corner of the bottom cover.

    • Twist the pick to lift the pin out of its slot.

    • Continue sliding and prying with the pick along the perimeter of the bottom cover to release the remaining pins.

    • 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 pins 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.
