In order to re-seat or replace the CMOS battery on your N7 Z590 motherboard, you will need to remove the metal cover to gain access to the battery socket.  It is recommended to remove the motherboard from the PC completely before continuing, as this will make access to plates far easier.

You will need the following tools for this guide:

• A Philips #1 screwdriver (for removing the motherboard)
• A spudger or pry tool.  Nylon/plastic is recommended.

Preparing the Motherboard

Before removing the metal cover, you will need to remove the two M.2 covers as outlined below:

Releasing the Metal Plate

With the M.2 covers removed, use your pry tool t lift the metal plate at the top-right corner of the motherboard, followed by the bottom-right and bottom left as shown in the images below:

With the metal plate removed, the CMOS Battery Socket will be exposed at the center of the board.

To remove the battery, press the spring-latch outward from the center of the socket using either your pry tool or screwdriver.

To replace the battery, angle the battery under the edge of the socket and press down until the battery clicks into place.  Reverse the steps provided to re-install the metal plates.
