NVRAM/TOD on the replacement motherboard after installation.

To Remove the NVRAM/TOD

2. Power off the system and remove the input power connector(s).

3. Remove the top access cover.

6. Grasp the NVRAM/TOD carrier at each end and pull straight up.

Note – Gently rock the NVRAM/TOD from side to side as necessary.
