The BIOS battery needs to be replaced, and the BIOS needs to be re-programmed. This involves removing the unit’s lid and plugging in a keyboard and monitor direct to the motherboard.
Once the lid is off, the CR2032 battery can be replaced.

Detection and Prevention
It is safe to hot-swap the CR2032 battery by lifting the lid and replacing while the unit is powered. This precludes the need to plug in a keyboard and monitor and reset BIOS configurations.
The CR2032 battery should be good for 3-5 years, so periodic maintenance every 2-3 years should suffice for routine maintenance. Schedule a unit shutdown test to verify as a part of the periodic maintenance regiment.
