Description
In the event of a motherboard battery failure the ‘system board battery’ message is lit up on the front of the console.
CMOS (complementary metal-oxide-semiconductor) is the term usually used to describe the small amount of memory on a computer motherboard that stores the BIOS settings. Some of these BIOS settings include the system time and date as well as hardware settings.
IDRAC logs may show the message:
"The system board battery is low."
"The system board battery is operating normally."
"The system board battery is low."
"The CMOS battery is low" -

If the message persists the battery may need to be replaced.
- Open the box
