How to Reset the Vault’s CMOS/BIOS

Print

The Vault’s CMOS is a small amount of battery backed memory that retains system information and settings that are used by the BIOS. The CMOS can occasionally get into a state where it needs to be reset in order to address odd behavior. ¬†This can occur due to an improper shutdown (see this FAQ) or other reasons. Symptoms of odd behavior on the Vault include:

  • Video output that is black, despite power being applied to the unit
  • Odd Performance issues
  • BIOS lockouts (setting and forgetting the BIOS Administrator or User Password)
  • Boot directly to BIOS without the Vault being able to recognize any connected drives
  • Other odd behavior

Resetting the CMOS restores the BIOS to the default settings and can sometimes resolve these types of issues.
