Issue

  • During the battery learning cycle, the system shut down because of the IPMI sensors detected several battery errors.

  • According to the environment sensors,
    • the Bat Learning Active status is still ON, and many statuses have failed. 
    • The Bat Pct Capacity is critlow. 
    • The battery charge has failed, and the Dblade Temp is OVER_TEMP.
