System Manager”
Auxiliary Power
Ability to detect the presence of an external auxiliary power source.
Circuitry automatically chooses aux power, defers discharge until aux
power is removed or exhausted. Auxpower increases the DRT ratings
Battery Life and Data Retention Time
The Intel utilities display a counter showing the number of times a BBU has been recharged. When
you replace a BBU, you should run the utility program and reset this counter to zero for the new
BBU. Intel recommends that you replace the battery pack on the BBU once a year or after 500
recharging cycles, whichever comes first. The warranty on the battery pack is for one year.
The data retention time is 72 hours (low power) if using the RAM shown below. This rating is
approximate and can vary based on battery load, ambient temperature, and number of discharge
cycles associated with the battery.
