Abstract: A computer power backup system and device are provided. When power to a computer system is lost, a battery backup unit provides power to the computer system for a while, allowing a power management control to send out an alert to an enterprise client so as to urge immediate action. If the power outage persists without being solved, and the power management control detects insufficient power in a battery of the battery backup unit, the power management control will store data in a storage device automatically and safely and then shut down the computer system. When power is restored, the power management control turns on the computer system automatically and begins charging the battery of the battery backup unit. Through the above operation, the integrity and safety of data in the computer system are secured.
