1. A system, comprising:
- an external peripheral device configured to be powered by a power source and being connected to at least one uninterrupted power supply (UPS) configured to supply power to the external peripheral device if the power source fails;
a computer system configured to execute at least one operating system instance that functions with the external peripheral device;
an uninterrupted power supply (UPS) management logic configured to determine a power status of the external peripheral device based on signals from the UPS; and
the UPS management logic being configured to transmit a power loss notice, based on the power status, to the operating system instance that causes the operating system instance to shut down operation of the external peripheral device while allowing the computer system to continue operating.

10. A power management product for a computer system, the product comprising:
-
logic configured to maintain system configuration data in a data store that describes associations between external devices, uninterrupted power supplies, and operating system instances, where an external device is powered by a power source and is connected to the computer system, where an uninterrupted power supply is configured to provide backup power to a selected external device, and where an operating system instance is configured to control the selected external device;
a management logic configured to receive a power loss signal from the uninterrupted power supplies that indicates at least an expiration of backup power;
the management logic further including logic configured to use the system configuration data from the data store to (1) identify a selected external device that is powered by the uninterrupted power supply that transmitted the power loss signal, and (2) identify an operating system instance that controls the selected external device; and
a notice logic being configured to transmit a device shutdown notice to the identified operating system instance that indicates an upcoming total power loss for the selected external device, the device shutdown notice being configured to cause the identified operating system instance to shutdown the selected external device. - View Dependent Claims (11, 12)

13. In a computer system that comprises at least one operating system instance configured to control an external device, where the external peripheral device is configured to be powered by a power source and includes at least one uninterrupted power supply (UPS) for providing a backup power, a method comprising:
-
notifying the at least one operating system instance of an upcoming total power loss for the external device; and
performing a shutdown of the external device before the upcoming total power loss so that data can be saved and the at least one operating system instance can continue operation without the external device. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system, comprising:
-
means for determining a power status of one or more power sources that power one or more external input/output devices connected to a computer system;
means for notifying an operating system before a power loss occurs based on the power status that causes the operating system to shut down a selected external input/output device and allow the computer system to continue functioning; and
means for notifying the operating system, based on the power status, when power is restored to the selected external input/output device to cause the operating system to re-establish operation of the selected external input/output device.

20. A set of application programming interfaces embodied on a computer-readable medium for execution by a computer component in conjunction with an uninterrupted power supply (UPS) management system, the application programming interfaces comprising:
-
a first interface for allowing a user to access the UPS management system and configure UPS system configuration data, where the UPS management system is configured to maintain, in a data store, the UPS system configuration data relating to UPS devices and associations to external I/O devices that are connected to a computer system; and
a second interface for causing a computer to modify the contents of the data store based on the UPS system configuration data configured by the user.
