An apparatus for dynamically managing the power consumption of peripheral devices in a computer includes at least one peripheral device, a power management unit, and a memory unit. The power management unit includes a daemon program and a device idle time table. The daemon program is used for carrying out a first criterion by determining whether the power supplied to the device is associated with an active application program of the computer based on the device idle time table, and carrying out a second criterion by determining whether the power supplied to the device is associated with the inactive application programs of the computer based on the device idle time table. A power-saving signal is sent to an operating system of the computer when both criteria are satisfied, and the operating system activates an embedded power management utility to turn off the peripheral device in response to the power-saving signal.

Windows-driven power management for peripheral devices in a computer system

Disclosed is a windows-based power management method for optimally distributing power for various tasks in a portable device. The power management method includes the following steps: (a) categorizing each task to be executed by the portable device, (b) prescribing a power management policy, (c) distributing shares of a power supply unit among the tasks based on the category the tasks are associated therewith according to the power management policy, and (d) in response to the commands input by the user through a graphical user interface, increasing the share of the power supply unit provided for a task running within an active window of the portable device to accomplish an optimized distribution of power among tasks to be executed by the portable device.

Windows-based power management method and related portable device

The present invention discloses a server automatically detecting a new joining portable device in a wireless local area network (LAN) and providing the new joining portable device with a new identification number, thereby the portable device can automatically access the wireless LAN and obtain the services from the server.
