Abstract:
Prior art attempts to reduce the power consumption demands of dual infrared transceiver laptop computer designs have. included enabling and disabling infrared ports at the user level. This solution requires the computer user to be involved in decision making with respect to infrared peripheral device discovery, and adds complexity to the overall infrared communications experience. Post connection dual IrDA port power management implements the infrared transceiver power down decision making in software, based upon activity inputs from the infrared link controller. Minor changes to the link controller at its device driver improve the user experience and the power consumption in dual IrDA port configurations.
