ABSTRACT:
A fast resume of a computer from a low power mode to a normal operating mode captures a power down message from the operating system of the computer to devices connected thereto. In response to the captured message, the device manager is instructed to remove the device from the operating system. The computer is powered down with the device removed. The system is later powered up with the device removed, allowing for faster resume to normal operation. After the computer has returned to normal operation, the device manager reinstates the removed device. The program to capture the power down message can be above the device driver in the driver stock or be an application running in the user mode of the operating system.
