Abstract
A computer keyboard power saving method includes sensing if there is keystroke action taking place. When time period of no keystroke action exceeds a pre-set threshold, power supply to the keyboard will be shut down automatically. When a keystroke action is detected, power supply to the keyboard will be resumed instantly. Thus can save energy when keyboard is idle from time to time.
