ABSTRACT:
Systems and methods are delineated for selectively enabling input from a touch pad in electronic equipment, such as a personal computer, to prevent unintended user input from the touch pad. The electronic equipment may include a keyboard unit and an embedded controller (EC). The keyboard unit may include a special key for generating an interrupt to the EC. An event utility may judge a factor related to the interrupt. If the factor is intended to control the permission or prohibition to use the touch pad, the event utility sends an instruction to the EC for respectively switching the touch pad to an enable state or to a disable state in accordance with the usage permission or prohibition.
