Abstract
Described herein are methods and systems for switching between a normal scanning mode and a proximity detection mode for a touchscreen of an information handling system, such as a laptop or notebook personal computer. When the information handling system is in idle mode, proximity detection is enabled, by grouping sensors of the touchscreen to transmit and to received, creating an electric field. If a user's finger or pointing device enters or breaks the electric field, user presence is detected and the system switches to normal or scanning mode.
