Methods, systems and computer program products are provided for touch detection of computing device position. A touch filter monitor signals generated by one or more touch input devices for a signature of one or more other input devices proximate to the touch input device, which may indicate a user physically manipulated the computing device to render the input device(s) inoperable, such as by closing a portable computer. The touch filter controls the computing device to enter or remain in a power saving mode based on detection of one or more signatures of one or more other input devices in a signal generated by the monitored touch input device(s).
