Secure wake-on of a computing device
In some examples, an embedded controller of a computing device may detect, when the computing device is in a low-power state, that a smartcard has been connected to a port of the computing device or that data has been received from an input device (e.g., keyboard or biometric input device) connected to the computing device.
