Abstract: An IHS (Information Handling System) may transition to a low-power state when the IHS is not in use. Upon detecting a wake event, such as a button being pressed, the IHS exits the low-powers state and resumes a full-power operating state. When a wake event is inadvertently triggered, the IHS may reverted to full-power operations without the user's knowledge. In order to detect false wake events, embodiments determine contextual information about the current status of the IHS, such as power status, operational status and user status, at the time of the wake event detection. If a valid wake event is detected, the operating system is notified of the wake event. If the wake event is determined to be inadvertent based on the context of the IHS, such as the IHS being in transport and/or the user not being present in proximity to the IHS, the wake event may be disregarded.
