1. Executive Summary Wake timers are a power management feature in Windows 11 that allow scheduled events to bring the computer out of a low-power state (Sleep, Modern Standby, or Hibernate) to perform a task. While essential for maintenance, updates, and user convenience, poorly configured wake timers can lead to unexpected battery drain, overheating in laptop bags, and disruption of power-saving strategies. wake timers windows 11
