PowerLockGuard is a specialized power management and process watchdog utility designed for Windows systems. The program addresses a specific operational problem: unattended overnight computational workloads. It serves developers, artificial intelligence agent runners, data scientists, and laptop users who initiate long-running tasks such as model training, software compilation, or autonomous agent execution. The core mechanism involves a Work Watchdog component that monitors developer process telemetry in real time. It identifies active work by tracking CPU utilization of known processes. When activity falls below configurable thresholds for a set duration, the program initiates a clean suspend or shutdown sequence. A separate Charger Guard module provides blackout protection. If the power adapter is unplugged, this module triggers an immediate S3 Deep Sleep state within milliseconds. This action preserves the active RAM state, including in-progress AI tasks and unsaved data, preventing corruption and token waste before network timeout exceptions occur.
