PassMark Sleeper is a lightweight utility designed to test and automate a computer's ability to enter and recover from various sleep and hibernation states. It supports manual and script-driven control of sleep states (S1, S2, S3, S4), allowing users to validate and troubleshoot power management features on Windows PCs. Sleeper can be used standalone or integrated with other testing tools like PassMark BurnInTest, making it suitable for both individual troubleshooting and automated test environments.
