We have released a new program today. Sleeper

Sleeper is a small utility program developed by PassMark Software to help test the ability of PC systems to enter and recover from sleep and hibernation. It has been designed to work with PassMark BurnInTest http://www.passmark.com/products/bit.htm but will also work with 3rd party applications. Sleeper allows you to,
  • Put a PC into any sleep state (S1, S2, S3) supported by the system
    Place your PC into hibernation (S4)
    Wake the computer after a specified period of time.
    Put a PC to sleep or hibernation from the command line
    Force the PC into the requested sleep state
    Cycle through all sleep states or just all states supported by the system
    Launch Sleeper from BurnInTest scripts to test sleep states between test runs.
    Display the supported sleep states


The utility is free and available here,
