Resume From Connected Standby

Resume From Connected Standby is an automated test that measures latency when a machine resumes from a connected standby state.

Test details

Associated requirement(s)

System.Fundamentals.PowerManagement.CS.ResumeFromConnectedStandby

Platforms

Windows RT (ARM-based)
Windows 8 (x86)

Run time

~15 minutes

Before you run the test, complete the test setup as described in the test requirements: System Fundamentals Testing Prerequisites.

Before you run the test, make sure that no USB devices are plugged into the machine. Also ensure that the machine has wireless connectivity.

This test returns Pass or Fail. To review test details, review the test log from Windows® Hardware Certification Kit (Windows HCK) Studio.

If the test fails, run the test again with the EnableDebug flag set to 1. This adds additional debug data to the trace log.

For additional troubleshooting information, see Troubleshooting the HCK.

The test transitions the machine into and out of a connected standby state five times.

microsoft-windows-pdc-provider generates two events when resuming the machine from a connected standby state:

If the time difference between these two events exceeds 300ms for any of the iterations, the test fails.
