Test Power transition [S3 AND S4] supported for a device

Note  This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.

Type: Automated Test


This test is not required to get a logo (see details in "Running the Test" below). This test takes the VID\PID for a device, a power state, and a number of iterations as command line parameter.

Using DevED, it finds the device and disables it. It then puts the system into the specified power state,

sets back to S0 power state, and enables the device. It validates whether the device is reenabled or not.
