Device Power State Test (Compact 7)
3/12/2014
The Device Power State Test verifies if the touch panel enters sleep mode (D4 power state) and back into the fully powered on mode (D0 power state) through requests from the Power Manager. Drawing test is performed before, during and after the touch panel enters into the D4 power state. You verify by using screen prompts whether the functionality of the touch panel has been maintained during each stage. Answering 'Yes' for when the touch panel was in sleep mode is a failure as the touch panel is expected to be nonfunctional during this period.
This is test 3002 in the touchfunc.dll test suite.
NOTE: Touch panel driver level test. Requires user interaction using touch pen on the touch panel for most tests. After the test is complete, the OS loses control of the touch panel. Download a new image before running any more tests.
