Let me help you with this.
I would like to verify more information about the system and the issue you are having so I can have a clear picture of the issue.
Please provide the following:
- What is the computer brand and model?
- Where are you changing the power options?
- What is the name of the automation tool you mentioned?
- Was the Wireless adapter installed by you?
I'm doing internal testing with a BDW-ULT board. The tool is something one of our developers created, so it's for internal use only. I'm managing power options via Win 8.1's power options from the control panel (where you can select a power plan, and then choose advanced settings). I did install the wireless adapter.
The issue is intermittent -- I ran tests overnight and it worked fine. When it went to sleep the other day, the system event log does show an S3 event, with the cause a vague application API request, but no mention of which application.
