![]() The percentage of time that is spent in the DRIPS state (DRIPS percent) is an Each SoC defines its own DRIPS state and corresponding state index. TheĭRIPS state corresponds to the lowest power state for the SoC during Modern The most important of the platform idle states is the deepest state, DRIPS. State because the time spent in this state is critical to Modern Standby battery ![]() This section covers only the lowest power platform Contact the SoC vendor to get the specific On different platforms, the numerical states might correspond to different The Platform Idle State graph shows the residency in platform idle states The default view to obtain information about Modern Standby behavior. The following paragraphs explain how to change The upper right-hand corner of the graph window. The view can be configured by using the buttons that are located at Graph, which shows the activity levels of software and hardware components.Įach graph has a table view that shows the raw data that was used to construct Time the platform spends in the various platform idle states, and the DRIPS TwoĬommonly used WPA graphs are the Platform Idle State graph, which shows how much Observing system behavior in Modern Standby and identifying problems. The graphs that are generated from the Modern Standby WPA profile are key to "Display Required" are used for screen on scenarios.Ĭommon WPA graphs for Modern Standby power management The relevant request types for Modern Standby are "System Required" and "Execution Required" power requests. The Power Requests graph shows details for all power requests that were active during this session. The Generic Events graph can show events that are triggered by networking components such as WCM, DHCP, and TCPIP. The Device Dstate graph shows information about the activity of the Wi-Fi device. The PDC Resiliency Activity graph shows activators such as the broker infrastructure (BI) or Windows Push Notification Services (WNS) that can trigger network activities. Several graphs show networking activities. The PDC Notification Phase graph shows the details of all the PDC phases. The Device Dstate graph shows the list of Windows power framework (PoFx) devices that were active during the Modern Standby session. The CPU Idle States graph shows a list of the CPUs in the system and their respective states. The PDC Resiliency Activity graph shows a list of activators that were active during the Modern Standby session. To correlate data from a SleepStudy report to the WPA trace, use the mapping Select the graph to add and drag it to the Analysis View pane.Expand a graph category in Graph Explorer.Add other graphs to the current analysis view from Graph Explorer by.Click Browse and select the applicable profile to apply.To apply a profile, click Profiles\Apply to open a separate Analysis tab.In the WPA menu, click File, click Open, and select a trace file.Note that Wpa.exe is available for x86 and 圆4 only. Tool, install it on a computer, and follow these instructions to open the trace Use the WPA tool to view and analyze Modern Standby traces. To stop and save the trace into an event trace log (ETL), run:.While recording, put the system into Modern Standby.To start the trace, run: wpr -start Power.Open an elevated command prompt and navigate to the WPT install location.Install the Windows Performance Toolkit (WPT).Use the following method to capture a WPA trace using the Windows Performance Capture a WPA traceĬapture a trace of at least one hour of Modern Standby to observe trends and Software activity, CPU utilization, memory utilization, and other system events.Įvents that are captured in a trace show exactly what happened during Modern ![]() A traceĬontains detailed information about system platform states, device states, Observed during Modern Standby through SleepStudy or other tools. Trace capture is the key diagnostic method that is used to debug issues that are Capture and view a WPA trace for Modern Standby diagnostics The remainder of this section refers to the documents and scripts that are WPA is available in the Windows Assessment and Deployment Kit (Windows ADK)ĭownload package and includes scripts and documentation for Modern Standby For more information about the PDC Resiliency Activity graph andĭevice Dstate graph, see the " View a WPA trace" section " Common WPA graphs for connected standby power management" ![]() To spend too little time in the DRIPS state.įor more information about the Platform Idle State graph, see the Watch this video to learn how to use the Platform Idle State graph and Deviceĭstate graph to track down a hardware device that causes the hardware platform ![]()
