Information

Platform Timer Resolution:Platform Timer Resolution
The default platform timer resolution is 15.6ms (15625000ns) and should be used whenever the system is idle. If the timer resolution is increased, processor power management technologies may not be effective. The timer resolution may be increased due to multimedia playback or graphical animations.
Current Timer Resolution (100ns units) 156262
Power Policy:Active Power Plan
The current power plan in use
Plan Name OEM Balanced
Plan GUID {381b4222-f694-41f0-9685-ff5bb260df2e}
Power Policy:Power Plan Personality (Plugged In)
The personality of the current power plan when the system is plugged in.
Personality Balanced
Power Policy:802.11 Radio Power Policy is Maximum Performance (Plugged In)
The current power policy for 802.11-compatible wireless network adapters is not configured to use low-power modes.
Power Policy:Video quality (Plugged In)
Enables Windows Media Player to optimize for quality or power savings when playing video.
Quality Mode Optimize for Video Quality
CPU Utilization:Processor utilization is low
The average processor utilization during the trace was very low. The system will consume less power when the average processor utilization is very low.
Average Utilization (%) 0.24
Battery:Analysis Success
Analysis was successful. No energy efficiency problems were found. No information was returned.
Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported false
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true
Platform Power Management Capabilities:Connected Standby Support
Connected standby allows the computer to enter a low-power mode in which it is always on and connected. If supported, connected standby is used instead of system sleep states.
Connected Standby Supported false
Platform Power Management Capabilities:Processor Power Management Capabilities
Effective processor power management enables the computer to automatically balance performance and energy consumption.
