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) 156000

System Availability Requests:Analysis Success
Analysis was successful. No energy efficiency problems were found. No information was returned.
USB Suspend:Analysis Success
Analysis was successful. No energy efficiency problems were found. No information was returned.
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 (%) 1.73
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
