CPU Utilization:Processor utilization is high
The average processor utilization during the trace was high. The system will consume less power when the average processor utilization is very low. Review processor utilization for individual processes to determine which applications and services contribute the most to total processor utilization.
Average Utilization (%) 18.42
Platform Power Management Capabilities:ACPI _PSD Object Failed Validation
There is a problem with the definition of the ACPI _PSD object on this computer. Installing the latest system firmware (BIOS) may resolve this issue.

Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

Warnings

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) 10000
Maximum Timer Period (100ns units) 156001
Platform Timer Resolution:Outstanding Timer Request
A program or service has requested a timer resolution smaller than the platform maximum timer resolution.

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 true
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true
