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 (%) 5.62
Platform Power Management Capabilities:Adaptive Display Brightness Support
This computer does not allow Windows to automatically control the brightness of the integrated display. Installing the latest system firmware (BIOS) may resolve this issue.
Platform Power Management Capabilities:ACPI _PSS Object Failed Validation
There is a problem with the definition of the ACPI _PSS object on this computer. Installing the latest system firmware (BIOS) may resolve this issue.

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
Platform Power Management Capabilities:Processor Power Management Capabilities
Effective processor power management enables the computer to automatically balance performance and energy consumption.
