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:Adaptive Display Brightness is supported.
This computer enables Windows to automatically control the brightness of the integrated display.
Platform Power Management Capabilities:Processor Power Management Capabilities
Effective processor power management enables the computer to automatically balance performance and energy consumption.
