Power capabilities
This inventory object displays detailed information about the system power management hardware resources and capabilities of the remote device. This includes information about the presence of hardware features such as power buttons, lid switches, and batteries. Other details returned include information about current power management capabilities and configurations that can change dynamically, such as the minimum sleep state currently supported, which might change as new drivers are introduced into the system, or the presence of the system hibernation file.
The collected parameters are the following:
Parameter | Description |
|---|---|
Allows Removal of Power to fixed Disk Devices | Indicates if the system supports allowing the removal of power to fixed disk devices. |
APM BIOS Power Management Features | Indicates if the system supports APM BIOS power management features. |
Batteries Present in the System | Indicates if there are one or more batteries in the system. |
Display Brightness | Indicates if the system supports screen dimming capabilities. |
Hibernate | Indicates if the local system supports sleep state 4. In this state the system displays to be off. Power consumption is reduced to the lowest level. The system saves the contents of memory to a hibernation file, preserving the state of the operating system, applications, and open documents. |
Hibernate File Present | Indicates if the system hibernation file is present. |
Lid Switch | Indicates if a lid switch is present. This parameter is only applicable to laptops and notebooks. |
Low Power Saving | Indicates if the local system supports sleep state 1. In sleep states 1-3 the system displays to be off. Power consumption is reduced to one of several levels, depending on how the system is to be used. The lower the level of power consumption, the more time it takes the system to return to the working state. |
Maximum Power Saving | Indicates if the local system supports sleep state 3. |
Medium Power Saving | Indicates if the local system supports sleep state 2. |
Power Button | Indicates if a power button is present on the device. |
Processor Throttling | Indicates if the system supports processor throttling. |
Short-term Batteries | Indicates if the system batteries are short-term. Short-term batteries are used in uninterruptible power supplies (UPS). |
Shutdown | Indicates if the local system supports sleep state 5, that is, power off. In this state the system displays to be off. Some components remain powered so the computer can wake from input from the keyboard, LAN, or a USB device. The working context can be restored if it is stored on non-volatile media. |
Suspend Button | Indicates if a sleep button is present. |
Thermal Zones | Indicates if the system supports thermal zones. |
UPS Present | Indicates if there is an uninterruptible power supply (UPS). |
Wake Capabilities | Indicates if the system supports wake capabilities. |
