What is D3cold?
D3 is the lowest-powered device power state, and D3cold is the lowest-powered substate of D3. Moving idle devices to the D3cold substate can reduce power consumption and extend the time that a mobile hardware platform can run on a battery charge.
What is ACPI D3cold support?
This method enables a device to idle in D3cold only if the device, the parent bus driver, and the ACPI system firmware support signaling wake events from D3cold. With few exceptions, the driver for such a device can enable the device to enter D3cold.
What is device power state?
A device power state describes the power state of a device in a computer, independently of the other devices in the computer. Device power states are named D0, D1, D2, and D3. D0 is the fully on state, and D1, D2, and D3 are low-power states.
What is device state?
The device state indicates how freely software can be flashed to a device and whether verification is enforced. Device states are LOCKED and UNLOCKED . If the device is LOCKED , the bootloader goes through the steps in Verifying Boot to verify the device’s software.

What is S3 power state?
System power state S3 is a sleeping state with the following characteristics: Power consumption. Less consumption than in state S2. Processor is off and some chips on the motherboard also might be off. Software resumption.
What is D3 state?
Device Power State D3. D3 is the lowest-powered device low-power state. All devices must support this state. Starting with Windows 8, the operating system subdivides D3 into two separate and distinct substates, D3hot and D3cold. Earlier versions of Windows define the D3 state, but not the D3hot and D3cold substates.
What is Palo Alto device state?
Palo Alto Networks XML API uses standard HTTP requests to send and receive data, allowing access to several types of data on the device. The data can then easily be integrated with and used in other systems. Using XML API you can also export the device state, which is used to backup a Palo Alto Networks firewall.
