Abstract

In one or more embodiments, a wireless communications device of an information handling system may receive wireless power from a wireless charging unit, coupled to a wireless docking device; in response to receiving the wireless power from the wireless charging unit, the wireless communications device of the information handling system may establish wireless communications with a wireless communications device of the wireless charging unit; the wireless communications device of the information handling system may wirelessly receive information from the wireless communications device of the wireless charging unit; the wireless communications device of the information handling system may provide the information to an embedded controller of the information handling system; and the embedded controller may perform an action associated with the information handling system. In one or more embodiments, the information may include a state transition command configured to transition the information handling system to an information processing state.

Claims (44)

1. An information handling system, comprising:

a first processor;

a first non-volatile memory medium, coupled to the first processor, that stores instructions executable by the first processor;

a volatile memory medium coupled to the first processor;

a wireless power receiver;

a microcontroller coupled to the first processor;

a wireless communications device coupled to the wireless power receiver and coupled to the microcontroller; and

a power supply configured to provide power to components of the information handling system;

wherein the microcontroller includes a second processor and a second non-volatile memory medium, which stores instructions executable by the second processor;

wherein the information handling system is configured to utilize an information processing state and a hibernate state, wherein, in the hibernate state, the first processor does not execute the instructions and the volatile memory medium was flushed to the non-volatile memory medium;

wherein the wireless power receiver is configured to receive power via one or more magnetic fields of a wireless charging unit and is configured to provide power to the wireless communications device from the one or more magnetic fields;

wherein, while the information handling system is in the hibernate state, the wireless communications device is configured to:

draw power from the wireless power receiver without drawing power from the power supply;

wirelessly communicate with another wireless communications device of the wireless charging unit;

wirelessly receive a state transition command from the other wireless communication device of the wireless charging unit; and

provide the state transition command to the microcontroller;

wherein, while the information handling system is in the hibernate state, the microcontroller is configured to operate independently of the first processor to:

receive the state transition command from the wireless communications device; and

transition the information handling system from the hibernate state to the information processing state in response to the state transition command, wherein in the information processing state, the first processor executes instructions; and

wherein the information handling system is configured to restore, from the first non-volatile memory medium, the volatile memory medium that was flushed to the first non-volatile memory medium, in response to being transitioned from the hibernate state to the information processing state.

2. The information handling system of claim 1 ,

wherein the instructions include an operating system; and

wherein the information handling system is configured to boot the operating system from the first non-volatile memory medium in response to being transitioned from the hibernate state to the information processing state.

3. The information handling system of claim 1 ,

wherein the wireless communications device includes a first Bluetooth communications device; and

wherein the other wireless communications device includes a second Bluetooth communications device, different from the first Bluetooth communications device.

4. The information handling system of claim 1 , wherein microcontroller includes an integrated circuit that includes the second processor and the second non-volatile memory medium.

5. A method, comprising:

an information handling system transitioning to a hibernate state, wherein, in the hibernate state, a first processor of the information handling system does not execute instructions, wherein the information handling system includes the first processor and a first non-volatile memory medium, which stores instructions executable by the first processor; and

while the information handling system is in the hibernate state:

a wireless communications device of the information handling system receiving wireless power from a wireless charging unit, coupled to a wireless docking device, wherein the wireless communications device of the information handling system draws power from the wireless charging unit without drawing power from a power supply of the information handling system;

in response to the wireless communications device of the information handling system receiving the wireless power from the wireless charging unit, the wireless communications device of the information handling system establishing wireless communications with a wireless communications device of the wireless charging unit;

the wireless communications device of the information handling system wirelessly receiving a state transition command from the wireless communications device of the wireless charging unit;

the wireless communications device of the information handling system providing the a state transition command to a microcontroller of the information handling system, wherein the microcontroller includes a second processor and a second non-volatile memory medium, which stores instructions executable by the second processor;

the microcontroller receiving, independently of the first processor, the state transition command from the wireless communications device; and

the microcontroller transitioning, independently of the first processor, the information handling system from the hibernate state to an information processing state in response to the state transition command, wherein in the information processing state, the first processor executes the instructions; and

in response to being transitioned from the hibernate state to the information processing state, the information handling system restoring, from the first non-volatile memory medium, a volatile memory medium of the information handling system that was flushed to the first non-volatile memory medium.

6. The method of claim 5 , further comprising:

in response to being transitioned from the hibernate state to the information processing state, the information handling system booting an operating system from the first non-volatile memory medium.

7. The method of claim 5 , wherein a wireless docking system includes the wireless charging unit and the wireless docking device.

8. The method of claim 5 ,

wherein the wireless communications device of the information handling system includes a first Bluetooth communications device; and

wherein the wireless communications device of the wireless charging unit includes a second Bluetooth communications device, different from the first Bluetooth communications device.

9. The method of claim 5 , wherein microcontroller includes an integrated circuit that includes the second processor and the non-volatile memory medium.
