Abstract

A system requests power delivery data from an information handling system docked to a docking station, and receives a response that includes the power delivery data. If the information handling system is not in a working power state, then the system generates an image associated with the power delivery data.

First claim

What is claimed is:

1 . A method comprising:
requesting, by a processor of a docking station, power delivery data from an information handling system, wherein the information handling system is docked at the docking station, wherein the information handling system includes a lid, and wherein the docking station is connected to a display device that is separate from the information handling system; receiving a battery status data object from the information handling system in response to the requesting of the power delivery data, wherein the battery status data object includes the power delivery data that further includes a battery charge level and a system power state; if the information handling system is not in a working power state based on the system power state included in the battery status data object and the lid of the information handling system is closed, then generating an image based on the battery charge level included in the battery status data object; and displaying the generated image on the display device.

2 . The method of claim 1 , wherein the request is transmitted via a low-level transport protocol.

3 . The method of claim 1 , wherein the information handling system is in a low power state.

4 . The method of claim 1 , further comprising cloning the generated image and displaying the cloned image in another display device connected to the docking station.

5 . The method of claim 1 , wherein the generated image is a graphical icon.

6 . The method of claim 1 , wherein the information handling system is in a powered off state.

7 . The method of claim 1 , further comprising waking the display device prior to the displaying of the image.

8 . The method of claim 1 , wherein the image is a bitmap.

9 . A system, comprising:
an information handling system; and a docking station comprising a processor programmed with instructions that when executed cause the processor to perform operations including: requesting by the docking station, power delivery data from the information handling system, wherein the information handling system is docked at the docking station, wherein the information handling system includes a lid, and wherein the docking station is connected to a display device that is separate from the information handling system; receiving a battery status data object from the information handling system in response to the requesting of the power delivery data, wherein the battery status data object includes the power delivery data that further includes a battery charge level and a system power state; if the information handling system is not in a working power state based on the system power state included in the battery status data object and the lid of the information handling system is closed, then generating an image based on the battery charge level included in the battery status data object; and displaying the generated image on the display device.

10 . The system of claim 9 , wherein the information handling system is in a low-power state.

11 . The of claim 9 , wherein the operations further include cloning the generated image and displaying the cloned image in another display device connected to the docking station.

12 . The system of claim 9 , wherein the generated image is a graphical icon.

13 . The system of claim 9 , wherein the information handling system is in a powered off state.

14 . The system of claim 9 , further comprising waking the display device prior to the displaying of the image.

15 . A non-transitory computer-readable medium including instructions that are executable to perform operations comprising:
requesting, by a docking station, power delivery data from an information handling system, wherein the information handling system is docked at the docking station, wherein the information handling system includes a lid, and wherein the docking station is connected to a display device that is separate from the information handling system; receiving a battery status data object from the information handling system in response to the requesting of the power delivery data, wherein the battery status data object includes the power delivery data that further includes a battery charge level and a system power state; if the information handling system is not in a working power state based on the system power state included in the battery status data object and the lid of the information handling system is closed, then generating an image based on the battery charge level included in the battery status data object; and displaying the generated image on an external display device.

16 . The non-transitory computer-readable medium of claim 15 , wherein the information handling system is in a low power state.

17 . The non-transitory computer-readable medium of claim 15 , wherein the operations further comprise cloning the generated image and displaying the cloned image in another display device connected to the docking station.

18 . The non-transitory computer-readable medium of claim 15 , wherein the generated image is a graphical icon.

19 . The non-transitory computer-readable medium of claim 15 , wherein the information handling system is in a powered off state.

20 . The non-transitory computer-readable medium of claim 15 , wherein the operations further comprise waking the display device prior to the displaying of the image.
