Abstract

An information handling system includes a primary integrated display platform and a secondary integrated display platform attached via a hinge, and including a passive cooling system, a dynamic thermal management system, and a processor. The information handling system further includes an application window locator system for determining a location of a software application display window running on the information handling system on the primary integrated display platform or the secondary integrated display platform.

First claim

What is claimed is:

1. An information handling system comprising:
a primary integrated display platform and a secondary integrated display platform attached via a hinge;
a passive cooling system;
a processor executing instructions for a dynamic thermal management system to determine a thermal profile of the information handling system relative to a thermal threshold level;
the processor determining a first relative orientation of the first integrated display platform to the secondary integrated display platform from a plurality of orientation sensors; and
the processor operationally limiting a portion of the information handling system according to a thermal management policy based on the first relative orientation of the first integrated display platform to the secondary integrated display platform when the thermal profile of the information handling system reaches the thermal threshold level associated with the first relative orientation.

2. The system of claim 1 , wherein a designation of the primary integrated display platform and the secondary integrated display platform is switchable as to which integrated display platform is designated as primary.

3. The system of claim 1 , further comprising:
a flexible display including a first portion proximate to the primary integrated display platform and a second portion proximate to the secondary integrated display platform.

4. The system of claim 1 , further comprising:
the processor to determine determining an operating state rank of a first software application relative to a second software application; and
the processor to operationally limit a portion of the information handling system according to a thermal management policy by operationally limiting execution of a software application having a lower operating state rank when a thermal threshold level is reached.

5. The system of claim 4 , wherein operationally limiting a portion of the information handling system includes suspend the software application having the lower priority operating state rank if the thermal profile reaches a second thermal threshold level.

6. The system of claim 1 , wherein operationally limiting a portion of the information handling system includes reducing power to a portion of the display device at the secondary integrated display platform.

7. The system of claim 1 , wherein operationally limiting a portion of the information handling system includes reducing the refresh rate of a display portion of the secondary integrated display platform.

8. The system of claim 1 , further comprising:
the processor to determine individual thermal profiles for each of the primary integrated display platform and the secondary integrated display platform in the information handling system.

9. The system of claim 1 , further comprising:
the processor decreases the thermal profile threshold level in accordance with lessened thermal dissipation associated with the first relative orientation.

10. A computer-implemented method for dynamic thermal management of an information handling system having a passive cooling system and a first integrated display platform hinged to a secondary integrated display platform, comprising:
determining, via a processor executing instructions, a thermal profile of the information handling system relative to a thermal threshold level;
determining a first relative orientation of the first integrated display platform to the secondary integrated display platform from a plurality of orientation sensors; and
operationally limiting a portion of the information handling system according to a thermal management policy based on the first relative orientation of the first integrated display platform to the secondary integrated display platform when the thermal profile of the information handling system reaches the thermal threshold level associated with the first relative orientation.

11. The method of claim 10 , wherein first relative orientation is selected from a plurality of orientation modes including at least a laptop mode, a book mode, and a double tablet mode.

12. The method of claim 10 , further comprising:
determining the thermal threshold level based on the first relative orientation of the first integrated display platform to the secondary integrated display platform.

13. The method of claim 10 , further comprising:
determining an operating state rank of a first software application relative to a second software application; and
operationally limiting execution of a software application having a lower operating state rank when a thermal threshold level is reached.

14. The method of claim 10 , further comprising:
determining an operating state rank of a first software application relative to a second software application; and
suspending the software application having the lower priority operating state rank when a thermal threshold level is reached.

15. The method of claim 10 , wherein operationally limiting a portion of the information handling system includes reducing refresh rate on the first or second integrated display platform.

16. The method of claim 10 , further comprising:
changing the thermal profile threshold level in accordance with improved or lessened thermal dissipation associated with the first relative orientation.

17. An information handling system comprising:
a primary integrated display platform and a secondary integrated display platform attached via a hinge;
a passive cooling system;
a processor executing instructions for a dynamic thermal management system to determine a thermal profile of the information handling system relative to a thermal threshold level;
the processor determining a first relative orientation of the first integrated display platform to the secondary integrated display platform from a plurality of orientation sensors; and
the processor operationally limiting execution of at least one software application according to a thermal management policy based on the first relative orientation of the first integrated display platform to the secondary integrated display platform when the thermal profile of the information handling system reaches the thermal threshold level associated with the first relative orientation.

18. The system of claim 17 , further comprising:
a camera integrated in the information handling system to detecting a viewer location and further determine the first relative orientation of the first integrated display platform to the secondary integrated display platform.

19. The system of claim 17 , wherein processor operationally limiting execution of at least one software application according to a thermal management policy further determines to suspend the software application having the lower priority operating state rank if the thermal profile reaches a second thermal threshold level.

20. The system of claim 17 , wherein the dynamic thermal management system further determines to reduce the power to a portion of a display device proximate to the secondary integrated display platform.
