Abstract

Hibernating a computing system. The method includes detecting at least one condition which indicates the availability of time to perform hibernation optimization steps on the computing system. The hibernation optimization steps optimize resume time from hibernate. The method further includes detecting a trigger indicating that the computing system is to be put into a hibernate state. As a result of detecting the at least one condition and the trigger, the method further includes performing hibernation steps to hibernate the computing system in a way that optimizes resume time from hibernate of the computing system.

First claim

What is claimed is:

1. A computing system comprising:
a memory;
one or more processors; and
one or more non-volatile computer-readable media having stored thereon instructions that are executable by the one or more processors to configure the computing system to hibernate, including instructions that are executable to configure the computing system to:
detect that the non-volatile computer-readable media have no penalty for disk seeks such that random non-contiguous I/O operations have the same relative cost as contiguous I/O operations, wherein the non-volatile computer-readable media comprises a page file and a hibernate file;
detect a trigger indicating that the computing system is to be put into a hibernate state; and
as a result of detecting that the computing system comprises non-volatile computer-readable media with no penalty for disk seeks and the trigger, perform hibernation to hibernate the computing system in a way that reduces a resume time of the computing system from hibernate from an anticipated resume time, wherein to reduce the resume time is performed by selecting a portion of memory content in the memory to be stored in the page file instead of the hibernate file.

2. The computing system of claim 1 , wherein to perform hibernation comprises:
during performing hibernation, flushing state information from the memory at the computing system to the page file in a virtual memory on the non-volatile computer-readable media of the computing system; and
storing only a portion of the state information in the hibernate file to implement a user interface on restore from hibernate.

3. The computing system of claim 1 , wherein the one or more non-volatile computer-readable media include additional instructions executable by the one or more processors to cause the computing system to detect that a user is not present at the computing system, and to perform hibernation in response to detecting that the user is not present at the computing system.

4. The computing system of claim 3 , wherein to detect that the user is not present at the computing system comprises to detect that the user is not present at the computing system using a camera.

5. The computing system of claim 3 , wherein to detect that the user is not present at the computing system comprises to detect that the user is using a different device than the computing system.

6. The computing system of claim 3 , wherein to detect that the user is not present at the computing system comprises to detect that the user's calendar indicates that user has an appointment that prevents the user from being present at the computing system.

7. The computing system of claim 1 , wherein to detect the trigger comprises to determine that a user has moved away from the computing system.

8. The computing system of claim 2 , wherein the one or more non-volatile computer-readable media further have stored thereon instructions that are executable by the one or more processors to cause the computing system to:
determine whether writing the page file can be performed within a predetermined threshold of writing the hibernate file; and
wherein to perform hibernation includes to perform hibernation in response to determining that writing the page file can be performed within the predetermined threshold of writing the hibernate file.

9. The computing system of claim 1 , wherein the one or more computer-readable media further have stored thereon instructions that are executable by the one or more processors to cause the computing system to:
detect an amount of time for performing hibernation; and
wherein to perform hibernation includes to perform hibernation within the detected amount of time.

10. A computer implemented method of hibernating a computing system, the method comprising:
detecting that the computing system comprises one or more non-volatile storage media with no penalty for disk seeks such that random non-contiguous I/O operations have the same relative cost as contiguous I/O operations, wherein the non-volatile storage media comprises a page file and a hibernate file;
detecting a trigger indicating that the computing system is to be put into a hibernate state; and
in response to detecting that the computing system comprises the non-volatile storage media with no penalty for disk seeks and the trigger, performing hibernation to hibernate the computing system to reduce a resume time of the computing system from hibernate from an anticipated resume time, wherein to reduce the resume time is performed by selecting a portion of memory content in the memory to be stored in the page file instead of the hibernate file.

11. The method of claim 10 , wherein performing hibernation comprises:
during performing hibernation, flushing state information from the memory at the computing system to the page file in a virtual memory on the non-volatile storage media of the computing system; and
storing only a portion of the state information in the hibernate file to implement a user interface on restore from hibernate.

12. The method of claim 10 , further comprising detecting that a user is not present at the computing system, and wherein performing hibernation includes performing hibernation in response to detecting that the user is not present at the computing system.

13. The method of claim 12 , wherein detecting that the user is not present at the computing system comprises detecting that the user is not present at the computing system using a camera.

14. The method of claim 12 , wherein detecting that the user is not present at the computing system comprises detecting that the user is using a different device.

15. The method of claim 12 , wherein detecting that the user is not present at the computing system comprises detecting that the user's calendar indicates that user has an appointment that prevents the user from being present at the computing system.

16. The method of claim 10 , wherein detecting the trigger comprises determining that a user has moved away from the computing system.

17. The method of claim 10 , further comprising:
detecting that the one or more non-volatile storage media have read speeds meeting a predetermined threshold;
wherein performing hibernation includes performing hibernation in response to detecting that the one or more non-volatile storage media have read speeds meeting the predetermined threshold.

18. The method of claim 10 , further comprising:
detecting an amount of time for performing hibernation; and
wherein performing hibernation includes performing hibernation within the detected amount of time.

19. A computer implemented method of hibernating a computing system having a memory, one or more non-volatile storage media, and one or more processors operatively coupled to one another, the method comprising:
detecting that the one or more non-volatile storage media have no penalty for disk seeks such that random non-contiguous input/output operations have same relative cost as contiguous I/O operations on the one or more non-volatile storage media, wherein the non-volatile storage media comprises a page file and a hibernate file;
detecting a trigger indicating that the computing system is to be put into a hibernate state;
in response to detecting that the one or more non-volatile storage media have no penalty for disk seeks and the trigger, performing hibernation operations to put the computing system in the hibernate state; and
during performing the hibernation operations, selecting a portion of memory content in the memory to be stored in
