Abstract

Methods, systems and computer program products for suspend profiles and hinted suspending. Exemplary embodiments include a suspend mode management method, including determining a task to perform in the computer system during a suspend period of the computer system, detecting a suspend event in the computer system, the suspend event initiating the suspend period and performing the task during the suspend period.

Claims

1. In a computer system having an input device, a suspend mode management method, comprising:

monitoring user activity of the computer system to generate a suspend profile including a plurality of prior suspend periods by tracking the plurality of prior suspend periods occurring over an extended time period;

utilizing the plurality of prior suspend periods to predict a hinted suspend event, each of the plurality of prior suspend periods being a period in which there is no user activity, the hinted suspend event indicating commencement of a period of user inactivity;

determining a task in accordance with the hinted suspend event of the suspend profile to perform in the computer system during the period of user inactivity;

dynamically detecting a current suspend event in the computer system, the current suspend event correlating to the hinted suspend event; and

in response to the detecting of the current suspend event, reading a power state of the computer system by determining a power level of a battery of the computing system and whether the computing system is plugged in;

in response to the power level being at a full power and the computing system being plugged in, performing the task during the period of user inactivity.

2. The method of claim 1, wherein the detecting of the prior suspend event in the computer system comprises:

identifying a first time in which the input device of the computer system has been engaged;

identifying a second time in which the input device of the computer system has been engaged; and

calculating a difference between the second and first times to determine the period in which there is no user activity.

3. The method as claimed in claim 1 further comprising recording a time of day in which each of the plurality of prior suspend periods occur.

4. The method as claimed in claim 3 wherein the time of day in which the user activity period occurs determines an initiation of the hinted suspend event.

5. The method of claim 4, wherein the suspend profile includes a record for each of the plurality of prior suspend periods, the period in which there is no user activity, and the hinted suspend event after it has been predicted, and

wherein each record for the user-inactivity period includes the time of day.

6. The method as claimed in claim 1 wherein the task is user-defined.

7. The method as claimed in claim 1 wherein one of the plurality of prior suspends period is user-defined.

8. The method of claim 1, further comprising:

selecting the task from a pool of deferrable work tasks;

completing the task during the period of user inactivity; and

in response to the pool of deferrable work tasks being complete, volunteering processor cycles for power management events.

9. The method as claimed in claim 1 further comprising determining a power state of the computer system to determine an appropriate workload for the computer system.

10. A computer system, comprising:

a processor;

an input device operatively coupled to the processor; and

a suspend period management process, having instructions to;

monitor user activity of the computer system to generate a suspend profile including a plurality of prior suspend periods by tracking the plurality of prior suspend periods occurring over an extended time period;

utilize the plurality of prior suspend periods to predict a hinted suspend event, wherein each of the plurality of prior suspend periods being a period in which there is no user activity, wherein the hinted suspend event indicating commencement of a period of user inactivity;

determine a task in accordance with the hinted suspend event of the suspend profile to perform in the computer system during the period of user inactivity;

dynamically detect a current suspend event in the computer system, wherein the current suspend event correlating to the hinted suspend event; and

in response to the detection of the current suspend event, read a power state of the computer system by determining a power level of a battery of the computing system and whether the computing system is plugged in;

in response to the power level determined to be at a full power and the computing system determined to be plugged in, perform the task during the period of user inactivity.

11. A computer program product for providing suspend mode management to a computer system having an input device, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor of the computer system to cause the processor to:

monitoring user activity of the computer system to generate a suspend profile including a plurality of prior suspend periods by tracking the plurality of prior suspend periods occurring over an extended time period;

utilizing the plurality of prior suspend periods to predict a hinted suspend event, each of the plurality of prior suspend periods being a period in which there is no user activity, the hinted suspend event indicating commencement of a period of user inactivity;

determining a task in accordance with the hinted suspend event of the suspend profile to perform in the computer system during the period of user inactivity;

dynamically detecting a current suspend event in the computer system, the current suspend event correlating to the hinted suspend event; and

in response to the detecting of the current suspend event, reading a power state of the computer system by determining a power level of a battery of the computing system and whether the computing system is plugged in;

in response to the power level being at a full power and the computing system being plugged in, performing the task during the period of user inactivity.

12. The computer program product of claim 11, wherein the detecting of the prior suspend event in the computer system comprises:

identifying a first time in which the input device of the computer system has been engaged;

identifying a second time in which the input device of the computer system has been engaged; and

calculating a difference between the second and first times to determine the period in which there is no user activity.

13. The computer program product as claimed in claim 12 wherein the method further comprises recording a time of day in which each of the plurality of prior suspend periods occur.

14. The computer program product as claimed in claim 13 wherein the time of day in which the user activity period occurs determines an initiation of the hinted suspend event.

15. The computer program product of claim 14, wherein the suspend profile includes a record for each of the plurality of prior suspend periods, the period in which there is no user activity, and the hinted suspend event after it has been predicted, and

wherein each record for the user-inactivity period includes the time of day.

16. The computer program product as claimed in claim 11 wherein the task is user-defined.

17. The computer program product as claimed in claim 11 wherein one of the plurality of prior suspend periods is user-defined.

18. The computer program product of claim 11, wherein the method further comprises:

selecting the task from a pool of deferrable work tasks;

completing the task during the period of user inactivity; and

in response to the pool of deferrable work tasks being complete, volunteering processor cycles for power management events.
