Abstract

Example embodiments disclosed herein relate to reporting a first updated threshold level related to a battery. A parameter related to power to be drawn by the computing device for the first OS to enter a hibernate state is monitored. The first updated threshold level are set based on the parameter. The first updated threshold level is reported to the first OS. The first OS is to vary the first battery level threshold based on the first updated threshold level.

Claims

1. A method, comprising:

determining, by a computing device, a minimum battery level to transition the computing device to a reduced power state;

determining, by the computing device, a modified remaining battery capacity based on the minimum battery level and an actual remaining battery capacity of a battery powering the computing device; and

reporting the modified remaining battery capacity in place of the actual remaining battery capacity.

2. The method of claim 1, wherein the reduced power state is a hibernate state, and wherein determining the modified remaining battery capacity comprises determining a reserve level of the battery that is sufficient to power the computing device to enter and wake from a sleep state before entering the hibernate state.

3. The method of claim 1, further comprising:

monitoring a parameter varying with operation of the computing device; and

determining the minimum battery level based on the monitored parameter.

4. The method of claim 3, wherein the monitored parameter comprises an amount of information from a memory to be saved.

5. The method of claim 4, wherein the monitored parameter comprises priorities of redundant and non-redundant types of the information to be saved.

6. The method of claim 3, wherein the monitored parameter comprises at least one of an age, power capacity and number of refresh cycles of the battery.

7. The method of claim 3, wherein the monitored parameter comprises at least one of a temperature, processing speed, and power utilization of a component of the computing device.

8. The method of claim 1, further comprising:

determining the actual remaining battery capacity using at least one of coulomb counting and voltage detection.

9. A computing device, comprising:

a hardware processor; and

a machine-readable storage medium storing instructions, the instructions executable by the hardware processor to;

determine a minimum battery level to transition the computing device to a reduced power state;

determine a modified remaining battery capacity based on the minimum battery level and an actual remaining battery capacity of a battery powering the computing device; and

report, to an operating system of the computing device, the modified remaining battery capacity in place of the actual remaining battery capacity.

10. The computing device of claim 9, wherein the reduced power state is a hibernate state, and wherein the instructions are further executable to determine the modified remaining battery capacity based on a reserve level of the battery that is sufficient to power the computing device to enter and wake from a sleep state before entering the hibernate state.

11. The computing device of claim 9, the instructions further executable to:

monitor a parameter varying with operation of the computing device; and

determine the minimum battery level based on the monitored parameter.

12. The computing device of claim 9, wherein the monitored parameter comprises an amount of information from a memory to be saved.

13. The computing device of claim 12, wherein the monitored parameter comprises priorities of redundant and non-redundant types of the information to be saved.

14. The computing device of claim 9, wherein the monitored parameter comprises at least one of an age, power capacity and number of refresh cycles of the battery.

15. The computing device of claim 9, wherein the monitored parameter comprises at least one of a temperature, processing speed, and power utilization of a component of the computing device.

16. An article comprising a non-transitory machine-readable storage medium storing instructions that upon execution cause a processor to:

determine a minimum battery level to transition a computing device to a reduced power state;

determine a modified remaining battery capacity based on the minimum battery level and an actual remaining battery capacity of a battery powering the computing device; and

report the modified remaining battery capacity in place of the actual remaining battery capacity.

17. The article of claim 16, wherein the reduced power state is a hibernate state, and wherein the instructions are further executable to determine the modified remaining battery capacity based on a reserve level of the battery that is sufficient to power the computing device to enter and wake from a sleep state before entering the hibernate state.

18. The article of claim 16, the instructions further executable to:

monitor a parameter varying with operation of the computing device; and

determine the minimum battery level based on the monitored parameter.

19. The article of claim 16, wherein the monitored parameter comprises at least one of an age, power capacity and number of refresh cycles of the battery.

20. The article of claim 16, wherein the monitored parameter comprises at least one of a temperature, processing speed, and power utilization of a component of the computing device.
