Abstract

Systems and methods are disclosed for providing battery health information to users of portable information handling systems. Battery health information is displayed to a user along with information concerning the limited life of a rechargeable battery. The battery health information may include, for example, a good condition indicator, a critical condition indicator and one or more intermediate condition levels. In addition, battery health information, customer battery usage information and other battery health related data can also be logged for later use in troubleshooting by users or remote technicians or for other desired purposes.

Claims

1. A method for informing a user of battery usable life information for an information handling system, comprising:

determining a current usable life condition for at least one rechargeable battery within an information handling system;

displaying normal level condition information to a user when the usable life condition is above a normal threshold level, the normal level condition information including usable life expectation information;

displaying critical level condition information to a user when the usable life condition below is a critical threshold level; and

displaying caution level condition information to a user when the usable life condition is below the normal threshold level and above the critical threshold level.

2. The method of claim 1, wherein the usable life expectation information comprises information informing the user that the rechargeable battery has a limited usable life and at some point will have to be replaced.

3. The method of claim 2, wherein the usable life expectation information is also displayed along with the critical level condition information and the caution level condition information.

4. The method of claim 1, wherein the displaying normal level condition information step comprises displaying a normal condition symbol and a normal condition message;

wherein the displaying critical level condition information step comprises displaying a critical condition symbol and a critical condition message; and

wherein the displaying caution level condition information step comprises displaying a critical condition symbol and a critical condition message.

5. The method of claim 1, further comprising storing battery usage data related to the battery.

7. The method of claim 1, further comprising displaying battery ordering information along with the caution level condition information or the critical level condition information, or both.

8. The method of claim 7, wherein the battery ordering information includes a link to a battery ordering website.

9. The method of claim 1, wherein the displaying caution level condition information step comprises displaying first caution level condition information when the usable life condition is below the normal threshold level and above a caution threshold level and displaying second caution level condition information when the usable life condition is below the caution threshold level and above the critical threshold level.

10. The method of claim 1, wherein the determining step comprises obtaining information from the battery and determining a percentage of usable life remaining as a representation for the current usable life condition for the rechargeable battery.

11. The method of claim 12, further comprising allowing a user to select the percentages used for the threshold levels.

12. The method of claim 10, further comprising determining a percentage of usable life remaining by obtaining a number of actual recharge cycles used for the battery and comparing it to an expected number of total recharge cycles for the battery, or by obtaining a current charge capacity for the battery and comparing it to a full charge capacity for the battery, or by doing both.

13. The method of claim 1, further comprising automatically displaying the caution condition level information to the user when the caution threshold condition level is reached and automatically displaying the critical condition level information to the user when the critical condition threshold level is reached.

6. The method of claim 6, further comprising allowing a user to select one of a plurality of rechargeable batteries for which battery usable life information will be displayed.

14. A battery health monitor for informing a user of battery usable life information for a rechargeable battery within an information handling system, comprising:

normal level condition screen information configured to be displayed to a user when a current usable life condition for a rechargeable battery is above a normal threshold level, the normal level condition screen information including usable life expectation information;

critical level condition screen information configured to be displayed to a user when the current usable life condition below is a critical threshold level; and

caution level condition screen information configured to be displayed to a user when the current usable life condition is below the normal threshold level and above the critical threshold level.

15. The battery health monitor of claim 14, wherein the usable life expectation information comprises information informing the user that the rechargeable battery has a limited usable life and at some point will have to be replaced.

16. The battery health monitor of claim 14, wherein the usable life expectation information is also displayed along with the critical level condition information and the caution level condition information.

17. The battery health monitor of claim 14, wherein the caution level condition screen information comprises first caution level condition screen information configured to be displayed when the usable life condition is below the normal threshold level and above a caution threshold level and second caution level condition screen information configured to be displayed when the usable life condition is below the caution threshold level and above the critical threshold level.

18. The battery health monitor of claim 14, wherein the current usable life condition for the rechargeable battery is based upon a percentage of usable life remaining for the rechargeable battery.

19. The battery health monitor of claim 14, wherein the percentage of usable life remaining is dependent upon a comparison of a number of actual recharge cycles used and an expected number of total recharge cycles for the battery, or upon a comparison of current charge capacity and a full charge capacity for the battery, or upon both.

20. The battery health monitor of claim 14, further comprising a selectable menu configured to allow a user to select one of a plurality of rechargeable batteries for which battery usable life information will be displayed.
