System and method for predictive battery power management
An information handling system includes an embedded controller to capture a current battery power level of a battery that is a sole source of power of the information handling system. A service module may update a configuration table with anticipated power consumption associated with a component of the information handling system, wherein the anticipated power consumption is based on an operation, and predict whether the current battery power level is sufficient to complete the operation, including comparing the current battery power level with the anticipated power consumption of the component. If the current battery power level is sufficient to complete the operation, then the service module may execute the operation. If the current battery power level is insufficient to complete the operation, then the service module may provide one or more options associated with the operation based on a power management policy.

predicting whether the current battery power level is sufficient to complete the pre-boot operation based on the power requirement of the pre-boot operation associated with the initialization, wherein the predicting includes comparing the current battery power level with the power requirement of the pre-boot operation that includes an anticipated power consumption of a component associated with the pre-boot operation;
if the current battery power level is sufficient to complete the pre-boot operation, then executing the pre-boot operation; and
if the current battery power level is insufficient to complete the pre-boot operation, then providing one or more options associated with the pre-boot operation based on a power management policy, wherein the current battery power level is sufficient to execute the one or more options that includes putting another component that is not associated with the pre-boot operation into a low-power state.

3. The method of claim 1 , further comprising querying the anticipated power consumption of the component from a configuration table prior to the executing the pre-boot operation.
4. The method of claim 1 , further comprising updating a configuration table with an actual power consumption of the component subsequent to the executing the pre-boot operation or executing the one or more options.
5. The method of claim 1 , further comprising updating a low-power state table of the low-power state of the another component.
6. The method of claim 1 , wherein the one or more options include switching from a graphical user interface mode to a command line interface mode.
7. The method of claim 1 , wherein the one or more options include executing a subset of the pre-boot operation.
8. The method of claim 1 , wherein the one or more options include exiting from the pre-boot operation.
9. The method of claim 1 , further comprising configuring runtime properties of the information handling system prior to the executing the pre-boot operation or executing a subset of the pre-boot operation.
10. The method of claim 1 , further comprising in response to the battery not charging when plugged to a power source, updating a firmware of the battery.
11. The method of claim 1 , wherein the processor has a list of pre-boot operations to be executed in the information handling system, wherein each pre-boot operation of the pre-boot operations is associated with the anticipated power consumption of a plurality of components.
12. An information handling system, comprising:
an embedded controller to capture a current battery power level of a battery that is a sole source of power of the information handling system; and
a power management controller configured to:
update a configuration table with anticipated power consumption associated with a component of the information handling system, wherein the anticipated power consumption is based on a pre-boot operation;
predict whether the current battery power level is sufficient to complete the pre-boot operation, including comparing the current battery power level with the anticipated power consumption of the component;
if the current battery power level is sufficient to complete the pre-boot operation, then to execute the pre-boot operation; and
if the current battery power level is insufficient to complete the pre-boot operation, then to provide one or more options associated with the pre-boot operation based on a power management policy, wherein the current battery power level is sufficient to execute the one or more options, and wherein the one or more options includes putting another component not associated with the pre-boot operation into a low-power state prior to executing the one or more options.
13. The information handling system of claim 12 , wherein the power management controller includes a unified extensible firmware interface service.
14. The information handling system of claim 12 , wherein the power management controller includes an operating system service.
15. The information handling system of claim 12 , the power management controller is further configured to update the configuration table with a latest battery power level subsequent to the execution of the pre-boot operation.
16. The information handling system of claim 12 , wherein the power management controller is further configured to update the configuration table with an actual power consumption of the component subsequent to the execution of the pre-boot operation.
17. A non-transitory computer-readable medium including code that when executed causes a processor to perform a method, the method comprising:
monitoring performance of a battery based on a current battery power level, wherein the battery is configured as a sole source of power of an information handling system, wherein the monitoring of the performance of the battery is during an initialization of the information handling system;
predicting whether the current battery power level is sufficient to complete a pre-boot operation, including comparing the current battery power level with anticipated power consumption of a component associated with the pre-boot operation;
