System and method for intelligent power management of firmware updates
An information handling system includes power inputs, a battery, a BMC, a memory, and a processor. The BMC determines which of the power inputs are coupled to associated power sources, and a first duration of time that the battery can provide power to the information handling system. The memory stores a firmware element. The processor receives a firmware that includes a second indication as to which of the power inputs are to be coupled to their associated power source as a condition for saving the firmware update, and that includes a second duration of time that it is expected to take to save the firmware update. The information handling system saves the firmware update to the memory when the first indication matches the second indication and when the first duration of time is greater than the second duration of time.
