1. A method, comprising operating an information handling system having power-consuming circuitry that is coupled to selectably receive power from an external power source or from one or more internal battery cells of a battery system of the information handling system, the power-consuming circuitry comprising at least one first programmable integrated circuit coupled to a solid state drive (SSD) by a peripheral component interconnect express (PCIe) link; where the method further comprises:
determining if a current value of a remaining battery capacity of the battery cells is less than or equal to a predefined low battery capacity threshold value while the power-consuming circuitry is currently receiving power only from the internal battery cells of the battery system, and then:
operating the SSD in a low battery SSD power mode if the current value of the remaining battery capacity of the battery cells is determined to be less than or equal to the predefined low battery capacity threshold value while the external power source is not providing external power to the power-consuming circuitry of the information handling system, and
operating the SSD in a default SSD power mode if the current value of the remaining battery capacity of the battery cells is determined to be greater than the predefined low battery capacity threshold value or if the external power source is providing external power to the power-consuming circuitry of the information handling system; and
where the low battery SSD power mode comprises first peripheral component interconnect express (PCIe) link power management settings and first non-volatile memory express (NVMe) power settings, and where the operating the SSD in the low battery SSD power mode comprises operating the SSD using the first peripheral component interconnect express (PCIe) link power management settings and the first non-volatile memory express (NVMe) power settings;
where the default SSD power mode comprises different and second peripheral component interconnect express (PCIe) link power management settings and second non-volatile memory express (NVMe) power settings, and where the operating the SSD in the default SSD power mode comprises operating the SSD using the second peripheral component interconnect express (PCIe) link power management settings and the second non-volatile memory express (NVMe) power settings;
where the power-consuming circuitry consumes greater power when the SSD operates in the default SSD power mode than when the SSD operates in the low battery SSD power mode; and
where the first NVMe power settings comprise a first value of Idle Time Prior to Transit (ITPT) that is less than a second value of ITPT of the second NVMe power settings.
