A point-of-sale (POS) device includes a processor, a battery, a transaction object reader, a printer with a printer controller, and optionally a temperature sensor. The processor determines a present power discharge capability rate of the battery, optionally based on a temperature measured by the temperature sensor. The processor also calculates a first estimated power draw rate based on a first setting value for at least one of the components of the POS device, such as the printer. If the first estimated power draw rate is dangerously close to the present power discharge capability rate of the battery, a second estimated power draw rate is calculated based on a second setting value for the one or more components. If the second estimated power draw rate is no longer dangerously close to the present power discharge capability rate of the battery, the components are set to the second settings value.

A method includes receiving a power supply unit (“PSU”) replacement signal for a power supply chassis that includes plurality of supply enclosures. Each power supply enclosure includes a plurality of power supply units (“PSUs”). Each of the PSUs in the power supply enclosures is connected to a power bus powering computing equipment. PSU redundancy policy has at least one PSU being redundant. In response to the PSU replacement signal, the method calculates a power cap limit equal to a capacity of the plurality of supply enclosures that are not being removed. Power consumption of the computing equipment is limited to the power cap limit. In response to detecting a replacement power supply enclosure, the method recalculates the power cap limit based on all of the PSUs according to the PSU redundancy policy. Power consumption of the computing equipment is limited to the recalculated power cap limit.
