  • Publication number: 20240061594
    Abstract: An information processing apparatus includes a power circuit, a first controller, and a solid-state memory. The solid-state memory includes a second controller and a storage medium. The power circuit supplies operating power to a constituent member, selects a first power supply mode for converting supplied power into operating power when power is supplied from an external power source, and selects a second power supply mode for converting power from a secondary battery into the operating power when AC power is not supplied from an external power source. The second controller executes garbage collection for the storage medium regardless of an operation mode notified from the first controller when the first power supply mode is selected and determines whether garbage collection for the storage medium is necessary when the second power supply mode is selected and a change to a power saving mode is instructed as the operation mode.
