Provided are an information processing apparatus and a power-off control method of an information processing apparatus. An information processing apparatus includes a nonvolatile memory; a cache memory for caching data to be written into the nonvolatile memory; a power switch; a spatial change detecting section configured to detect a change in state of a space around the power switch; a notification section configured to send a user a notification; and a control section. The control section is configured to determine an action of a user likely to turn the power switch off, based on a detection signal outputted by the spatial change detecting section; operate the notification section to send a user a notification that the action is being performed, in response to recognizing the action; and write data stored in the cache memory into the nonvolatile memory after operating the notification section to send the user the notification.
