An information processing apparatus includes a first storage storing an operating system program, a second storage including a boot program storage area, a first area and a second area, and a processor coupled to the first storage and the second storage. The processor writes the first path information, which is stored in the first area and used to boot up the operating system program, into the second area, upon first booting-up, compares the first path information in the first area and the second path information in the second area upon second booting-up subsequent to the first booting-up, determines whether the operating system program indicated by the first path information is to be booted up based on a result of the comparing, and writes the second path information into the first area when the operating system program indicated by the first path information is not to be booted up.

Apparatus and method for selecting and booting an operating system based on path information

An information processing apparatus having a processing circuit to execute a program by operating at a set operating frequency, including: a measuring section that measures an elapsed time from the user's last operation; a notification section that notifies operation allowing frequencies in the processing circuit and instructs, in response to an elapsed time longer than a predetermined threshold time measured by the measuring section, fixing to a specific low-operating frequency among the operation allowing frequencies and in response to the user's operation in an input section, instructs to release the fixing; and a setting section that selects an operating frequency from among the operation allowing frequencies according to a processing situation and sets the selected operating frequency to the processing circuit and upon release of the fixing, restarts setting of an operating frequency selected from among the operation allowing frequencies, according to a processing situation in the processing circuit.

Information processing apparatus, operation control method and operation control program storage medium

An information apparatusreceiving power from a portable power sourceis provided with an external power receiving sectionreceiving the power by connection to non-portable power sourcesand; an operation section SW switching supply and cutoff of the power from the non-portable power sourcesthat are connected to the portable power sourceor to the external power receiving section; judging sectionsandfor judging, when the information apparatusis activated by the supply of power, whether or not the activation is a first activation since the information apparatusis shipped from a factory; and an informing sectionfor prompting a user to connect the external power receiving sectionto the non-portable power sourcesandwhen the activation is the first activation since the information apparatusis shipped.
