According to one embodiment, an information processing apparatus includes a key matrix unit having a plurality of switches, a plurality of operation keys which are provided in association with a part of the plurality of switches, and a first detection unit which executes a scan process for the key matrix unit, thereby detecting on/off states of the plurality of switches, the first detection unit executes a predetermined process in a case where the first detection unit detects that the switches, which are not associated with the operation keys, are in an ON state.

Information processing apparatus and liquid detection method

A portable information apparatus, such as a portable computer, comprises a housing having a top wall, a keyboard supported by the top wall, and a display unit rotatably coupled to the housing. The display unit can be rotated between a closed position where it covers the top wall and the keyboard and an opened position where it exposes the top wall and the keyboard. The housing incorporates a circuit component and a heatsink. The circuit component generates heat while operating. The heatsink radiates the heat the circuit component generates. The heatsink has a heat-radiating section exposed along the top wall of the housing. The heat-radiating section is opposed by the display unit, no matter whichever position, including the closed and opened positions, the display unit has been rotated to.

A portable computer that includes a first ROM for storing an OS, a second ROM for storing at least one piece of existing application software, and a flat display panel for displaying at least one icon to read out the existing application software stored in the second ROM. Since the DOS and the application program are respectively stored in a DOS ROM and an application ROM, the DOS or the application can be quickly executed without install processing from floppy disks.

A flash memory used as a BIOS-ROM has a main block storing a BIOS and a boot block storing minimum programs executed in initializing the system. Upon a power-on operation, when a rewriting unit is connected to an expansion bus connector, a new boot block stored in a ROM of the rewriting unit is written in the flash memory. Upon the power-on operation, a key depression detecting routine in the boot block is executed to check whether a predetermined key is depressed. If the predetermined key is determined to be depressed, a rewriting program in a floppy disk is loaded in the system and executed, thereby rewriting the content of the main block into the BIOS file stored in the floppy disk.

Computer system having BIOS (basic input/output system)-ROM (Read Only

When the MS-DOS is not installed from an FDD or an HDD but is installed from a built-in DOS ROM arranged in a memory space in which bank access to the computer main body can be performed, at the time the system power is turned on, a menu display processing program stored in the DOS ROM is executed by the DOS. Upon execution of the program, the arrangement of menu icons can be arbitrarily changed on the menu screen.
