Abstract: According to one embodiment, a processor executes a process of setting an information processing apparatus to be in a power saving state in which the internal, display is dimmed or turned off and supply of the display signal to an external display is stopped, when a time elapsed after input data is last received from an input device reaches a setting time. The elapsed time is measured by using a timer. A system controller executes a process of cyclically transmitting an event capable of clearing the timer to the processor, under a condition that the external display is connected to the external display connection terminal.

Abstract: According to one embodiment, an electronic apparatus includes a first housing and a second housing. The first housing includes a first wall, a second wall opposite to the first wall, and a third wall between the first wall and the second wall. The third wall faces the second housing when the second housing is raised from the first housing. The third wall includes an outmost portion of the third wall in a direction from a fan toward the third wall, a first area obliquely extending between the outmost portion and the first wall and including a first opening, and the second area obliquely extending between the outmost portion and the second wall and including a second opening.

Abstract: In a battery-driven portable computer, a battery pack is constituted by m battery sets connected in series each including n lithium-ion secondary battery cells connected in parallel. A voltage monitor for monitoring the voltage of the terminal electrode of each battery set and a charger for independently appropriately charging each battery set in accordance with a monitor result are arranged, thereby realizing battery driving by a lithium-ion secondary battery pack having a large capacity. A computer system monitors the voltages of the battery cells which are part of a secondary battery by comparing the battery voltages with a predetermined voltage value in order to detect overdischarge (undervoltage) or overcharge (overvoltage), outputs this information outside of the battery pack, and terminates processing prior to a circuit disconnect.
