A method for docking/undocking a portable computer to/from an expansion unit is disclosed. The portable computer includes a main battery, and the expansion unit includes a second battery. In response to an eject event, the condition of the second battery is determined. If the second battery is in a discharging condition, a power supply route is switched from the second battery of the expansion unit to the main battery of the portable computer. If the second battery is in a charging condition, the charging condition is suspended. At this point, a hot undocking of the portable computer from the expansion unit can be performed.

A power control method for a magnetic disk unit is disclosed. The method includes identifying a type of a last instruction sent to a magnetic disk unit and, in response to identifying the type, setting a wait time that varies according to the type. In response to the wait time having elapsed after a completion of processing ordered by the last instruction, an idle instruction is sent to the magnetic disk unit for placing the magnetic disk unit in an idle state in which power consumption is reduced.

A portable notebook PC comprising a lid is able to avoid possible trouble during its transfer (as when a user carries the PC with him or her) and is able to reduce the time required to start up after the transfer. The portable notebook PC has a normal operating mode in which a user can utilize the notebook PC, a power saving mode in which an operation performed in the normal operating mode is saved to a predetermined memory so that power consumption can be reduced by using the minimum power required to retain data, and a transfer mode in which the system is temporarily disabled by stopping functions that may become defective during the transfer with a CPU remaining operative.

A computer program or the like is provided for reducing changes to the setting information by the computer. A management apparatus is provided for managing devices connected to a computer using a layered structure including a managing section for setting information associated with each of the devices by recording it in a setting information database using a layered structure; an adding section, if an existing device has been replaced by a new device for adding the setting information for the new device into the setting information database; a condition deciding section to determine whether the existing device and the new device have a predetermined relationship; and a changing section, if the existing device and the new device have the predetermined relationship, for managing the setting information for a low level device, which is a device managed as a lower layer of the existing device, as the lower layer of setting information for the new device and recording it in the setting information database.
摘要:
The present invention relates to an input method using the pointing device in which the pointing device's ON operation causes an application to recognize that the state of the pointing device has transitioned to an ON state and the pointing device's OFF operation causes the application to recognize that the state of the pointing device has transitioned to an OFF state. The input method includes responding to the ON operation of the pointing device maintained in a certain period and bringing about a latch state in which the pointing device remains in the ON state for the application even if the OFF operation of the pointing device has taken place; and executing a program for informing a user that the latch state has been brought about.
