Abstract
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.
Claims16
An apparatus comprising:
- a body having a CPU therein;
- a lid, wherein the apparatus is used by opening the lid for the body;
- a sensor circuit which determines whether said lid is opened or closed;
- a first circuit, coupled to said sensor circuit, which stops a first operating state and shifts the apparatus to a transfer mode in response to sensing that the lid is closed, wherein the transfer mode stops an operating state of a device that may be damaged by a transfer of the apparatus without stopping the CPU and without stopping devices that take a predetermined amount of time to start up, wherein the devices that take a predetermined amount of time to start up comprises at least a wireless LAN device;
- and
- a second circuit, coupled to said sensor circuit, which shifts the apparatus to the first operating state in response to sensing that the lid is opened, wherein the second circuit clears the stoppage of the operating state of the device that may be damaged by a transfer of the apparatus.
A method comprising:
- a first step of setting a portable electronic apparatus in a first operating state;
- a second step of, in response to determining that a lid of the portable electronic apparatus is closed in the first operating state, shifting the portable electronic apparatus to a transfer mode in which an operating state of a device that may be damaged while the portable electronic apparatus is being transferred is temporarily stopped with a CPU of the portable electronic apparatus and devices that take at least 10 seconds to start up remaining operative, wherein said devices that take at least 10 seconds to start up comprises at least a wireless LAN device;
- and
- a third step of shifting the portable electronic apparatus to the first operating state in response to opening of the lid, wherein the third step clears the stoppage of the operating state of the device that may be damaged by a transfer of the apparatus.
A computer-readable product comprising a storage medium which stores instructions which when executed by a portable computer perform a method comprising:
- (a) in response to closing of a lid of the portable computer in a first operating state, shift the portable computer to a transfer mode in which an operating state of a device that may be damaged while the portable computer is being transferred is temporarily stopped with a CPU of the portable computer and devices that take at least 10 seconds to start up remaining operative, wherein said devices that take at least 10 seconds to start up comprises at least a wireless LAN device;
- and
- (b) shift the portable computer to the first operating state in response to opening of the lid, wherein the stoppage of the operating state of the device that may be damaged by a transfer of the apparatus is cleared.
