Abstract
A personal computer is capable of communicating with a portable telephone by radio. A radio communication module establishes a radio link to the portable telephone. A field strength monitor section detects a field strength in a state where the radio link has been established. A power management control section sets the personal computer in a power save state when the field strength detected by the field strength monitor section lowers to a predetermined level.
Claims18
An information processing apparatus capable of communicating with a portable device by radio, comprising:
- means for establishing a radio link to the portable device;
- means for detecting a field strength in a state where the radio link has been established;
- and
- means for setting the information processing apparatus in a power save state when the field strength detected by said detection means lowers to a predetermined value.
An information processing apparatus capable of communicating with a portable device by radio, comprising:
- means for establishing a radio link to the portable device;
- means for detecting a field strength in a state where the radio link has been established;
- and
- means for controlling a specified program on the basis of the field strength detected by said detection means.
An information processing apparatus capable of communicating with a portable device by radio, comprising:
- means for executing logon processing to said information processing apparatus from said portable device on the basis of user authentication information transmitted from the portable device by radio;
- means for detecting a field strength from the portable device;
- and
- means for executing logoff processing of canceling a state of logon to said information processing apparatus from said portable device when the field strength detected by said detection means lowers to a predetermined value.
An operating state control method of controlling an operating state of an information processing apparatus capable of communicating with a portable device by radio, comprising the steps of:
- detecting a field strength in a state where a radio link to the portable device has been established;
- and
- setting the information processing apparatus in a power save state when the field strength detected in the detection step lowers to a predetermined value.
An operating state control method of controlling an operating state of an information processing apparatus capable of communicating with a portable device by radio, comprising the steps of:
- detecting a field strength in a state where a radio link to the portable device has been established;
- and
- controlling a specified program on the basis of the field strength detected in the detection step.
An operating state control method of controlling an operating state of an information processing apparatus capable of communicating with a portable device by radio, comprising the steps of:
- executing logon processing to said information processing apparatus from said portable device on the basis of user authentication information transmitted from the portable device by radio;
- detecting a field strength from the portable device;
- and
- executing logoff processing of canceling a state of logon to said information processing apparatus from said portable device when the field strength detected in the detection step lowers to a predetermined value.
