Abstract

In a computer having an emergency calling function for detecting an emergency situation and for transferring an emergency call message previously set by a user to a preset emergency call telephone number, a non-volatile memory stores information which is not lost if power is turned off. A message/telephone number setter receives an emergency call message indicating an emergency situation and an emergency call telephone number which are input by a user and stores the received message and number in the non-volatile memory. An emergency call button generates an emergency detection signal when the user presses an emergency call button. A microprocessor receives the emergency detection signal from the emergency call button and restores the computer from a power-save state or a power-off state to a normal state. An emergency call controller reads the emergency call message and emergency call telephone number from the non-volatile memory and makes a telephone call to the emergency call telephone number to transfer the emergency call message, after an operational state of the computer has been restored to a normal state by the microprocessor.
