Abstract
A laptop computer with an alarm function using an LCD on/off switch includes: a microcomputer both for controlling the LCD back-light section on/off operation in response to the on/off state of an LCD on/off switch and for generating an interrupt signal; an alarm processor for determining whether or not the interrupt signal is a burglar alarm signal and outputs an alarm in case of a robbery; and a password determining section for comparing a password entered by a user with a previously set password and interrupting the generation of an alarm only when both passwords are identical. A burglar alarm is sounded when an interrupt occurs so when to indicate a robbery as the LCD on/off switch is turned on against a user's will during the operation of the computer. Also, it can interrupt the alarm by a user inputting a correct password during the generation of the alarm.
