Abstract

PURPOSE: To shorten initialization processing time by providing a means to turn on the operation of a personal computer after detecting that a tiltable display part is opened by a display part switch. CONSTITUTION: When a user opens the tiltable display part 1, it is detected that the tiltable display part 1 was opened by the display part switch 2 connected to a hinge 4 installed between the tiltable display part 1 and a main body 5. When it is detected that the tiltable display part 1 was opened by the display part switch 2, power is supplied to various parts by operating a power supply part by a switch control part 22, and for instance, a CPU 11 is informed that the tiltable display part 1 was opened through a switch control part interface 15 while the display part is left stopping. When the CPU 11 recognizes this, it executes the initialization processing of the various parts. When it is detected that a switch 3 was turned on after the initialization processing of the various parts, the display part is made to operate by the switch control part 22, and the CPU is informed that the switch 3 was turned on.
