Abstract

The method for controlling a computer that notifies an operating system of a request event corresponding to a device event from hardware. A device event may be generated, for example by a user operating a keyboard or mouse connected to the computer. That is, the device event occurs when a certain event is provided to the hardware of the computer. A request event causes a process corresponding to the device event to be performed under the control of an operating system. Then a response event from the operating system caused by the notification of the request event is accepted and a process event corresponding to the accepted response event is output to the hardware.

Claims

1. A method for controlling a computer for a device event provided from hardware, in which said computer comprises a basic system for notifying an operating system of a request event corresponding to the device event in response to the device event from said hardware, accepting a response event of the operating system caused by the notification, and outputting a process event corresponding to the accepted response event to the hardware, said method comprising:

notifying said operating system of an additional event associated with the response event after receiving said response event in said basic system;

accepting an additional response event corresponding to said additional event from said operating system; and

,

outputting an additional process event corresponding to said accepted additional response event to said hardware,

wherein said process event comprises an event for switching said computer from an energy-saving mode to a normal mode, and said additional process event comprises an event for switching said computer from said normal mode to the energy-saving mode after said process event is output.
