Abstract
A computer system apparatus and method therefor are described which are appropriately power-controllable corresponding to each usage-situation. The computer system includes a PC main body and a digitizer wherein the usage-situation of the system is detected. If one of the predetermined usage-situations, such that the digitizer is mainly employed, is adopted, a target power saving mode is determined corresponding to installation or non-installation of an AC adapter, remaining amount of a DC battery, data upload frequency from the digitizer, and other conditions. In addition, in the case that the PC main body is in a power saving mode, the PC main body returns to the normal mode if data upload from the digitizer is requested. After completing the upload, the main body returns to an appropriate power saving mode.
