ABSTRACT:
A portable computer system made up of a voltage level detecting portion for detecting the output voltage level of a battery; a switching portion connected between the battery and at least one peripheral device for turning on/off the peripheral device; a battery charging state determining portion for receiving a voltage level signal from the voltage level detecting portions, comparing it with a reference voltage level between the normal operating voltage level and the lower voltage level that is relatively lower than the normal operating voltage level, determining the charging state of the battery and outputting a control signal; and a control portion for controlling the turning on or off of the switching portion in response to the control signal, thereby controlling a hard disk drive to store current data at the reference voltage level.
