Personal computer for setting, in a software setup operation normal/reverse display, connection of an external device, and an automatic display off function
First Claim
1. An information processing system including means for communicating address and data information in the system, means for supplying a driving power from a battery to the system, a memory, a peripheral device, means for accessing the peripheral device through the communicating means, coupled to the supplying means, for controlling the driving power to the peripheral device by using a setup utility stored in the memory, the controlling means comprising:
- said memory including means for storing a power control interval, the interval representing an interval since the peripheral device has last been accessed;
means for executing the setup utility at a power-on of the system and displaying the stored power control interval;
means for selecting a power control interval of the system, coupled to the executing means;
means, coupled to the selecting means, for determining whether the selected power control interval is different from said stored interval;
means for writing the selected interval in the storage means, thereby updating the stored interval when the selected interval is different from the stored interval;
means for determining whether the peripheral device is being accessed;
means for counting an interval since the peripheral device has been last accessed when the determining means determines that the peripheral device is not being accessed; and
means, coupled to the counting means, for outputting a power control signal to the peripheral device when the counted interval exceeds the stored power control interval.

Abstract
A personal computer, wherein a setup processing is performed to select a display mode, either a normal-display mode or a reverse-display mode, and also to select one of the external devices such as a printer and an external floppy disk drive. Also, a display auto-off mode and a display auto-off period are set during the setup processing. A period is measured during which no data is input from a keyboard. When the measured time value exceeds the display auto-off period, the supplement of power to the back light is stopped automatically.

10. A method for controlling a driving power to a peripheral device in an information processing system, comprising the steps of:
-
executing a setup utility stored in a computer memory at a power-on of the system and displaying a stored power control interval for the peripheral device, the power control interval representing an interval after which when the peripheral device is not accessed, the driving power to the peripheral device is not to be stopped; selecting a power control interval for the system; determining whether the selected interval is different from the stored interval; when the selected interval is different from the stored interval, storing the selected interval in the memory to update the stored interval; determining whether the peripheral device is being accessed and counting, when the peripheral device is not being accessed, an interval since the peripheral device has last been accessed; and outputting a power control signal to the peripheral device when the counted interval exceeds the stored interval, thereby controlling the driving power to the peripheral. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
