"Method for Preventing Over-Heating of a Device within a Data Processing System" in Patent Application Approval Process

July 15, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- A patent application by the inventors DAS, HIMANSU S. (IN); CHOU, STEVEN C. (TAIPEI, TW); HUANG, RICHARD (TAIPEI, TW); LIN, JEFF (TAIPEI, TW), filed on December 9, 2013, was made available online on July 3, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to International Business Machines Corporation.

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to electronic devices in general, and, in particular, to a method for preventing over-heating of an electronic device within an information processing system.

"With the continued improvement and development of faster components used in information processing systems, the complexity of heat management for the components also increase. Incidentally, the effective heat management for information processing systems becomes a big challenge.

"In general, the power status of an information processing system can typically be defined at least as follows: S0: operational status, the actual status is in normal operation; S1: first standby status, which will cut off the power for some peripheral devices, generally stopping power supply to hard disk and monitor, and so on, but still supplying power to central processing unit (CPU), fan memory, fan, and so on; S2: second standby status, which will cut off the power for some peripheral devices, generally stopping power supply to hard disk, monitor, central processing unit, cache memory, and so on; S3: suspend status, which will cut off the power for some peripheral devices, generally stopping power supply to hard disk, monitor, central processing unit, cache memory, and so on, but only supplying power to random access memory (RAM) for storing the operation status in the RAM; S4: hibernate status, which will turn off the main portion of system power and store the operation status in the hard disk; S5: soft off status, which will turn off all the power except the power management unit of the core chip; and G3: mech off status, which also turn off the power management unit of the core chip.

"Thus, when the status of power supply is suspend status S3, soft off status S5, or hibernate status S4, the main power of the power supply device is turned off, but the standby power is still supplied to the target devices. As a result, the temperatures of various devices within an information processing system will continue to increase. Consequently, it would be desirable to prevent those devices from being damaged by over-heating."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In accordance with a preferred embodiment of the present invention, a determination is made whether or not a power status of an information processing system is set to turn on a main power of a power supply device, wherein the information processing system includes a target device. If the power status of the information processing system is set to turn on a main power of a power supply device, a power switch of the target device is turned on. If the power status of the information processing system is not set to turn on a main power of a power supply device, another determining is made whether or not the target device is set to operate based on a user's setting. If the target device is set to operate based on the user's setting, the power switch of the target device is turned on. If the target device is not set to operate based on the user's setting, the power switch of the target device is turned off.

"All features and advantages of the present invention will become apparent in the following detailed written description.

BRIEF DESCRIPTION OF THE DRAWINGS

"The invention itself, as well as a preferred mode of use, further objects, and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:

"FIG. 1 is a block diagram of an information processing system, in accordance with a preferred embodiment of the present invention;

"FIG. 2 illustrates the configuration of a non-volatile memory for the target device within the information processing system from FIG. 1;

"FIG. 3 is a high-level logic flow diagram of a method for preventing over-heating of a target device within an information processing system, in accordance with a preferred embodiment of the present invention; and

"FIGS. 4A-4B are high-level logic flow diagrams of a method for preventing over-heating of a target device within an information processing system, in accordance with a second embodiment of the present invention."
