Abstract: Embodiments of the present disclosure disclose a method and associated device for determining when an air filter needs replaced in an electronic device. The method comprises measuring the power needed to produce a predetermined output in a fan or related device that receives air through the air filter and comparing the measured power to previous measurements. When the amount of power needed is greater than a threshold, a dirty filter message or alert is produced.

Abstract: A computing device includes a peripheral component interconnect (PCI) card and a heater apparatus. The heater apparatus is located proximate to the PCI card and configured to heat the PCI card.

Abstract: An improved method and system for heating and cooling an electronic device, when internal temperatures are below safe operating ranges. To do so, the system selectively heats or cools each zone of the electronic device. This may be done by individual heaters and/or cooling system for each separate zones. Alternatively, or in addition too, the system can selectively open and close baffles, causing fresh ambient air to enter and/or recirculate heated air in a device’s enclosure. This keeps sensitive components of the computing device, such as processors and memory from suffering damage, by operating them at temperatures that are either too cold or too warm.

Abstract: Embodiments of the invention may provide an improved method for pre-heating an electronic device such as an information handling system, when internal temperatures are below safe operating ranges. To do so, the system selectively heats the entire device or select zones of the electronic device for a predetermined amount of time when the system is restarted after a period of time sufficient to bring the system to ambient temperatures. The predetermined amount of time is determined based on measured ambient temperatures. Using a table that corresponds the ambient temperatures to a time that a component needs to heat up to a nominal temperature in a zone, the predetermined time can be calculated.
