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.
