Patent ID: 8095246

Claim:
A system for automatically determining a temperature tolerance range of an electronic device, the system comprising: a temperature regulator to regulate a temperature surrounding the electrical device; a main computer connected to the temperature regulator and the electronic device, the main computer comprising: a processor; and a memory unit connected to the processor, and storing plurality of modules each of which contains one or more computerized instructions being executed by the processor, wherein the plurality of modules comprises: a control module directing the temperature regulator to regulate the temperature surrounding the electronic device to equal to a reference temperature plus a temperature difference for the first time, regulate the temperature surrounding the electronic device to equal the previous regulated temperature plus the temperature difference for every time after the first time when a limit value of the temperature tolerance range is being determined, and supply a voltage to the electronic device after regulating the temperature surrounding the electronic device; wherein the reference temperature is the temperature at which the electronic device can power on under normal conditions; a determination module to determine whether the electronic device is powered on at the regulated temperature, and output a determination that the electronic device is powered on or has failed to power on, wherein if the electronic device is powered on, the electronic device implements an application to test hardware of the electronic device, the determination module also determines whether the test is successful after performing the test software, and outputs a determination that the test is successful or has failed, wherein if the test is successful, the control module directs the temperature regulator to continue to regulate the temperature surrounding the electronic device to equal the previous regulated temperature plus the reference temperature; if the determination denotes that the electronic device has failed to power on or determination denotes that the test has failed is received, the control module stops supplying the voltage to the electronic device and outputs a control signal; and a recording module to record a temperature equaling the temperature under which the electronic device has failed to power on or the test has failed less the temperature difference as the limit value of the temperature tolerance range after receiving the control signal.
