Abstract: Computing device expansion modules and control of their operation based on temperature are disclosed. According to an aspect, an expansion module includes an interface configured to operably connect to a computing device including a service manager. Further, the expansion module includes a controller configured to determine whether communication with the service manager of the computing device is enabled or not enabled. The controller is also configured to set a first temperature level at which operation of the expansion module is reduced in response to determining that communication with the service manager is enabled. Further, the controller is configured to set a second temperature level at which operation of the expansion module is reduced in response to determining that communication with the service manager is not enabled. The second temperature level is lower than the first temperature level.

Abstract: Methods and apparatuses for supplying power to processors in multiple processor systems are disclosed. Embodiments comprise a method of monitoring a parameter that is related to a first voltage potential coupled to the processor. When the parameter or condition monitored indicates that the first voltage is bad or faulty, the method generally involves isolating the voltage from the processor, disabling or resetting the processor, and coupling a second voltage potential to the processor. The method may also allow the computer system to continue operating with the processor disabled. Other embodiments comprise an error detection circuit for detecting an error related to a first voltage regulator, a disabling circuit to disable the first voltage regulator in response to the error, a processor isolating circuit, and a voltage switching circuit to supply voltage from a second voltage regulator to the processor.
