After a few months of use, you notice that the cooling fan in your laptop is running constantly, even when the laptop is idle. You know that the laptop fan should only run when the laptop is hot, so you’d like to troubleshoot by examining the temperature inside of the laptop. What’s the best way to determine the temperature inside of the laptop and its components?
A) Carefully remove the laptop’s outer case and install temperature leads that connect back to an external digital thermometer
B) Use a software utility to monitor internal laptop temperatures
C) Place an external thermostat outside of the laptop where the fan is blowing out warm air
D) Use the probes of a multimeter to determine the temperature inside of the laptop case
