If a laptop touchpad does not work but an external mouse works, what is the most reasonable conclusion?

Answer and explanation

Correct answer: The touchpad may have a setting, driver or hardware problem

The governing troubleshooting principle is to isolate the failed component by comparing related devices. Because an external mouse moves the pointer successfully, the operating system and general pointer processing are working. Attention should therefore move to the touchpad’s enable setting, driver, cable or hardware. A faulty processor, monitor or hard disk would not specifically explain a working external mouse, so option A is correct.
