Question
After answering a service call, you find a customer's computer is dead. Which of the following checks would you perform first?
Question 3 options:
a)
Check the CMOS battery.
b)
Check for excessive EMI.
c)
Check the AC outlet voltage.
d)
Check to see if the power supply is functional.
Solution
The first step in troubleshooting a dead computer would be to check the most basic and easily verifiable things first. Therefore, the first check you should perform is:
c) Check the AC outlet voltage.
This is because if the AC outlet voltage is not correct, the computer will not receive the necessary power to function. This is a simple check that can quickly rule out power supply issues. If the AC outlet voltage is correct and the computer is still not working, then you can proceed to check other components such as the power supply, CMOS battery, and for excessive EMI.
