Test the power supply
replace the CMOS battery
check the AC outlet
reseat the hard drive controller cable E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: A. Test the power supply
A computer that is completely dead and was working the day before is likely to have a problem with the power supply. The power supply is responsible for providing power to all of the components in the computer, so if it is not working properly, the computer will not turn on.
To test the power supply, you can use a multimeter to measure the voltage output of the power supply. The voltage output should be within the specifications of the computer’s power supply. If the voltage output is not within the specifications, the power supply needs to be replaced.
Here are some brief explanations of the other options:
- Option B: Replacing the CMOS battery is not likely to fix a problem with a computer that is completely dead. The CMOS battery is a small battery that stores the BIOS settings. If the CMOS battery is dead, the computer may not be able to save the BIOS settings, but it should still be able to turn on.
- Option C: Checking the AC outlet is a good first step to troubleshoot a computer that is not turning on, but it is not likely to fix a problem with a computer that is completely dead. If the AC outlet is not working, the computer will not turn on, but if the AC outlet is working, the computer should turn on even if there is a problem with the power supply.
- Option D: Reseating the hard drive controller cable is not likely to fix a problem with a computer that is completely dead. The hard drive controller cable is a cable that connects the hard drive to the motherboard. If the hard drive controller cable is not properly connected, the computer may not be able to access the hard drive, but it should still be able to turn on.
- Option E: None of the above is the correct answer.
