Explanation
When troubleshooting a computer that will not turn on, it is critical to begin with basic power checks. This includes ensuring the computer's power cable is securely connected, verifying the power source (such as a power strip) is functional, and confirming the power button is engaged. These steps help identify or rule out common issues before investigating more complex hardware or software problems.
- A. Correct.
Ensuring the computer's power cable is plugged into the outlet is essential as the computer cannot receive power if it is disconnected.
- B. Correct.
If a power strip or surge protector is being used, it must be turned on and functional to supply power to the computer.
- C. Incorrect.
Checking the monitor's power cable is irrelevant to the computer not turning on, as the monitor is already powered on.
- D. Correct.
The computer's power button may not be engaged correctly, so ensuring it is being properly pressed is a necessary troubleshooting step.
- E. Incorrect.
The keyboard and mouse connections are unrelated to the computer's ability to power on and would not resolve this issue.
