CompTIA A+ Core 2 (220-1002) — Question 456

A computer's power light is on, but the screen is completely black. The user is unable to wake the computer and then contacts a technician. The technician asks the user to inspect the display cable, but it is securely connected at each end.
Which of the following steps should the technician ask the user to take NEXT?

Answer options

• A. Roll back the Windows updates
• B. Perform a startup recovery
• C. Perform a hard restart
• D. Boot from the last known-good configuration

Correct answer: C

Explanation

The correct step is to perform a hard restart, as this can resolve issues with a non-responsive display by resetting the hardware. Rolling back updates or performing a startup recovery may not address the immediate problem of the black screen, and booting from the last known good configuration is less likely to be effective since the issue might not be related to recent changes.
