CompTIA A+ Core 1 (220-1201) — Question 92

An end user reports that their laptop has a blank screen. A technician observes the keyboard lights are on, and the fan is running. Which of the following should the technician do next?

Answer options

• A. Check the display ribbon cable.
• B. Contact vendor support.
• C. Replace the inverter.
• D. Connect to an external monitor.

Correct answer: D

Explanation

Connecting to an external monitor is a logical next step to determine if the laptop's issue is with the internal display or the graphics output. If the external monitor works, it suggests a problem with the laptop's screen or connections, while if it doesn't, the issue may lie with the laptop's hardware or graphics. The other options involve more invasive or less immediate troubleshooting steps.
