220-1201 Exam Dumps : CompTIA A+ Core 1 Exam (2025)

When a newly built workstation shows no response at all—no fans spinning, no indicator LEDs, and no POST activity—this indicates that the system is not receiving the signal to power on. Since the technician has already verified that all primary power connectors are fully seated (including the 24-pin ATX motherboard connector and the 4-pin or 8-pin CPU power connector), the most likely cause is that the case header pins are not connected to the motherboard.

According to CompTIA Core 1 (220-1201) hardware installation and troubleshooting concepts, the power button on the computer case connects to the motherboard via the front-panel (system panel) header, specifically the PWR_SW pins. If this connector is missing, improperly placed, or connected to the wrong pins, pressing the power button will do nothing because the motherboard never receives the power-on signal.

Incorrectly seated RAM typically allows the system to power on but prevents successful POST, often resulting in beep codes or error lights. An underpowered PSU usually causes instability, random shutdowns, or failure under load rather than complete inactivity. A faulty CPU fan connector generally triggers a BIOS warning or shutdown after power-on, not total failure to start.

This scenario directly matches CompTIA’s emphasis on checking front-panel connections as a primary step when a system does not power on at all.

Thermal printerscreate images using aheated print headon specially coated thermal paper. Vertical white lines indicate thatpart of the heating element is dirty or blocked, preventing heat transfer to the paper. Cleaning the print head (heating element) will restore full functionality.

Option A:Thermal printers donot use ink or toner, so this is not applicable.

Option B:Wrong paper could cause blank output, but consistent vertical lines point to the print head.

Option C:Maintenance kits are typically for laser printers, not thermal printers.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.7: Given a scenario, troubleshoot common printer problems.

D. POST Code Beeps:

During the Power-On Self-Test (POST), the BIOS performs checks on system hardware, including RAM. If the RAM is faulty, POST may produce a series of beep codes indicating memory issues.

These beep codes are often the first sign of RAM-related problems, especially if the BSOD occurs randomly.

Incorrect Options:

A. Wrong BIOS configurations: Incorrect BIOS settings may cause boot errors, but they are less likely to cause random BSODs.

B. Continuous reboots: Continuous reboots could result from multiple hardware or software issues but do not specifically point to RAM.

C. Distended capacitors: Faulty capacitors typically affect the motherboard, not the RAM.

Key Takeaway: POST beep codes are a common diagnostic tool for identifying RAM-related issues.
