CompTIA A+ Core 1 (220-1101) — Question 263

A technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots. When the technician tries to turn on the laptop, the computer starts beeping and does not pass POST. The technician double-checks the newly installed RAM and notices a motherboard message indicating low voltage. Which of the following is the most likely cause of this issue?

Answer options

• A. Faulty power adapter
• B. Incorrect BIOS settings
• C. Failing CMOS battery
• D. Unsupported memory

Correct answer: D

Explanation

The most likely cause of the issue is that the newly installed RAM is not supported by the laptop, which leads to the low voltage message and failure to pass POST. A faulty power adapter, incorrect BIOS settings, or a failing CMOS battery would not typically result in such symptoms related to RAM compatibility.
