CompTIA A+ Core 1 (220-1101) — Question 442

When a PC is turned on, an error indicates that the date and time are wrong. Which of the following is the most likely cause?

Answer options

• A. Overheating RAM DIMMs
• B. HDD crash
• C. CMOS battery failing
• D. Capacitor swelling

Correct answer: C

Explanation

The correct answer is C, as a failing CMOS battery can lead to the loss of time and date settings when the computer is powered off. The other options, like overheating RAM DIMMs, HDD crashes, and capacitor swelling, do not directly affect the system's ability to maintain accurate date and time settings.
