SK0-005 server-hardware-installation-management Practice Question
A server displays a 'CMOS battery low' error during POST. After the technician replaces the CR2032 battery with a new one, the server still loses date and time settings when disconnected from power. Which of the following should the technician try NEXT?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify the new battery is functional and properly seated
Option A is correct because it is possible the new battery is defective, installed incorrectly, or not making proper contact. The first step is to verify the battery itself and its installation. Option B is wrong because a faulty motherboard is possible, but troubleshooting should start with the simplest and most likely cause. Option C is wrong because power supply fluctuations are unlikely to cause CMOS settings loss specifically when unplugged. Option D is wrong because the BIOS chip retaining settings is part of the CMOS circuit, but the immediate issue is likely the power source (battery) for the CMOS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Check the power supply for voltage fluctuations
Why it's wrong here
Voltage fluctuations do not typically affect CMOS settings retention when the system is unplugged; the battery maintains the settings.
- ✗
Update the BIOS firmware
Why it's wrong here
Updating BIOS is unlikely to resolve a hardware issue causing CMOS settings loss; the problem is at the physical level.
- ✗
Replace the motherboard
Why it's wrong here
While a faulty motherboard CMOS circuit is possible, it is a more extreme step and should not be the first action after a battery replacement.
- ✓
Verify the new battery is functional and properly seated
Why this is correct
A 'dead on arrival' battery or poor contact is a common cause. Checking with a multimeter or trying another new battery is the logical next step.
