Board Warning Signs for A+
Short answer
- Capacitor swelling is a visible, objective indicator that a component has failed or is failing; it is a clear hardware-warning sign and often requires board or PSU service. - Inaccurate system date/time (clock resets) often indicates CMOS battery failure or firmware/board issues; repeated resets after power loss are a hardware clue. - Unusual noise (bearing failure, coil whine, electrical arcing) is a diagnostic clue; persistent or new noises warrant hardware inspection.
Why it appears on the exam
- Recognition: identify which visual or auditory signs point to platform-level hardware concerns. - Scenario judgment: given observed capacitor swelling, choose the correct escalation step. - Differentiation: decide whether inaccurate time is likely a network sync issue or hardware/CMOS battery issue based on context.
Key concepts
Concept 1
Required terms
capacitor swelling: Visible bulging or leakage on electrolytic capacitors on a board, indicating capacitor failure or imminent failure. inaccurate system date/time: System clock repeatedly losing time or reverting after shutdown, which can indicate CMOS battery failure or firmware/board problems. unusual noise: Persistent or abnormal mechanical or electrical sounds (e.g., high-pitched whining, coil whine, grinding) coming from the platform indicating possible mechanical or electrical issues.
Example
Scenario A: User reports that the system clock is wrong every time the PC is powered on -> consider CMOS battery or firmware board issue.

How Board Warning Signs works
- Capacitor swelling is a visible, objective indicator that a component has failed or is failing; it is a clear hardware-warning sign and often requires board or PSU service. - Inaccurate system date/time (clock resets) often indicates CMOS battery failure or firmware/board issues; repeated resets after power loss are a hardware clue. - Unusual noise (bearing failure, coil whine, electrical arcing) is a diagnostic clue; persistent or new noises warrant hardware inspection.
Example
Scenario B: Technician sees bulging capacitors near the power area of the motherboard -> escalate for hardware repair/service.
Concept 3
Common confusion
- Ignoring slight fan noise changes; persistent new sounds should be evaluated. - Replacing software settings for clock issues without checking CMOS battery or hardware cause. - Attempting board soldering or capacitor replacement in a support context; such repairs are outside this lesson focus.
Example
Scenario C: New grinding or rattling noise after a drop -> suspect mechanical damage (fan, bearing) and escalate.
