What This Guide Helps With
Addresses system failure to power on caused by external power, battery issues, connections, or software initialization faults before assuming internal hardware failure.
Step-by-Step Troubleshooting
Ensure Patient Safety
- Confirm no patient is actively being imaged.
- Move any patient to a functional ultrasound system if imaging is urgent.
Check Power Source
- Verify the power outlet is live by testing with a known working device.
- Ensure any extension cords or power strips are functional and rated for the system.
- Expected Outcome: System receives power; indicator lights may respond.
Inspect Power Cable and Connections
- Check that the system power cable is fully seated at both ends.
- Look for visible damage, fraying, or bent pins.
- Expected Outcome: Firm, secure connection with no visible damage.
Examine System Battery or UPS (if applicable)
- If using a backup battery or UPS, ensure it is charged and functioning.
- Remove the battery and attempt AC-only startup if supported.
- Expected Outcome: System powers on with AC power or indicates battery fault.
Check External Indicators
- Observe any LEDs on the control panel or power supply for error codes.
- Expected Outcome: Normal power-on light sequence or specific fault code.
Attempt Soft Reset / Power Cycle
- Disconnect power for 2–3 minutes.
- Reconnect and attempt startup.
- Expected Outcome: System initializes normally.
Verify Environmental Factors
- Ensure ambient temperature and humidity are within operational limits.
- Remove any external devices that may interfere with boot (USB drives, external storage).
- Expected Outcome: System powers on without external interference.
If the Problem Persists
All external power and connection causes have been ruled out.
The system should be:
Removed from service
Labeled Out of Service
Sent for manufacturer repair or internal bench evaluation
Knowing when to stop avoids patient risk and further damage.
Clinical Use Tip
Never attempt troubleshooting on an active patient.
Always move patients to a working system before investigating power failures.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"System will not power on when plugged into the room outlet."
Cause
What was observed during troubleshooting.
Example:
"External power and connections verified; soft reset did not resolve issue."
Resolution
What action was taken.
Example:
"Device removed from service, labeled Out of Service, and sent for repair."
Helpful Details to Include (If Known)
- Power outlet verified and tested
- Power cable condition and connections checked
- Battery/UPS status
- LED indicators observed
- Any error codes noted
- Final device status: Out of Service
Final Thought
Power-on failures are often caused by external connections or environmental factors. Clinical Engineering must approach systematically, rule out safe and verifiable issues first, and escalate appropriately. Documentation ensures continuity and patient safety.
That is successful troubleshooting.
