What This Guide Helps With
Addresses system startup failure or freezing caused by power issues, peripherals, software lockups, or environmental factors before assuming internal hardware failure.
Step-by-Step Troubleshooting
Ensure Patient Safety
Confirm the system is not in active clinical use. Move the patient to another functioning ultrasound system before troubleshooting.
Verify Power Source
Check that the system is plugged into a known-good hospital-grade outlet. Test the outlet with another device.
Expected Outcome: System receives stable power. No power may indicate outlet or power cord issue.
Inspect Power Cord and Connections
Ensure the power cord is fully seated at both the wall and system. Look for damage or loose connections.
Expected Outcome: Secure connection eliminates intermittent power or startup failure.
Check Power Indicator Lights
Observe system LEDs when attempting to power on.
- No lights: likely power input issue
- Lights but no boot: possible system hang or internal issue
Why it matters: Helps differentiate between power vs. system-level failure.
Perform a Hard Power Reset
Turn the system off, unplug from power, wait 60 seconds, then reconnect and power on.
Expected Outcome: Clears temporary faults or system lockups.
Disconnect External Peripherals
Remove all probes, USB devices, printers, and network cables. Attempt to boot with minimal configuration.
Expected Outcome: System boots normally if a peripheral was causing the freeze.
Check for Overheating or Vent Blockage
Inspect vents and fans for dust buildup or obstruction. Ensure adequate airflow around the unit.
Expected Outcome: Overheating conditions resolved; system may boot normally after cooling.
Observe Boot Behavior
Watch for:
- Manufacturer logo appearing and freezing
- Error messages
- Repeated restart cycles
Why it matters: Provides clues to software vs. hardware failure.
Attempt Alternate Power Cycle
If freezing occurs during use, perform a controlled shutdown (if possible), then restart. If unresponsive, perform a forced shutdown and restart once.
Expected Outcome: Temporary software freeze may clear.
Check Battery (If Equipped)
If the unit has an internal battery or UPS function, verify it is not causing startup issues.
Expected Outcome: Faulty battery may prevent proper boot.
If the Problem Persists
If the system still fails to boot or continues freezing after these checks, common external causes have been ruled out. The issue is likely internal (e.g., power supply, motherboard, or storage failure).
Remove the system from service, label it Out of Service, and send for repair or bench evaluation. Proper troubleshooting includes recognizing when escalation is necessary.
Clinical Use Tip
Never troubleshoot boot or freezing issues while the system is connected to a patient. Always transition clinical care to another device before beginning diagnostics.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Ultrasound system would not boot and froze on startup screen."
Cause
What was observed during troubleshooting.
Example:
"System freeze persisted after power reset; no external peripherals connected; likely internal hardware or software fault."
Resolution
What action was taken.
Example:
"Removed from service and sent for further evaluation and repair."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord inspected/replaced
- Indicator lights behavior during startup
- Peripherals disconnected
- Boot screen behavior or error messages
- Fan operation or overheating signs
- Any unusual noises or delays
- Final device status (Out of Service)
Final Thought
System boot failures should always be approached from the outside in—starting with power, connections, and environment. Avoid assuming internal failure too early, but recognize when escalation is appropriate. Patient safety and clear documentation are critical throughout the process.
That is successful troubleshooting.
