What This Guide Helps With
System not powering on, freezing during startup, reboot loops, or crashing during operation due to power, accessory, or software-related issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the system from clinical use if it is unreliable.
- Move the patient to another ultrasound system before troubleshooting.
Expected: No interruption to patient care
Why it matters: Boot failures prevent safe imaging and diagnosis
Verify Power Source and AC Adapter
- Confirm the system is plugged into a known-good outlet.
- Check the AC adapter for:
- Secure connection to the unit
- Indicator lights (if present)
- Damage to cable or brick
Expected: Power indicators illuminate and system attempts to boot
Why it matters: Power supply issues are a common and easily overlooked cause
Check Battery Status (If Equipped)
- Disconnect AC power and attempt to power on using battery only.
- Then reconnect AC and observe charging indicators.
Expected: System powers on or shows charging activity
Why it matters: A failed battery can prevent proper startup or cause instability
Perform a Full Power Cycle
- Shut down the system completely.
- Disconnect AC power and remove battery (if accessible).
- Hold the power button for 10–15 seconds.
- Reconnect power and restart.
Expected: System boots normally if issue was transient
Why it matters: Clears temporary system faults and resets hardware states
Disconnect All External Accessories
- Remove all probes and USB/network devices.
- Attempt to boot the system with no peripherals connected.
Expected: System boots successfully
Why it matters: A faulty probe or accessory can halt or crash the boot process
Test with Known-Good Probe (After Boot)
- If the system boots without accessories, reconnect one known-good probe.
Expected: System remains stable
Why it matters: Identifies whether a specific probe or port is causing crashes
Observe Boot Behavior and Error Messages
- Note where the failure occurs:
- No display at all
- Freezes on logo screen
- Reboots repeatedly
- Displays error messages
Expected: Consistent behavior pattern
Why it matters: Helps determine if issue is power, software, or hardware related
Check for Overheating or Environmental Issues
- Ensure vents are not blocked.
- Check for excessive heat, dust buildup, or fan noise.
Expected: Normal airflow and temperature
Why it matters: Overheating can cause shutdowns or boot instability
Attempt Safe Restart / Software Recovery (If Available)
- If accessible, attempt system recovery or safe startup mode per facility protocol.
Expected: System may recover from software corruption
Why it matters: Software issues are a common cause of boot failure
If the Problem Persists
If the system still fails to boot or continues crashing after completing these steps, common external causes have been ruled out. The issue is likely internal (power supply, motherboard, storage, or system software failure).
Remove the device from service, label it Out of Service, and send it for repair or bench evaluation.
Clinical Use Tip
Never attempt to troubleshoot a booting or crashing ultrasound system while it is needed for an active patient exam. Always transition to a functioning unit first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Ultrasound system would not boot and intermittently restarted during use."
Cause
What was observed during troubleshooting.
Example:
"System failed to boot with accessories connected; issue isolated after removing faulty probe."
Resolution
What action was taken.
Example:
"Removed defective probe from service; system booted normally and returned to operation."
Helpful Details to Include (If Known)
- Outlet tested and verified
- AC adapter condition checked
- Battery behavior observed
- Boot stage where failure occurs
- Accessories removed/tested
- Any error messages displayed
- Presence of heat, noise, or fan issues
- Final system status (working or sent for repair)
Final Thought
Boot failures should always be approached methodically, starting with power and external components before assuming internal failure. Patient safety comes first, and recognizing when escalation is required prevents unnecessary downtime and risk. Proper documentation ensures clarity and supports long-term reliability tracking.
That is successful troubleshooting.
