What This Guide Helps With
Troubleshooting charging failure, rapid battery drain, or inability to maintain battery power during portable ultrasound use.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the system from active patient use before troubleshooting battery or power issues.
- If needed, move the patient to another ultrasound system.
Expected: Device is not supporting active care.
Why it matters: Loss of power during imaging can interrupt diagnostics and workflow.
Verify the Reported Issue
- Power on the system and observe battery status indicators.
- Check if the unit:
- Does not charge when plugged in
- Shows low battery despite being connected
- Has significantly reduced runtime
Expected: Issue is clearly reproducible.
Why it matters: Confirms a true power issue vs. user perception or workflow timing.
Check AC Power Source
- Ensure the system is plugged into a known working outlet.
- Test the outlet using another device if needed.
Expected: Outlet provides stable power.
Why it matters: Eliminates facility power issues before focusing on the device.
Inspect Power Cord and Adapter
- Check the AC power cord and external power supply (brick) for:
- Loose connections
- Frayed or damaged cable
- Indicator light on the power supply (if present)
- Reseat all connections securely.
Expected: Power supply is intact and properly connected.
Why it matters: Faulty cords or adapters are a common cause of charging failure.
Confirm Charging Indicator on System
- Observe the CX50 charging indicator (icon or LED).
- Does it show charging when plugged in?
- Does the indicator flicker or not appear?
Expected: Charging indicator activates when connected to AC power.
Why it matters: Helps determine if the system recognizes incoming power.
Check Battery Seating (If Accessible)
- If the CX50 battery is user-accessible:
- Power down the unit
- Remove and reseat the battery securely
- Inspect for:
- Dirt or debris on contacts
- Signs of swelling or damage
Expected: Battery is properly seated with clean contacts.
Why it matters: Poor connection can prevent charging or cause intermittent runtime.
Test Runtime on Battery Only
- Disconnect AC power and operate the system on battery.
- Observe how long it runs before shutting down.
Expected: Battery provides reasonable runtime (based on age/use).
Why it matters: Helps determine if the issue is charging-related or battery capacity degradation.
Evaluate Battery Age and Usage
- Check maintenance records or labeling for battery age.
- Typical lifespan is ~2–3 years depending on usage.
Expected: Older batteries may show reduced capacity.
Why it matters: Natural battery wear is a common cause of shortened runtime.
Perform System Restart
- Power cycle the system completely:
- Shut down
- Disconnect from AC
- Wait 30 seconds
- Restart and reconnect power
Expected: Charging behavior resets if caused by a temporary fault.
Why it matters: Clears minor system or charging control glitches.
If the Problem Persists
If all external causes have been ruled out, the issue is likely internal (battery failure, charging circuit, or power board).
- Remove the system from service
- Label as Out of Service
- Send for repair or bench evaluation
Knowing when to stop prevents unnecessary risk and saves time.
Clinical Use Tip
Do not rely on battery operation for critical imaging if charging behavior is inconsistent. Always verify AC power during patient exams.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"CX50 ultrasound battery not charging and losing power quickly during portable use."
Cause
What was observed during troubleshooting.
Example:
"Battery found to have degraded capacity with no charge retention despite proper AC power and connections."
Resolution
What action was taken.
Example:
"Removed from service and battery replaced; system tested and confirmed normal charging and runtime."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord and adapter inspected
- Charging indicator behavior observed
- Battery reseated or inspected
- Runtime test results
- Battery age (if known)
- Final device status
Final Thought
Battery and charging issues are often external or wear-related. Start with power source and connections, then evaluate battery condition before escalating. Always prioritize patient safety and proper documentation.
That is successful troubleshooting.
