What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting situations where a Fujifilm Sonosite Edge II battery is not charging properly or has reduced runtime. Common symptoms include:
- Battery indicator not increasing while plugged in
- System only functioning on AC power
- Rapid battery depletion after disconnecting from AC
- Device not recognizing the battery or showing charging errors
The guide focuses on simple external checks before assuming internal battery or board failure.
Step-by-Step Troubleshooting
Verify AC Power Source
- Ensure the system is plugged into a known working outlet.
- Test the outlet with another device or a voltmeter.
- Reason: A faulty outlet or power strip is a common cause of battery not charging.
Check Power Cord and Adapter
- Inspect the power cord for cuts, frays, or bent connectors.
- Confirm the AC adapter matches the specifications for the Edge II.
- Swap with a known-good cord/adapter if available.
- Reason: Damaged cords or incorrect adapters prevent proper charging.
Confirm Battery Seating
- Remove and reseat the battery in the device.
- Ensure the battery clicks fully into place and terminals align correctly.
- Reason: Poor contact can prevent charging or cause intermittent detection.
Inspect Battery for Damage
- Look for swelling, leaks, corrosion, or unusual heat.
- Reason: Physical damage indicates the battery should be removed from service.
Observe System Indicators
- Check the on-screen battery icon or LEDs.
- Note any error codes or messages displayed when connected to AC.
- Reason: System diagnostics may identify whether the issue is the battery or device circuitry.
Test with a Known-Good Battery
- If available, insert a different, fully charged Edge II battery.
- Observe if it charges normally.
- Reason: Confirms whether the issue is with the battery or the system.
Power Cycle the System
- Shut down the ultrasound, remove AC power and battery, wait 1–2 minutes, then reconnect and power on.
- Reason: Resets charging circuitry and clears minor firmware glitches.
If the Problem Persists
External causes (outlet, cord, adapter, battery seating) have been ruled out. The internal charging circuit or battery management system may be faulty.
- Remove the device from service
- Label it Out of Service
- Send for vendor repair or bench evaluation
Knowing when to stop prevents unsafe troubleshooting and protects patient care.
Clinical Use Tip
Do not attempt battery charging troubleshooting while the device is connected to an active patient.
If patient imaging is required, move the patient to another operational ultrasound system first.
Only perform troubleshooting in a safe environment where patient care is not impacted.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Battery not charging, system only works on AC power.”
Cause
What was observed during troubleshooting.
Example:
Observed that the AC outlet and adapter are functioning, battery seated correctly, but the system does not charge. Battery indicator remains static.
Resolution
What action was taken.
Example:
Removed device from service, labeled Out of Service, and sent for repair evaluation.
Helpful Details to Include
- AC outlet tested: Yes
- Power cord swapped: Yes
- Battery inspected: Yes, no visible damage
- Battery indicator behavior: Static
- Device temperature normal: Yes
- Error messages observed: None or specific battery alert
- Final device status: Out of Service
Final Thought
Battery issues in portable ultrasound systems can appear minor but may compromise system readiness. Logical troubleshooting and early escalation protect patient safety and reduce risk. Accurate CCR documentation ensures clear communication and supports future maintenance decisions.
That is successful troubleshooting.
