What This Guide Helps With

Troubleshooting charging failure, short battery runtime, unexpected shutdown, power adapter issues, and external charging-related problems on the Ambu aView 2 Advance.

Step-by-Step Troubleshooting

Ensure Patient Safety First

If the aView 2 Advance is being used for an active procedure, do not troubleshoot the battery or charging issue during patient care.

Move the clinical team to a known-good monitor or alternate visualization system before continuing.

Expected outcome: Patient care continues without relying on a monitor that may shut down unexpectedly.

Why it matters: A sudden monitor shutdown during endoscopy or airway visualization can interrupt clinical workflow and create a patient safety risk.

Confirm the Reported Battery Behavior

Power on the monitor and verify the exact complaint.

Check whether the issue is:

Expected outcome: The failure mode is confirmed before replacing accessories or escalating.

Connect to a Known-Good AC Outlet

Plug the charger into a verified working wall outlet.

Avoid power strips, loose receptacles, switched outlets, or outlets controlled by wall switches.

Expected outcome: The monitor shows charging activity or powers reliably from AC.

If this resolves the issue, stop. The likely cause was outlet or facility power-related.

Inspect the Power Adapter and Charging Cable

Check the AC adapter, power cord, and connector for:

Expected outcome: The charger and cable appear intact and provide stable power.

Why it matters: A damaged charger may power the monitor intermittently but fail to charge the battery correctly.

Use a Known-Good Compatible Charger

If available, connect the aView 2 Advance to a known-good compatible Ambu-approved power supply.

Allow the monitor to remain connected long enough to observe whether the battery icon or charge status changes.

Expected outcome: The monitor begins charging normally.

If this resolves the issue, stop. Remove the failed charger from service and replace it.

Check the Monitor Charging Port

Inspect the charging port without inserting tools or forcing the connector.

Look for:

Expected outcome: The charging port is clean, dry, stable, and accepts the connector securely.

If the port is damaged or loose, remove the monitor from service.

Verify the Monitor Is Fully Seated on External Power

Confirm the power connector is fully inserted and not partially engaged.

Observe whether the charging indicator changes when the connector is gently seated.

Expected outcome: The monitor recognizes external power consistently.

Why it matters: A partially seated connector can mimic a battery or internal charging failure.

Allow a Depleted Battery Recovery Period

If the monitor battery is fully depleted, leave it connected to a known-good power source for a reasonable charging period before retesting.

Then attempt to power the unit on while still connected to AC.

Expected outcome: The monitor powers on and shows charging progress.

If the monitor remains dead or does not recognize charging, continue troubleshooting.

Check for Rapid Shutdown After Charging

After the monitor has charged, disconnect AC power and observe runtime behavior.

Confirm whether the battery percentage drops abnormally fast or the monitor shuts down shortly after unplugging.

Expected outcome: Battery runtime is stable enough for normal clinical use.

If the monitor shuts down quickly after charging, suspect battery degradation or internal power management failure.

Check for Overheating, Odor, or Battery Swelling Signs

Inspect the monitor exterior for abnormal heat, odor, case distortion, swelling, or unusual display behavior during charging.

Expected outcome: The unit remains physically normal during charging.

If heat, odor, swelling, or case distortion is present, disconnect power immediately and remove the device from service.

Perform a Power Cycle

With the monitor disconnected from accessories, power the unit off completely, reconnect AC power, and power it back on.

Observe whether charging status returns to normal.

Expected outcome: A temporary software or power-state issue clears.

If this resolves the issue, monitor the unit long enough to confirm stable charging before returning it to service.

Check for Accessory or Peripheral Influence

Disconnect any attached endoscope, USB device, external media, or nonessential accessory.

Retest charging and battery runtime with only the monitor and charger connected.

Expected outcome: Charging behavior remains stable without accessories attached.

Why it matters: A connected accessory or port issue may increase power draw or interfere with normal operation.

Review Battery Age and Usage History

Check service history, prior work orders, and user reports for repeated short-runtime complaints.

Look for patterns such as:

Expected outcome: History supports whether this is a one-time external issue or a recurring battery/internal power fault.

Perform Facility-Approved Functional Verification

If the monitor charges normally after external checks, perform a basic operational check per facility process.

Confirm:

Expected outcome: The monitor is safe to return to service if all checks pass.

If the Problem Persists

If the Ambu aView 2 Advance still will not charge, only operates on AC power, shuts down quickly after charging, has a damaged charging port, or shows abnormal heat or odor, common external causes have been ruled out.

The device should be:

At this point, the likely cause may involve the internal battery, charging circuit, power input board, or internal power-management components.

Knowing when to stop is proper troubleshooting. Clinical Engineering should not continue using or returning a monitor with unreliable battery performance.

Clinical Use Tip

Do not troubleshoot charging or battery runtime problems during an active procedure. If the monitor may shut down unexpectedly, replace it with a known-good unit before continuing patient care.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported that the Ambu aView 2 Advance would not hold a charge and powered off shortly after being unplugged."

Cause

What was observed during troubleshooting.

Example:
"Verified outlet and charger were functional, but the monitor battery percentage dropped rapidly after charging and the unit shut down during battery operation."

Resolution

What action was taken.

Example:
"Removed the monitor from service, labeled it Out of Service, and sent it for bench evaluation due to suspected internal battery or charging-system failure."

Helpful Details to Include (If Known)

Final Thought

Battery and charging issues on an endoscopy monitor should be handled carefully because unexpected shutdown can interrupt visualization during patient care. Start with outlet, charger, cable, and port checks before suspecting internal failure. If the monitor cannot reliably charge or maintain power, remove it from service and document the complaint, cause, and resolution clearly.

That is successful troubleshooting.
