What This Guide Helps With
Troubleshooting battery charging, power-on failure, short runtime, or charger-related issues on a Caresono PadScan HD bladder scanner.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Do not troubleshoot the bladder scanner during active patient care if the scan is needed immediately.
Action:
- Use another bladder scanner or approved clinical assessment method if the device will not power on, has low battery, or cannot complete a scan.
Expected outcome:
Patient care continues without relying on a scanner with uncertain power reliability.
Why it matters:
A bladder scanner with unstable power may shut down during scanning or provide incomplete clinical information.
Verify the Reported Power Issue
Confirm exactly what staff are reporting.
Action:
- Ask or observe whether the issue is unit will not power on.
- Ask or observe whether the issue is battery will not charge.
- Ask or observe whether the issue is battery drains quickly.
- Ask or observe whether the issue is charging indicator does not appear.
- Ask or observe whether the issue is unit powers off during use.
- Ask or observe whether the issue is charger or dock appears damaged.
- Ask or observe whether the issue is display flickers, freezes, or shuts down.
Expected outcome:
The problem is narrowed to a charging issue, battery runtime issue, power adapter issue, or device power failure.
Check the Wall Outlet
Start with the simplest external power source.
Action:
- Plug another known-working device into the same outlet, or test the PadScan charger on a known-good outlet.
Expected outcome:
If the charger begins working on another outlet, the issue is with the original outlet or power strip, not the bladder scanner.
If resolved:
Return the device to service only after confirming normal charging and power-on behavior.
Inspect the Power Adapter and Cord
A damaged charger can prevent battery charging or cause intermittent power.
Action:
- Inspect the charger, power cord, and plug for bent prongs.
- Inspect the charger, power cord, and plug for frayed insulation.
- Inspect the charger, power cord, and plug for loose connector.
- Inspect the charger, power cord, and plug for crushed cable.
- Inspect the charger, power cord, and plug for exposed wire.
- Inspect the charger, power cord, and plug for burn marks.
- Inspect the charger, power cord, and plug for unusual heat.
- Inspect the charger, power cord, and plug for chemical or fluid contamination.
Expected outcome:
The charger and cable should be physically intact with no signs of overheating or damage.
If damage is found:
Remove the charger from service and replace it with the correct approved charger.
Confirm the Correct Charger Is Being Used
Bladder scanners may physically accept similar-looking chargers that are not electrically correct.
Action:
- Verify that the power adapter matches the PadScan HD Series charging requirements and is the facility-approved charger for this device.
Expected outcome:
The scanner is connected to the correct charger.
If the wrong charger is found:
Remove the incorrect charger, connect the correct charger, and retest charging.
Check the Charging Port or Dock Contacts
Poor contact can prevent charging even when the charger is good.
Action:
- Inspect the scanner charging port, docking contacts, or cradle contacts if applicable.
- Look for debris.
- Look for bent pins.
- Look for liquid residue.
- Look for corrosion.
- Look for loose fit.
- Look for cracked plastic.
- Look for charger not seating fully.
Expected outcome:
The charger or dock should connect securely without looseness or visible contact damage.
If debris is present:
Clean only according to facility-approved external cleaning practices. Do not scrape contacts aggressively or disassemble the unit.
Reseat the Scanner on the Charger or Dock
Charging issues are sometimes caused by poor seating.
Action:
- Place the scanner firmly on the charging dock or reconnect the charging plug.
- Confirm that the scanner is seated correctly and not tilted or partially connected.
Expected outcome:
The charging indicator should appear, or the device should show that external power is connected.
If resolved:
Allow the scanner to charge, then verify normal startup and battery status before returning it to service.
Allow Time for a Deeply Discharged Battery
A fully depleted battery may not power the scanner immediately.
Action:
- Leave the scanner connected to the correct charger for an appropriate charging period.
- Then attempt to power it on again.
Expected outcome:
The display, charging indicator, or power LED should respond after the battery recovers enough charge.
If there is still no response:
Continue troubleshooting external power components before assuming internal failure.
Check for Battery Runtime Problems
If the scanner charges but dies quickly, the battery may be weak or near end of life.
Action:
- Fully charge the scanner, then monitor whether it powers on normally and holds charge during typical use.
Expected outcome:
The scanner should remain powered long enough for normal clinical scanning activity.
If runtime is poor:
Remove the device from service for battery evaluation or replacement according to facility process.
Observe for Abnormal Heat, Smell, or Swelling
Battery and charging issues require caution.
Action:
- Check the scanner, battery area, charger, and dock for unusual heat.
- Check the scanner, battery area, charger, and dock for burning smell.
- Check the scanner, battery area, charger, and dock for swollen case.
- Check the scanner, battery area, charger, and dock for deformed battery cover.
- Check the scanner, battery area, charger, and dock for melted plastic.
- Check the scanner, battery area, charger, and dock for crackling sound.
- Check the scanner, battery area, charger, and dock for intermittent power cycling.
Expected outcome:
The device and charger should remain cool to mildly warm with no odor, swelling, or damage.
If any abnormal condition is found:
Stop troubleshooting, unplug the charger if safe, remove the device from service, and escalate for repair.
Perform a Controlled Power Restart
If the device powers on but behaves inconsistently, a restart may clear a temporary software or power-state issue.
Action:
- Power the scanner off, disconnect it from external power, wait briefly, reconnect to the charger, and power it back on.
Expected outcome:
The scanner should boot normally and display battery or charging status.
If resolved:
Confirm the device completes startup and is able to perform a basic readiness check before returning it to service.
Check for Recurring Power Failure
Intermittent shutdowns should not be ignored.
Action:
- Gently move the device and charger cable while connected.
- Do not stress the connector.
- Observe whether the charging status drops out or the device powers off.
Expected outcome:
Charging and power status should remain stable.
If power cuts in and out:
Suspect a loose charging port, damaged cable, failing dock, or internal power connection. Remove from service.
If the Problem Persists
If the PadScan HD Series bladder scanner still will not charge, will not power on, powers off unexpectedly, or has unreliable battery runtime after external checks, common external causes have been ruled out.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair, battery evaluation, charger replacement, or bench inspection
Do not continue swapping parts or repeatedly attempting to charge a device that shows heat, odor, swelling, damaged contacts, or intermittent power failure.
Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Do not troubleshoot a bladder scanner power problem while staff are waiting to scan a patient. Provide a backup scanner first, then evaluate the failed device away from patient care. A bladder scanner with unreliable power should not be used for patient decisions until it is confirmed stable.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported the Caresono PadScan HD bladder scanner would not power on and did not appear to charge when placed on the charger."
Cause

Final Thought
Battery and power issues should be handled carefully because they can interrupt patient care and may indicate charger, dock, battery, or internal power problems. Start with outlet, charger, dock, and contact checks before assuming device failure. If the scanner remains unreliable, remove it from service and document the complaint, cause, and resolution clearly.
That is successful troubleshooting.
