What This Guide Helps With
Identifies causes of battery not charging, device not powering on, or intermittent power loss due to external power, charger, or connection issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm the device is not in use on a patient.
- Move testing to another spirometer if needed.
Verify Power Symptoms
- Confirm the exact issue:
- Device will not power on
- Battery not charging
- Intermittent shutdown
- Attempt to power on with and without charger connected.
Check AC Power Source
- Verify outlet functionality using a known working device.
- Ensure power strip (if used) is ON.
Inspect Power Adapter and Cable
- Check charger for:
- Loose connections
- Frayed or damaged cable
- Bent or worn connector
- Ensure correct manufacturer-approved adapter is being used.
Confirm Charging Indicators
- Connect charger and observe device indicators:
- Charging light or icon present
- No light or indication
- Gently move the connector to check for intermittent contact.
Attempt Power-On While Plugged In
- With charger connected, attempt to power on device.
- Powers on → likely battery degradation issue
- Does not power on → possible charger or internal power circuit issue
Allow Charging Time and Recheck
- Leave device connected for at least 15–30 minutes.
- Attempt power on again.
Check for Environmental or Usage Factors
- Confirm:
- Device not exposed to extreme temperatures
- Charging contacts are clean and dry
- No recent liquid exposure
Perform Controlled Restart (If Device Powers On)
- If device powers on intermittently:
- Power off completely
- Restart after a brief pause
If the Problem Persists
If all external power sources, adapters, and connections have been verified and the device still does not charge or power on, the issue is likely internal (battery failure or charging circuitry).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and is part of proper troubleshooting.
Clinical Use Tip
Do not attempt to troubleshoot charging or power issues while the device is connected to a patient. 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:
"Device reported not charging and unable to power on during use."
Cause
What was observed during troubleshooting.
Example:
"Failed battery or charging circuit suspected after verifying outlet, adapter, and cable were functional."
Resolution
What action was taken.
Example:
"Removed device from service and sent to Clinical Engineering for further evaluation and repair."
Helpful Details to Include (If Known)
- Outlet tested and confirmed working
- Alternate charger tested (if available)
- Charging indicator behavior
- Device powers on with AC only vs not at all
- Condition of charging port and cable
- Any signs of heat, damage, or liquid exposure
- Final device status (removed from service)
Final Thought
Power-related issues should always be approached from the outside in. Verifying power sources and accessories first prevents unnecessary escalation. When external causes are ruled out, timely removal from service protects both patient safety and equipment reliability. Proper documentation ensures clear communication and efficient follow-up.
That is successful troubleshooting.
