What This Guide Helps With
EKG not charging, running only on battery, or shutting down due to power source, battery, or connection issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- If the device is in use, transfer the patient to another EKG machine before troubleshooting.
Expected: Patient monitoring continues uninterrupted.
Why it matters: Power loss can interrupt ECG acquisition and documentation.
Verify Wall Outlet Power
- Plug in another device to confirm power
- Try a different outlet if needed
Expected: Outlet provides stable power.
Why it matters: A dead or switched outlet is a common external cause.
Inspect AC Power Cord and Adapter
- Ensure connections are fully seated at both ends
- Look for frayed wires, bent prongs, or loose connectors
- Swap with a known good cord/adapter if available
Expected: Secure, undamaged connection.
Why it matters: Faulty cords or adapters prevent charging.
Confirm AC Power Indicator on Device
- Plug in the device and observe indicator lights
- Power the unit on if possible
Expected: AC indicator is lit and device recognizes external power.
Why it matters: Confirms whether the device is receiving power.
Check Battery Charging Status on Display
- Look for charging symbol or percentage increase
- Note any battery-related warnings or messages
Expected: Battery shows charging status.
Why it matters: Helps determine if the issue is battery vs charging circuit.
Perform a Power Reset
- Power off the unit
- Disconnect AC power
- Wait 30–60 seconds
- Reconnect power and restart
Expected: Charging resumes after reboot.
Why it matters: Temporary faults can prevent charging recognition.
Check for Docking Station or External Charger (If Applicable)
- Ensure the device is properly seated
- Inspect docking contacts for dirt or damage
- Try a different dock if available
Expected: Proper contact allows charging.
Why it matters: Poor contact prevents current flow to the battery.
Inspect for Environmental or Physical Issues
- Check for excessive heat near battery area
- Look for liquid exposure or corrosion
Expected: No abnormal conditions present.
Why it matters: Environmental damage can affect charging circuits.
If the Problem Persists
If all external power sources, cables, and connections have been verified, the issue is likely internal (battery failure, charging circuit, or power board).
Remove the device from service, label it Out of Service, and send it for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and saves troubleshooting time.
Clinical Use Tip
Do not troubleshoot charging issues while the device is actively needed for patient care. Always move the patient to a functioning EKG machine first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"EKG machine not charging and shutting down during use."
Cause
What was observed during troubleshooting.
Example:
"Battery failed to accept charge after verifying power cord, outlet, and adapter were functional."
Resolution
What action was taken.
Example:
"Removed device from service and sent to Clinical Engineering for battery replacement and evaluation."
Helpful Details to Include (If Known)
- Outlet tested and confirmed working
- Power cord and adapter swapped
- AC indicator status observed
- Battery icon behavior noted
- Any warning messages recorded
- Device shuts down on battery
- Final device status (removed from service)
Final Thought
Effective troubleshooting starts with simple external checks and confirms power delivery before assuming internal failure. Patient safety must always come first, and proper escalation ensures reliable equipment performance.
That is successful troubleshooting.
