What This Guide Helps With
Troubleshooting charging problems, short battery operation, lost bed functions, power-source issues, damaged cords, connections, controls, or an aged battery.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Continuity of Care
Do not troubleshoot unreliable backup power while a patient depends on the bed for positioning, alarms, transport, or emergency functions.
Notify the responsible clinical staff.
Connect the bed to a verified AC source when safe.
Transfer the patient to another verified bed if dependable powered operation cannot be maintained.
Keep the bed brakes set and the bed in a safe position.
Do not transport the patient relying on an unverified battery.
Expected outcome: The patient remains supported by a bed with dependable power and positioning functions.
If reliable operation cannot be maintained, remove the bed from clinical use and troubleshooting can stop.
2. Confirm the Exact Reported Condition
Determine whether the bed:
Does not indicate charging while connected to AC power.
Operates normally on AC but loses all functions when unplugged.
Operates on battery briefly and then stops.
Loses only selected functions on battery.
Displays a battery, power, or service indication.
Has been stored unplugged or recently returned from transport.
Record the condition before cycling power or reconnecting accessories.
Expected outcome: The failure is clearly identified as a charging, battery-runtime, power-input, or function-specific problem.
3. Inspect the Power Cord and Plug
Disconnect the bed from AC power and inspect the accessible power cord, plug, strain relief, and cord storage area.
Look for:
- Cuts, crushing, exposed conductors, or melted insulation.
- Bent, loose, burned, or contaminated plug blades.
- Damage where the cord enters the bed.
- A cord that has been pulled tightly, rolled over, or pinched by the frame.
- Evidence of fluid intrusion, overheating, or an unusual odor.
Do not continue using a damaged power cord.
Expected outcome: The power cord and plug are intact, clean, securely attached, and safe to energize.
If damage is found, remove the bed from service and troubleshooting can stop.
4. Verify the AC Power Source
Connect the bed directly to a known-good hospital-grade receptacle.
Avoid extension cords and unverified power strips.
Confirm the receptacle supports another suitable test device or is verified with approved electrical test equipment.
Confirm that the plug remains fully seated.
Observe whether AC power and charging indications respond normally.
Expected outcome: The bed recognizes a verified AC source and begins normal charging behavior.
If the bed charges normally from the known-good outlet, correct or report the original receptacle or infrastructure problem. Troubleshooting can stop after functional verification.
5. Allow Adequate Charging Opportunity
If the bed has been stored unplugged, recently transported, or deeply discharged:
Leave it connected to a verified AC source.
Confirm that the bed remains plugged in continuously during evaluation.
Observe whether the battery or charging indication changes over time.
Do not judge battery condition from only a brief connection to AC power.
Do not invent or assume a charging time. Follow current Hillrom documentation when a specified charge period is required.
Expected outcome: Charging indications remain stable and available battery operation improves after an appropriate charging period.
If normal battery operation returns and all required functions pass testing, troubleshooting can stop.
6. Check Accessible Power and Battery Controls
Inspect any externally accessible power switches, battery-enable controls, or removable battery connections provided for normal service access.
Confirm switches are in the required operating position.
Verify that accessible connectors are fully seated.
Look for looseness, corrosion, contamination, bent contacts, or damaged retaining features.
Do not open sealed battery assemblies or bypass protective circuits.
Do not access internal boards or perform deep disassembly.
Expected outcome: All accessible power and battery controls are correctly positioned, and external connections are secure and undamaged.
If reseating an approved accessible connection restores charging, proceed to final functional verification.
7. Compare AC and Battery Operation
With the bed unoccupied and positioned safely:
Connect the bed to verified AC power.
Test basic frame functions and controls.
Confirm normal AC operation.
Disconnect AC power.
Observe the transition to battery operation.
Test only the functions intended to operate on backup power.
Note whether:
- The bed shuts down immediately.
- Functions begin and then stop under load.
- Only one control station is affected.
- Indicators dim, reset, or behave intermittently.
- Reconnecting AC immediately restores operation.
Expected outcome: The bed transitions to battery operation without an unexpected reset and performs its intended backup-power functions consistently.
If operation is stable and repeatable, troubleshooting can stop after final verification.
8. Rule Out a Control or Function-Specific Problem
A reported battery problem may actually be an unrelated control, lockout, actuator, or accessory fault.
Test the same function from another available caregiver control.
Verify that motion lockouts are not active.
Check whether the affected function also fails on AC power.
Disconnect only approved external accessories that may be loading the system.
Compare operation with a known-good compatible pendant or control accessory when permitted.
Expected outcome: The failure is correctly isolated to battery operation rather than a specific control, accessory, lockout, or mechanical function.
If the function works normally after correcting the external control or accessory issue, troubleshooting can stop.
9. Inspect for Conditions That Increase Battery Load
Check for external conditions that may cause excessive demand or repeated operation.
A control button held continuously.
A damaged pendant activating commands intermittently.
An accessory connected to an auxiliary power point.
Repeated actuator cycling during testing or transport.
A frame component obstructed by bedding, equipment, cables, or the environment.
Indicators or accessories remaining active unexpectedly.
Expected outcome: No external control, obstruction, or accessory is causing abnormal power demand.
If removing the external load restores dependable battery operation, document the cause and proceed to final verification.
10. Perform Final Functional Verification
After any correction:
Confirm stable operation on verified AC power.
Confirm that charging indications are normal.
Disconnect AC and verify intended backup-power functions.
Operate representative frame movements without a patient.
Confirm controls, indicators, brakes, steering, alarms, and emergency functions relevant to safe use.
Reconnect AC and verify that charging resumes.
Complete electrical safety testing when required by facility policy or after power-system repair.
Expected outcome: The bed operates safely on AC, transitions correctly to battery power, performs intended backup functions, and resumes charging when reconnected.
If all required checks pass, return the bed to service and troubleshooting can stop.
If the Problem Persists
Common external causes such as the receptacle, power cord, plug seating, accessible controls, charging opportunity, accessories, lockouts, and abnormal external loads have been ruled out.
The remaining problem may involve an aged battery, charging circuitry, internal power connections, power conversion components, configuration, or another service-level fault.
The bed should be:
- Removed from service.
- Labeled Out of Service.
- Sent for repair or bench evaluation.
- Evaluated using current Hillrom documentation and approved test equipment.
- Repaired, configured, or battery-tested only by qualified personnel.
Do not replace internal components based only on the symptom. After repair, perform complete functional, battery-operation, charging, alarm, and electrical safety verification before return to service.
Knowing when to stop external troubleshooting and escalate an unreliable power system is proper troubleshooting.
Clinical Use Tip
Do not use an unverified VersaCare battery as the primary power source during patient transport or during any situation requiring dependable powered positioning.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
