How Do ELO Displays Handle Power Failures

Built-In Protection

ELO Android and Windows systems use flash storage with journaling file systems. When power cuts, incomplete data writes roll back automatically at the next boot.
Voltage regulators smooth sudden drops, keeping logic circuits stable long enough to finish shutdown processes.

Using Backup Power

Install a small uninterruptible power supply (UPS) per kiosk or group of screens. Even five minutes of backup time allows controlled shutdown and prevents corruption.
Choose line-interactive UPS models that regulate voltage rather than simple surge protectors.

Automatic Restart

ELOView supports power-on scheduling. When electricity returns, devices boot automatically and launch assigned apps.
Set a short startup delay for networks that take longer to reconnect, ensuring cloud content loads correctly.

Data and Application Recovery

Transaction or log data should sync to cloud servers every few minutes. This guarantees that the next reboot resumes from the latest saved state.
Avoid local-only databases for critical workflows.

Preventive Maintenance

Check UPS batteries annually and replace them every three years.
Ensure all power cables fit snugly to avoid arcing during surges.

Example

A chain of grocery self-checkout kiosks experienced regional blackouts. Each ELO unit had a 10-minute UPS. The moment power returned, systems rebooted automatically and resumed service within two minutes. No customer data was lost.

Final Thoughts

Power interruptions do not have to mean downtime. With proper backup power, automatic restart, and cloud synchronization, ELO kiosks recover gracefully.
