Battery handling
When the Rugged Industrial PC is not connected to external power it runs on battery
power.
An internal bridge battery will keep the Rugged Industrial PC running during battery
replacement.

The red status LED will start to flash when the Rugged Industrial PC battery is running
low. The operating system will also show the Shut Down Windows dialog box.
When the dialog appears select Cancel and continue to work, change the battery or
connect to external power. The system will repeat to display the Shut Down Windows
dialog every 60-70 seconds.
When the battery is running critically low the system will send a sleep signal to the
operating system. This is repeated every 30-40 seconds. The action of the sleep signal
is described in the chapter “ Power settings” on page 7.
