Powering Intelligence at the Edge

Verify the system BIOS date and time settings. An incorrect RTC/BIOS clock may cause package signature validation, SSL certificate verification, and GNOME service initialization failures, resulting in the installer appearing to hang during package configuration.

On Windows systems, the ignition shutdown behavior is linked to the system power button action.

To allow the system to perform a graceful shutdown when IGN is turned off, please configure the Windows power button behavior as Shut down.

Steps:

1. Open Control Panel.
2. Go to Power Options.
3. Select Choose what the power buttons do.
4. Set When I press the power button to Shut down.
5. Save the changes.

When the IGN signal is turned off, the system will trigger the configured power button action and allow Windows to perform a normal shutdown process.

Note:
If the power button action is set to Sleep, Hibernate, or Do nothing, the system may not shut down properly when IGN is turned off.

IGN Only Mode is designed to keep the system power behavior controlled by the ignition signal.

When the system is shut down by software, the system may enter a standby state instead of being completely powered off.

If IGN Only Mode is enabled and the IGN signal remains active, the system will automatically power on again within a few seconds after software shutdown.

This behavior ensures that the system stays powered on as long as the vehicle ignition signal is present.

SINTRONES platforms support automatic system startup after external power is restored.

To configure this feature:

1. Enter the BIOS Setup Utility.
2. Navigate to:
   Advanced → AC Power Loss
3. Select the desired behavior:
   • Power Off – The system remains powered off after power is restored.
   • Power On – The system automatically powers on when power is restored.
   • Last State – The system returns to its previous power state before power loss.
4. Save the BIOS settings and reboot the system.

Note:
1. The available options and menu locations may vary depending on the platform model and BIOS version. Please refer to the product user manual for detailed instructions.

2. For platforms equipped with Ignition Power Management, the IGN signal must remain active (IGN ON) for the system to power on successfully after AC power is restored.

If the IGN signal is not present, the system may remain in the power-off state even when AC Power Loss is configured as Power On.

Please ensure that both the external power source and IGN signal are available when using the automatic startup function.

Common diagnostic tools include:

Providing logs can significantly speed up troubleshooting.

Secure Boot only allows digitally signed bootloaders and operating systems to start.

If the USB installer contains:

• Unsigned bootloaders
• Custom Linux distributions
• Modified Windows PE images

the system may block the boot process.

In such cases, try:

• Using a Secure Boot compatible installation image.
• Temporarily disabling Secure Boot.
• Verifying that the installation media was created correctly.

The BIOS version information can be viewed during system startup or from the BIOS Setup Utility, as shown in the screen below.

To help us investigate efficiently, please provide:

• Product Model
• Serial Number
• BIOS Version
• Operating System Version
• Problem Description
• Photos or Videos (if available)

The product model name and serial number can be found on the product label attached to the chassis.

Secure Boot and TPM (Trusted Platform Module) are different security technologies.

Secure Boot

• Protects the boot process.
• Verifies the authenticity of bootloaders and operating systems.

TPM

• Provides hardware-based security functions.
• Stores encryption keys and certificates securely.
• Supports features such as BitLocker and device attestation.

Many SINTRONES platforms support both Secure Boot and TPM 2.0 for enhanced system security.
