Depending on the brand and specifications of the hard drive, SSD information may sometimes not be correctly detected in the BIOS. Please follow the steps below to configure your SSD in the BIOS.

Check the SATA mode AHCI/RAID/IDE and SATA Gen Speed.

Press “del” into the BIOS in boot stage and set the SATA mode to AHCI

Chipset -> PCH-IO Configuration -> SATA And RST Configuration -> SATA mode Selection -> AHCI.

Chipset -> PCH-IO Configuration -> SATA And RST Configuration -> SATA Controller Speed ->Gen 1. 2. 3. (base on your SATA Gen requirement)

Sintrones offers various series of hardware platforms tailored to different environmental application requirements. You can refer to the following memory support list to meet your needs.

Based on some customized requirements, the system needs a BIOS update to achieve the desired hardware environment for the customer. This article primarily guides customers on how to update their system's BIOS. For detailed steps, please refer to the attached SOP.

1. Check voltage of power supply, please refer to manual to check suitable watt of power supply for your model.
2. Check whether CPU and memory has been installed properly.
3. Switch another good memory then try again.
4. Reset MCU: plug in DC, keep IGN off, press and hold power button for 15 seconds until ACC light blinking.
5. If steps above can’s solve problem, record the status of power button then report to technical support team.

Status of power button list as below:

• Does power button is light or not?
• Does power button is blink or keep bright?
• What color of power button? Red or blue?

The CMOS battery, also known as the Complementary Metal-Oxide Semiconductor battery, is a small battery found on most modern motherboards. It provides a small amount of power to the computer’s basic input/output system (BIOS) in order to keep it functioning and maintain any settings that are stored within the BIOS, such as the computer’s time and date.If the battery's voltage output is less than 2.3V, please change a new one battery on the motherboard.

You can refer to the following pics to check the CMOS battery Voltage.

Red wire = V+

Black wire = V-

Sintrones' products are primarily designed for use in vehicle computers. Therefore, we have specifically provided an ignition switch on our products to power on or off your vehicle computer. Please refer to the following ignition connection instructions.

Ignition Power Management Quick Guide

Startup/shutdown conditions from the IGNITION signal:
◆ IGNITION startup signal must be valid during 3 sec. (anti-noise protection).
◆ IGNITION shutdown – IGNITION signal must be inactive during 3 Sec, then PIC
controller initiate Power Button signal (OS must be set to shut down from the
Power Button). It generate Main Button shutdown event and then goes to
complete power off.

Typically the system can start only from IGNITION signal, because startup PIC controller
is disconnected from the power source.
The system can be switched off from:
◆ Power IGNITION OFF signal.
◆ ACPI OS shutdown
◆ Power Button – generate ACPI event (OS dependent)
