Overview:
Power-on self-start, also known as Auto Power On, describes a feature found in industrial motherboards or computers where the system automatically powers on once the power supply is activated, initiating system startup.
Why do industrial motherboards or computers have this feature?
Industrial control motherboards or computers are commonly deployed in unattended environments such as vending machines, express cabinets, advertising displays, production lines, processing equipment, traffic control systems, security surveillance, healthcare facilities, and banking equipment. In such scenarios, there is typically no dedicated personnel for maintenance or oversight of power switches. Power switches are primarily used for toggling equipment power on or off. In such cases, the power-on self-start advantage of industrial computers proves invaluable. Upon power activation, the industrial control motherboard or computer autonomously detects the power supply and automatically powers on and starts functioning. Next, we will introduce the setup method for the K4 model.
The power-on self-start function of industrial control motherboards or industrial control computers is broadly categorized into the following two methods:
a. Dedicated circuit board design: This type of motherboard typically features an independent 3-pin connector labeled PWRON1. By default, a jumper cap is installed across pins 1 and 2. When these pins are shorted in the off state, the power remains off. However, moving the jumper cap to connect pins 2 and 3 in the open state results in automatic power-on.
(Advantage of this method: Adjusting the jumper cap ensures stable operation, independent of BIOS control. This method remains effective even if BIOS settings are restored to default or the CMOS battery power is low.)
b. BIOS (CMOS) configuration: This method involves accessing the BIOS to modify CMOS parameters.
(Advantage of this method: No need to dismantle the machine; CMOS parameters can be directly modified within the BIOS.)
Applicable models:
H2-i3-4010Y, i5-4200u, i7-4500u, H2-5th Gen.
Press the PC switch button and then quickly hit the keyboard Delete/Del key to enter the BIOS Setup, in turn, select Chipset>PCH-IO Configuration>Restore AC Power Loss set to Power on, after successful setup, press the keyboard F10 key to save and exit or select Save & Exit>Save Changes and Exit.
Applicable models:
H2-7th Gen,8th Gen
Remove the 4 screws and open the chassis, find the PWRON1 pin on the motherboard, move the jump cap on the PWRON1 pin to pin2 and pin3 to enable the Auto Power on function.
(Warm tips: Please disconnect the power before operation, such as power operation may lead to the motherboard into a protective state, serious damage to the motherboard!)
