1) The indicator light at the lower right corner of the machine is not on, why?

• Check whether the indicator of the power adapter is on;
• If the indicator is faulty, check whether the external AC power socket has power;
• Check whether the DCIN plug of the I/O panel falls off;
• Replace the power adapter with the same voltage and wattage to test;
• The mainboard or internal circuit of the machine is faulty , please contact the local service provider for repairs.

2) The indicator light in the lower right corner of the machine screen turns blue, but there is no image when you press the power button. Why?

• Note whether there is a "di-di-di" alarm when booting. If there is, please turn to a professional to reinstall the memory or replace the memory to test;
• If there is no any alarm sound, check whether the power button is damaged. The test can be carried out by short circuiting the power pins in the mainboard.
• The mainboard or its internal circuit is faulty, please contact the local service provider for repairs.

3) The machine is completely unresponsive to touch, why?

• After logging into the system, check Control Panel -- to see whether there is a Tablet Setting option under Hardware and Sound. If you can find the tablet touch option, open it and test the touch screen by following the steps afterwards, and then calibrate the touch screen with the 4 corners;
• If the problem cannot be solved by the steps above, replace the touch controller or touch panel by reference to the disassembly and installation guide and it should be solved.

4) There is no display with the optional VGA cable for the secondary screen from Elanda, why?

• Check whether the VGA cable and DC power cable on the secondary screen are connected or locked.
• If the display still shows no image after step A, connect it to a standard VGA monitor to test. If the it still fails after switching to another VGA monitor, the VGA port on the mainboard is faulty, and you can contact the local service provider for repairs.
