(Sorry for my English, I use a translator)
The triangle appears only when I connect the power supply for the first time and disappears when I turn on the computer. I usually turn off the power supply when I go away.
When I turn off the system (Windows) without disconnecting the power supply the triangle does not appear (the ASUS logo in the database stays on). I only get the triangle when I go back and connect the power supply.
I have also seen that the triangle only appears at that point if I connect the USB that comes from the LCD screen (attached image).
The lights and display work correctly when the computer is on using the ICUE.
Thank you very much for replying! best regards and happy new year!
