It is likely that as lower the voltage is, as higher the current consumption is.
The PCH has two I2C signals, they are called SDA and SCL. Those two signals are connected also to the touchfield of the keyboard. And I think, to the BIOS chip, too. For the BIOS chip, you can find the pinout diagram in the internet. Check for the I2C signals, whether there is a good traffic or not. If you do not have an oscilloskope, you can test with a multimeter in voltage mode. The signals are something higher than 0V and lower than 3.3V or 1.8V. If you have continually stable 3.3V (1.8V), then there is...

Hi!
Can you toggle the LED with the CAPS-LOCK or NUM key while the system is booting? Also, try to get into the BIOS while starting ("F2" or "DEL"-key).

Hello, Community!
I ran into a problem with this item:

CLEVO Barebone NH58HPQ - i5-11400H - NVIDIA GeForce RTX 3060

6-77-NH50HP00-D02A-1C#10
6-71-N5HP0-D02A

I've unable to find the boardview of this mainboard.

Thank you very much for your help!
