What do the colors of the LED light stand for?

#1
The LED light in the front of the NEO Z83-4 box has 4 different color indication.

Blue: The power adapter supplies power to the motherboard (PCBA) normally.

Yellow: In a hibernation mode or sleep mode.

Red: The voltage outputs by the power adapter is not right.
The standard power adapter that comes with the box outputs 12V/3A.


Green: The motherboard (PCBA) goes wrong, or in a fault state.

Hi, my led light is flashing in green. I press reset botton and while I am pressing it the green light stops flashing but still in green. Nothing happens. Another try I keep pressing on/off botton and after 10sec pc turns down. I press turn on and the green light keeps flashing. How can I fix that?

Thanks

As stated in the first post & subsequent posts, a green light indicates a fault with the PCBA for which there is not an end user fix.

You'll probably need to return the unit. FAO @Minix - Martin or @MINIX - John , anything further?

Please send an e-mail to support@minix.com.hk, and attach your invoice/receipt.

So I left mine running today for a while and, when I came back to it, the red LED was on. I've tried 2 other power supplies with it (including a known good 6-8A regulated bench PSU) and all I get is the red LED and it won't turn on. :(

@Haitch, the device should work with a power adapter that output 12V/3A.
6-8A is obviously an overload to the device, so the LED light glow RED.

Says someone who obviously knows nothing about electricity 🙄. You cannot overload a device with too much current supply it will only draw what it needs. In actual fact it only uses <1amp most of the time so on your thinking the provided unit would cause a problem. It is over voltage that could cause damage the fact that the one I mentioned is regulated means it cannot do that. Anyone who knows what they’re talking about care to chime in?
PS the provided unit and another two give the same problem so I doubt it is actually the PSU.

Yes, I know very little about electricity:p, what I know is that electricity is decided both by voltage and resistance, that is I=U/R.
In the device, R (or resistance) is fixed, and if the current is detected as 6-8A, I would think the U (voltage) is too large.
The recommended voltage range for Z83-4 is 11V - 13.6V.
If I got anything wrong here, please correct it. :)
