I plug in the board,but the power led flashed and the fan just span for a second,and then shut down.It doesn’t work now.What’s wrong with it?
Can you please provide more details? Does It happen after press power button? What’s the last action before this happen?
If you have a USB keyboard plugged in, do any of the indicator lights work? E.G., caps lock or num lock.
thank you for the answers！
I learned it later that it should be the problem of using wrong power supply.Since the power interface also fits my laptop
power supply , which have a 20v–4.5A output. I might have accidentally mixed them up.
