Until a couple of weeks ago there wasn't any problem.
But now I hear 5 beeps when I switch on my mini-PC.
I use a mini-case with external adapter of 19V, 4,7A (european notation).
Switching to a 16V adapter, I hear no beeps.
Measuring the output voltage of my previous adapter, it is still 19V.
And with these 19V adapter, after the startup, the mini-PC functions normal!
In the manual I cannot find anything about beep warnings.
So let me know what the meaning is of these 5 beeps.

Thanks in advance for helping a 70+ guy from Holland.]]> Tue, 01 Dec 2020 19:11:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=17380&PID=81851&title=j3455bitx-5-beeps-by-startup#81851
