I have a problem with the Apu3c4. Out of the blue it stoped and started making a beeping sound, very thin that you almost cannot hear it. Now it doesn't work anymore, when plugged in electrically it starts making that beeping sound and no leds are flashing. Do you have experience with this? Should I send it to warranty?
I have attached a small video with the apu making that beeping sound.
Maybe someone of you had this problem or maybe you have some suggestions to make, some tests that I could make to revive the board.
Thank you very much,
