Hi!
After a restart (manual reset button press or windows induced) the system speaker gives a strange buzzing noise after the normal beep. Everything goes fine afterwards. No slowdowns or freezes, errors or anything, just this creepy noise.
I have checked the speaker and restart switch pinsm but they are tightly connected to the right place.
The sound does not occur after a system shutdown and power button start.
Do you have any idea what causes this?
