Hardware beep sound

[Edanny101]

Hi,

I have a big problem here, While I am using fedora on my Hp mini 110, I can hear a weird beep sound sometimes, I think its hardware problem and try to hard rest my laptop but still same in fedora, tried other OS such as Windows 7 and no beep sound.

Also close all system sound in fedora such as terminal bell but still same.

Fedora 16 gnome (Verne Kernel 3.2.2-1)
Hp mini 110 intel atome 1.66 N570, 2Gb Ram

Thanks in advance.

Did you check in BIOS settings for the reasons which can cause this hardware beep?

Check /var/log/messages for anything odd, particularly on boot or when the beeps occur.

Can you open the box up? It might be useful to know what's physically making the noise.

make sure your Fedora installation isn't loading the "pcspkr" module.

pcspkr is a module that interfaces to the cheap motherboard 'beep' speaker (you are hearing the beep from the motherboard and not from the audio speakers right?). You can completely stop it from loading in any case by blacklisting it:


as the root user, edit the file /etc/modprobe.d/blacklist.conf to add these lines:

blacklist pcspkr
alias pcspkr /bin/true

with that saved, now make sure there's no loaded pcspkr module

modprobe -r pcspkr

The tone speaker on the board should be disabled in Fedora now

The Hp mini 110 BIOS is very simple and limited to change and there is not any thing related to it.

I was open it and go throw a lot of lines, all seams fine to me, and didn't have chance to check it when beep occurred. It will take time to wait for the beep happen, don't know how long but its long time haven heard it.

Dear marko i was read your post at http://fedoraforum.org/forum/showthread.php?t=214607 before and followed your structure but is no effect on stopping the beep sound.

Ok finally I checked the /var/log/messages when the beep occurred and here the messages:
