<p>Thank you Akkana and Ted, my problem with the beeps has ended.
Your suggestions, observations and questions were on point and
indispensable for helping me locate (and comprehend) some exact
instructions for how to resolve the issue.</p>
<p>Here's how it went:<br>

Indeed all indications appeared to point in the bios direction.<br>

Yes, more than once, but nothing useful accessible there.<br>

Hmm. Again, no access via bios, and I suspect not particularly
relevant at the present time as I never seem to hear anything like
"beep codes", only a single beep. But that's an interesting
question that might in the future be useful to have an answer for.
Is there a way to you know of to access status of the bios battery
from a regular terminal command line?<br>

This seems to be an Acer (mis)feature. When I googled<br>
acer netbook loud beep plugging unplugging power<br>
I got lots of hits. It appears that the (mis)feature is called<br>
"Power Control Beep" and many Acers have an option in BIOS to<br>
disable it, so look there first.<br>

As above, been there done that.<br>

If not, try a web search with your actual machine model (you
didn't<br>
tell us the model, you just said "Acer netbook") along with
Linux<br>
and "Power Control Beep", and you might find advice specific
to<br>
that model.<br>

Bingo. I thought the neofetch host line (AO722) that I provided in
my original post was sufficiently clear and obvious, but I suppose I
might better have been more direct or explicit and thorough. The
label on the bottom of the computer says Aspire one 722-BZ480 and
MODEL NO: P1VE6. As it turns out 'Aspire one 722' was the most
productive search string (or the most productive portion thereof) --
just as you suggest it might be.<br>

<p>Alsamixer *does* have a beep channel, just as you suggested it
might in your *first* response to my *first* post. I just
couldn't quite figure out how to find it, didn't correctly
comprehend the manner in which it remained obscure. A case of
"out of sight out of mind". <br>

<p>The rest of the story:</p>
<p>Pertinent results from Google search terms <br>
'linux beep acer aspire one 722-BZ480', the exact links: <br>

<br>
Excerpted from the second link, the clearest and most <br>
effective description I needed to be able to deal with ALSA. <br>
It works exactly as described: <br>
<br>
This is the answer to the million dollar question: disable the AC
adapter / power cord beep in Acer Aspire One AO722 netbook in
Ubuntu 11.10.<br>
... <br>
Then use the utility <br>
# alsamixer <br>
<br>
For portables there are no separate system speakers for the system
beep, therefore the desktop methods won't work. For some
portables, there are two devices, one for the digital HDMI and one
for the analog speaker and headphones. You have to pick the
correct one for the volume settings.<br>
<br>
For the AO722, use F6 to pick the conexant sound card, rather than
the first HDMI sound card.<br>
<br>
Then use the arrow keys to get to the beep column. Type m to
toggle the muting status.</p>
<p>The heart attack beep will be off when the power cord is attached
or removed. But the beep is not altogether muted. The beep
volume seems to be coupled to the master volume or the alert
volume.</p>
<p>Thanks again,</p>
<p>Tom<br>
