Ubuntu :: No Beep When Battery Gets Discharged?
Mar 26, 2010
When I was using Windows XP, my notebook was beeping very loud when it was running out of power. Since I use Ubuntu it doesnt. I have tried kpowersave but it somehow cannot play ANY SOUNDS. Now I use default power management and it doesn't beep too.
How can I fix it? Its quite important because I often forget to hook it up.

Just installed 9.10 followed by a 10.04 upgrade (wouldn't work as a 10.04 clean install). The install and upgrade all seemed to go well.
But now when booting I get a message saying "checking battery state" and then it boots no further. This is a laptop without a battery installed, running permanently from the mains through the charger.
How can I disable this check so that the laptop will still boot without a battery fitted?

getting back to our laptop, the stability window is ~3.2V. Meaning that when you operate the battery above this the electrolyte is oxidized on the positive electrode and reduced on the negative electrode. Remember that we only want to oxidize and reduce the active materials and don't want to do anything else. All these reactions other than the ones we want are called side reactions and these are really bad for the battery. The nominal voltage of a laptop battery is 3.7 V which means that something bad wants to happen as we use the battery.So long story short, stuff (e.g., passive layers and poor kinetics of reactions) happens and things are not as bad as they seem and you can increase the voltage up to 4.2V without bad things really happening. All chargers for Li-ion cells today cut the battery off when it reaches 4.2V. What you have to realize is that at 4.2V, these side reactions are present in finite amounts and start to chemically kill the battery, but its not that dramatic.
Operating to 4.1V makes things better and extends the life, 4.0 V is even better and so on. So why don't battery manufacturers cut the voltage off at, say, 4 V to get better battery life? Because every time you cut this voltage down you decrease the capacity of the battery and its run time. The 4.2V cutoff is a compromise between good run time and decent (read "not pathetic) life.On the other hand, if you charge the battery and then pull the plug (so to speak), the battery discharges some, the voltage drops, and these reactions become less of a problem and your battery life goes up. So the best things you can do is to charge the laptop (or cell phone, camera etc.) and once its charged, pull the plug. Your battery will thank you for it.As a matter of fact, if you own a Lenovo Thinkpad, you can actually change the state of charge to which you charge the battery using the Battery Maintenance utility. You can change this from charging to 100% state (where the voltage is 4.2V) to 90% so that your voltage is less. You lose some energy is doing that, but atleast you can change it to 100% when you need battery power and put it back down to 90% when you can plug in. I wish my Mac has the same feature.
I typically use the battery for a while (say 1/2 hour to 1 hour), then plug it in and wait to fully charge it, then I pull the plug and use it again for 1/2 hour to 1h and then I repeat this. Takes some getting used to and I forget to do this, but I try.

I have a 3 year old laptop with the original battery and its drained pretty bad. The "Battery may be broken" popup was driving me insane and this is how you disable it, in case you are in the same situation as me. Open terminal
Code:
gconf-editor
Drill down to...
apps --> gnome-power-manager --> notify
uncheck the low_capacity checkbox. This should disable the popup for you if your battery has little life left in it. Now, if any knows how to disable the Avahi popup, let me know.

My beep command stopped working -- it does not beep. I think this happened when I upgraded to Karmic (but could have been earlier). I use the beep command to notify me of important events.
I tried looking in sound settings, and did not find anything suspicious. I also tried googling but most stuff just describes how to "disable the annoying beep". Lastly, I tried different software channels and repositories to find an alternative program to the beep command, but nothing happened.

I use Mythbuntu 9.10 as HTPC and I got where I can turnoff the computer using remote. But how can I get a "beep" to be played during shutdown? by this I would know the computer is shutting off - it is behind a glas door so I don't see if the led's turns off.

I have a HP Laptop with Ubuntu Hardy installed. The system beep makes rapid clicking sound at login window that slowly dissipate and clicking that, so far I can only fix by rebooting, when I play music, reboot after hibernating, and when waking up from suspend. I've turned the system beep off in System/Preferences/Sound but it doesn't do anything.

Every time I shut down my laptop, this loud beeping noise comes out of my computer. It's just one beep, but it's loud and annoying. This has been happening recently, and not from the start of installing Ubuntu to my laptop.

I'm running ubuntu 9.10 on a Dell XPS M1530. Sometimes i get a _VERY_ loud beep-sound, eg when i run out of battery or, the case that has me coming here when i'm working in a virtual terminal (tty1-6) and hit backspace once too often, that is, when the command line is actually empty.Not that big of a deal you might think, but, especially when you're wearing good (read: possibly loud) headphones the experience is that god damn unpleasant that i'd like to make sure it won't happen again.Oh and well, just hitting mute (in gnome, which doesn't have a lot to do with tty1 anyways) won't do the job.

I like the system beep because I can tell checkgmail to beep when an email comes, that way my speakers don't have to be on.Anyways, I did a fresh install of Karmic the other day. Something is being weird with me when I try to re-enable the beep. Karmic blacklisted pcspkr in /etc/modprobe.d/blacklist.conf . Here's what happens:I leave "blacklist pcspkr" in blacklist.conf and restart. I do "sudo modprobe pcspkr" and then "beep", and it beeps. Good.
Then I comment out "blacklist pcspkr" in blacklist.conf and restart. I do "beep". Nothing. I do "sudo modprobe pcspkr" and then "beep". Nothing. I do "lsmod | grep pcspkr". It's listed there as it should be. I check with "sudo grep pcspkr /var/log/dmesg" and find no errors.

It is extremely load and aggravating. My version 9.10. I am have no other issues with the internal speaker besides the low power beep. I have tried: blacklist pcspkr in /etc/modprobe.d/blacklist.conf (actually was already done in 9.10) in gconf-editor gone to apps gnome-power manager, unchecked low power notification
gone to sound preferences muted alert volume. If this was a desktop i would just physically disable the internal speaker, but i don't want to open up my laptop do to possible difficulty of reassembly.

I am using anaconda + ks.cfg to install Linux.
In my case installation does not require any actions from me and there is no need to sit next to PC but it takes some time so I would like to hear some loud sound at the end of the process (e.g. something similar to result of echo -e "a" command) but I cannot find appropriate place in ks.cfg to add thing like this

I've been using my girlfriend's Mackbook Pro and really like the beep sound when pressing backspace at a command prompt and really would like to have it on my ubuntu. However, I've checked "Terminal bell" option in the profile settings, but there is still no beep sound. What am I missing here?

Is there anywhere I can check what is causing this loud system beep or a way to fix this?? I really don't know where to start on this issues. Possibly restart log files but not sure where they're located.

When in a virtual tty, Ubuntu has an extremely annoying audible beep alert to notify the user that he is trying to do something that can't be done. Say for instance, hitting the backspace key at the command prompt. The cursor can not back up from there, so the system issues out a loud obnoxious BEEP in response. I am in a virtual tty often, and have found myself on a quest to eradicate that annoying BEEP from my system, if it is the last thing I do. After trying several modprobe, and other solutions, that did not work, I have found a solution that does.
alsamixer has a setting for 'PC Beep' that can be muted, silencing all audible system complaints from a virtual tty.
It would be a pain to do this every time, so...
amixer is a command line interface to alsamixer. By placing the following command in my .bashrc file, I have solved my problem.
amixer set 'PC Beep' disable

after installing linux mint 7, I have been getting one beep on shutdown, a google search on this came back as a ram problem...but then i ran across a bunch of posts on ubuntu forums about one beep on shutdown, with an older version of ubuntu, grep does return some paramter errors, but in the mint bug report page those are listed as : benign ignore. it doen't bother me in the least, as long as it isn't a warning of impending hardware failure.

I have a habit of watching videos when I go to sleep. So I decided to start using, for example, the following when I laid down:
sudo shutdown -h -P 60
Of course this shuts down the computer in an hour. I was wondering if there was a way I could get the computer to beep a few times for the last 10 Minutes and then a few more times for the last 5 minutes?

This may seem like a stupid question (if not completely ridiculous ), but I was wondering if there's a way to configure audio events so that I can use a wav/ogg sound instead of the PC speaker's default beep for small events like hitting backspace in a text editor when it's the beginning of the document (or any other illegal keyboard action), or in Wine applications when it calls for an "asterisk" sound (it just beeps the PC speaker).
I've looked at similar threads, but they mainly just talk about either the beeps that the machine does when it boots up, or simply turning off the beeping completely. What I want to do is substitute the beeps (that are caused by the OS) for an actual sound that's played through the ALSA/OSS/whatever audio device.

My asus 17" lcd VB171/VB191 monitor has started continuous beeping. Detaching the cable for sound from the computer, the beep stops, but it starts again by plugging the cable in. The motherboard is Tyan S2895 K8WE. The monitor has worked normally for one year.

I have replaced my motherboard, cpu, ram with a retailed 'bundle' of components. When I power up, the cpu fans spins and i can feel my hard drive vibrating but There is no post beep. I could connect one of two four pin pwr2 leads to a motherboard; the first has yellow and black leads, the second, red purple black and yellow. Have you any ideas on my next move?

In order to make alt key works in vim in xterm (I set metaSendEscape in order to make other application works well), I put this in .vimrc:
for i in range(65, 90) + range(97, 122)
exe "set <M-".nr2char(i).">=<Esc>".nr2char(i)
endfor
set ttimeoutlen=50
But the vim will beep (and do some strange thing) after starts. (In urxvt there is no problem). I use binary search to find that it is i = 80 cause the problem. If I just only put "set <M-P>=^[P" in vimrc(^[ is Ctrl-V <ESC>). Xterm also will beep. (Only P will) It is really a weird behavior. The thing which is weirder is if you directly run ":<M-P>=^[P" there is no problem. It only occur when this line is in vimrc.

i'm running Ubuntu 10.04 server and want to turn on the pc-speaker warning-beep.I commented out the line in /etc/modprobe.d blacklist.conf:
#blacklist pcspkr
The beep is now working for root. But somehow it won't work if i log in as a normal user. (i don't know why, but if i install beep the beep-command works for all users...unfortunately beep seems not to make a warning sound in all cases so this is no solution for me)
