Low battery alarm?

I was reading around about ho to calibrate the Mac book Pro's battery so i followed what Apple said, so i was raining the battery till it was like 4% and i didn't get the alarm, i was wondering if maybe it was turned off. If i could turn it on how do i do it? or if there isnt a low battery alarm? Which one is it????

However, let your computer run until the computer puts itself to sleep. Then plug it in and charge full as per instructions.

  • No low battery alarm when on the call. (Nokia 700)

    There must be some bug with the low battery alarm on Nokia 700. When the phone is on a long call, it just shuts down without any alarm at all. I had this issue several times. My battery shows that it’s full for about 30% or something. Then I call and have a long conversation. And the phone just dies without any alarm at all. When I try to start it again it seems that battery is drained and I have to charge it to turn it on again.
    When the phone is in standby and battery is starting to running low, it beeps and shows a message. However, when I am on the call, nothings is happening, it doesn’t give me a message that battery is low and that it’s time to connect to the charger.
    It’s a most important functionality I expect from the mobile phone, to be able to make a call reliably.
    It’s a Nokia 700
    Software version: 111.030.0609
    Software version date: 2011-11-26

    Product code: 059G2D6
    Type: RM-670

    It seems to me that after I've got version 111.030.0609 installed by Nokia service technician, my Nokia 700 never goes into power saving mode (and it doesn't matter what do I have in Setup / power saving / power saving query). It doesn't turn saving on and it doesn't ask me about it. Something must be wrong with 111.030.0609

  • Nokia X6 - Low battery alarm / indicator ...

    Hi guys,
    My phone was very silent today and when I tried to use it, I found that the battery has gone ... but I do not remember an alarm or any indication that battery was low last night.
    How do I turn on the low battery alarm ? 
    I have disabled the following in an attempt to get rid of that annoying nokia start up tone. Does this disable the low battery alarm as well ?
    Settings->personal->profile->general->personalise->warning tones = OFF
    Thanks.
    Solved!

    hi everybody,
    Some times I feel that people buy a new phone, and then just after try to personalise it wothout going through the USER GUIDE.
    Why I get this feeling is, if u all go through the questions asked by the beginners looks to me are very basic.
    please do not think that every phone model has the same type of settings (may be in the same brand upto some extent)
    hence my appeal is first go through the manual one by one keeping u r phone on and check the menu one by one , this will take maximum Two hours if u do it contineously.
    So please do this run for the at least once, so that u will realise the value of it and see the difference.
    then u can minimise critisising the manufacturer unless u have a very specific problem in u r phone.

  • X6 Audible low battery warning

    Hi, is there an audible low battery alarm ? I've seen only the visual indicators but not any audio warning. If it exists can I change the sound file associated to it? Can I change the volume of the alarm?
    Regards.

    T-reminder is one of the BEST... It reminds you for other things like Missed events and Battery fully charged too..

  • Low battery audible notification

    I've had my BB8200 pearl flip for about 6 months now.  Occasionally I forget to charge my battery and will have the phone in my pocket and it will die and turn off.  I might go hours before noticing it has turned off and often I have missed an important call.  With previous phones I have had they would always have an intermittent beep or audible warning me the battery was low, I would then charge it up if I could or I would turn functions off to extend battery life until I could get it recharged. 
    It surprises me that there is no option for this kind of feature for this phone, is this the case for all blackberry phones or just this model?
    Is there any chance that it was just an overlooked feature and might be added in a future release of OS update?
    This forum has been great so for in helping me answer questions with out even having to post, I just read through previous posts and can usally find my answer that way.  So far I have only seen one other post regarding the low battery notification... it had 0 replies.
    Thanks for any and all help offered.

    You know what, I think I have heard the beep in my earpiece... I can't honestly say I have heard it beep audibly from the speaker.
    You could check out MeterBerry, which will give you a low battery alarm.

  • Critical Battery alarm needs to be heard, even when muted.

    Hello all and thanks for the support.
    I have a DV7 w/Vista Home Premium SP2 64-bit that is used for telecommuting. The Citrix app I remotely log into fills the entire screen including the task bar of the local machine with the desktop of the remote machine. I never see the warnings of low/critical battery. I have changed the sound in Windows sound control to a more obnoxius sound (ringout.wav) so I hear it during normal hours.
    My problem is that most (just about all) of the time the laptop is muted so that my young child is not waken during nap time or late at night when I can actually work. I need the critical battery alarm to umute the sound and possibly turn it up/down to a reasonable volume to let me know that I need to plug it in. Is there a way to do this? Or even put a message on the screen like the volume control stating to plug in NOW.

  • [SOLVED] Low battery warning form acpi

    Hello!
    I hope you could help me out, as I am stuck.
    I am trying to automate pm-utils stuff on my laptop, that I have until now been doing by hand with CLI. I installed acpid and I really like how it works as it is very easy and clean to add event handling for closing laptop lid etc.
    But I was unable to use /etc/acpi/handler.sh to detect low battery warning. Only event that is received under "battery" is when the AC adapter is plugged in or battery is removed/inserted, but not when battery is low. 
    I tried to find more info on this, but discovered only that it is supposedly possible to configure alarm level in /proc/acpi/battery/BAT1/alarm, but that file seams to be depreciated and it's replacement (?) /sys/class/power_supply/BAT1/alarm contains a number resulting in about 3% charge, that should have been sufficient for at least writing to log file if any event was received from the battery, but nothing was. (And anyway, I don't know how to configure it using this file, as I am not allowed to write to it and it gets overwriten by something.)
    So I could really use some pointers on why the acpi event for low battery doesn't get generated (or why I am missing it) or what alternatives I have.
    I really would not like to run a cron job for checking battery level, as the acpi event method seams much more beautiful to me and would allow me to sleep better.
    Thanks a lot!

    /dev/zero wrote:No worries :-) If you can think of any ways to improve the script, I'd be interested to know. It isn't perfect because output from "acpi -b" is unpredictable.
    I did adapt your script a bit to suite my needs (Thanks for showing how to write deamon scripts! I haven't thought that it is so straightforward and beauty full.) , but I wouldn't say I improved it as I am basically illiterate in bash.
    For now I deal with the output of "acbi -b" by searching for the "NN%" (with grep, as I know not of a better way) - remaining percent of battery charge - in it, as I suspect this sub string  would allays appear in "acbi -b" output even when the 'remaining time' part is unpredictable (haven't checked it though!).
    Also, my laptop is usually on mute so I changed the text-to-speech warning to a i3-nagbar popping up. (And along the way learned how to control spawned processes in bash! I love just GNU/Linux!).
    /usr/sbin/battery_monitor_loop
    #! /bin/bash
    SLEEP_TIME=5 # Default time between checks.
    SAFE_PERCENT=30 # Still safe at this level.
    DANGER_PERCENT=15 # Warn when battery at this level.
    CRITICAL_PERCENT=5 # Hibernate when battery at this level.
    NAGBAR_PID=0
    export DISPLAY=:0.0
    function launchNagBar
    i3-nagbar -m 'Battery low!' -b 'Hibernate!' 'pm-hibernate' >/dev/null 2>&1 &
    NAGBAR_PID=$!
    function killNagBar
    if [[ $NAGBAR_PID -ne 0 ]]; then
    ps -p $NAGBAR_PID | grep "i3-nagbar"
    if [[ $? -eq 0 ]]; then
    kill $NAGBAR_PID
    fi
    NAGBAR_PID=0
    fi
    while [ true ]; do
    killNagBar
    if [[ -n $(acpi -b | grep -i discharging) ]]; then
    rem_bat=$(acpi -b | grep -Eo "[0-9]+%" | grep -Eo "[0-9]+")
    if [[ $rem_bat -gt $SAFE_PERCENT ]]; then
    SLEEP_TIME=10
    else
    SLEEP_TIME=5
    if [[ $rem_bat -le $DANGER_PERCENT ]]; then
    SLEEP_TIME=2
    launchNagBar
    fi
    if [[ $rem_bat -le $CRITICAL_PERCENT ]]; then
    SLEEP_TIME=1
    pm-hibernate
    fi
    fi
    else
    SLEEP_TIME=10
    fi
    sleep ${SLEEP_TIME}m
    done
    Hm, and just now I got an idea, that, in order to avoid the unpredictable "acpi -b" I could use the acpi information form /sys/class/power_supply/BAT1/* directly as I already have a deamon running. Will try that out.

  • LOW BATTERY ALERT!!!

    HEY! I OWN A SATELLITE A305-S6858 AND WHEN THE BATTERY  GETS TO A LOW POINT I ONLY GET A QUICK ON SCREEN MESSAGE "10% BATTERY POWER REMAINING". I CAN NOT FIND AN AUDIO ALERT LOUD ENOUGH TO WARN ME RIGHT BEFORE IT SHUTS DOWN. I HAVE GONE TO CONTROL PANEL AND CHOSEN THE LOUDEST ALERT I COULD FIND BUT IT  IS BARELY LOUD ENOUGH TO TAKE NOTICE. I AM USE TO A MUCH LOUDER AND REPETITIVE WARNING SYSTEM ON MY LAST LAPTOP (ALSO A SATELLITE).
    ANY SUGGESTIONS/ADVICE ARE VERY MUCH APPRECIATED.

    According to Microsoft this is by design.. check this out  "Low" and "Critical" battery alarms do not sound on a Windows Vista based computer
    HOpe this helps. Thanks!
    peace on earth \m/

  • Bluetooth Low Battery Notification

    My bluetooth mighty mouse kept on losing it's connection - I then looked to see that only 5% was remaining in the battery. Now, before Snow Leopard I received warnings that the battery was low so I could then charge it up. Is this happening to anyone else where they are not receiving low battery notices?

    Yes, I miss this feature too. Why did Apple take it out. I appreciate the power percentage display more than the arbitrary Green, Yellow, Red bars, but now I don't get a warning when my batteries are running low. On top of this, the battery level readings seem really inaccurate. I placed freshly recharged batteries in to my BT Mighty Mouse and the reading only indicated "73%". 5 minutes later, I checked again and it ready "66%" which was alarming. So I checked about 30 minutes later and it read "68%". Does anyone know what's going on with this? It's bad enough the low battery warning is gone, but now it seems Leopard is pretty poor at determining those battery levels.

  • T500 performanc​e loss and restart issue after low battery shutdown

    Hi,
    Some days ago I experienced a significant loss in performance of my T500. Unfortunately it seems to be a continuous loss and the games I play, e.g. empire total war that did run ok before are nearly unplayable at the moment.
    Additionally, when the computer shuts down due to low battery, it no longer manages to resume windows but always crashs during reboot (black screen and hard disk symbol is moving, no other activity for 10 minutes)
    I am working with the standard vista installation and installed all automatic updates, but also every time when I shutdown the computer, no matter how long it has been running (even after 1 minute and after a rebooting 3 minutes ago), the red shutdown symbol in start shows that an update needs to be installed.
    any ideas?
    Many thanks in advance !

    Well, the problem, seem's to have reoccured: Battery ran out (even the indicator leds on the side didn't show any life), Time reset  to 1.1.2001, again some rebooting and setting the time again...
    Is this a sign of a degrading battery health status?
    It looks like reseting the SMC didn't help after all.

  • Ios 7.1 = no Wifi on iPhone 4s   very low battery runtime... HELP!!!

    ios 7.1 = no Wifi on iPhone 4s + very low battery runtime... HELP!!!

    Welcome, sorry to hear your news, there are numerous threads on this issue. Try the trouble shooting on the other threads, I do not recommend sticking it in the freezer or heating with a hair dryer though,
    If it's within warranty and trouble shooting doesn't work, get it. Ack to apple ASAP and get it replaced.
    Many others are in the same position, who also have a 4s
    Good luck

  • I have a iPhone 4 and lately it has been shutting down randomly when I still have battery left. It also doesn't turn back on, until I plug it in to the charger. But when I plug it in, the low battery sign shows up then comes to the lock screen with 68%.
