Low battery Shutdown, no save!!

I recently Upgraded my mac to Leopard from Tiger and since then my computer no longer when on low battery saves my work and then shuts down. In tiger at around 15% battery life my mac would warn me of my low battery then at around 10% tell me its saving all of my work then going to shut down. So then when i plug my mac into an outlet it opens all the same applications and work i had before. This is all gone in leopard, at around 10% it just shuts down, no warning or save. Am i missing something here, can u explain to me whats going on?

We had similar issues on both of our PowerBooks (both aluminum G4's) after Leopard was installed. However, the problem eventually went away (after about a week or two of use). I believe that Leopard had to re-learn the state of the battery, and so it's initial guesses at how much battery life was left were way off, catching it by surprise when the battery suddenly expired. In our case, Leopard now seems to have a much better sense of the battery capacity, so perhaps you will see improvement with time.

T500 performance 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.

Low battery shutdown

Just bought a refurbished iBook - white duel usb. It shuts down whenever the battery level drops to about 30%. That seems premature. Is there a way to change it to.. say.. 10%? I've tried all sorts of buttons in the preference menu, but I can't seem to find the right option.
Thanks.

I have always considered the cost of a replacement
battery part of the cost of convenience of
portability. Take the price of a new battery and
divide it by 24 to determine the monthly cost. Is it
worth it to you?
As far as the question about a battery warning in
"Classic Mode," do you mean when booted in OS 9?
"Classic" is the emulation of OS 9 when booted in OS
X, so I'm not sure whether you are asking if you will
get the warning when running a Classic application
within OS X or when booted in OS 9.
When booted in OS 9, there is a battery meter on the
Control Strip that gives you a constant readout of
battery time remaining. It's been so long since I
worked off the battery when booted in OS 9 that I
don't remember for certain whether there is a low
battery warning in addition to the readout.
When working within an application in Classic while
booted in OS X, the OS X software should override the
Classic application and give you the warning.
Thanks Ronda
Yes, I did mean working within an application in Classic while booted in OS X. Today I did another experiment - when my iBook went into sleep mode (without warning) at an indicated 30% charge, I connected the power adaptor for about 10 minutes, then woke the computer up with 20% indicated. Then I disconnected the power adapter and kept working. Sure enough I got a low power warning, but kept right on working until the computer went into forced sleep. Then reconnected the power adapter until fully charged. The time remaining in the battery menu seems now to be much closer to what it was when the battery was new.
Ronda, I can't help feeling that there are some subtleties in the Calibration process that Apple is not telling us about !!
What du you think?

Low battery shutdown / sleep

Is there an option in Leopard or Tiger to force the laptop to go into sleep or shutdown if the battery level goes below a certain level?

Well what's weird with my MBP, is that when it goes into forced-sleep, after the battery runs out (like my old PB G4 did) it essentially shuts down. It doesn't respond to anything after I plugin. The only thing I can do to wake it up is to hit the power button, and it starts up as if I shut down.
This wouldn't be so bad if I wasn't working on open apps at the time.
Does the new MBPs have a Power Management Reset switch like older PBs?

After low battery shutdown settings not stable

I was under the assumption that running the battery down once a year was good. I let the MB Pro run down to 11% expecting to get a warning of some sort when it got to 10%. Instead the machine just shut down (and not in a nice way-it just went black). When I powered it up and turned it back on the first thing noticed was the clock. It was set to December 31, 2000. Next, I noticed that the machine was not connecting to the local network but was recognizing two networks that are supposed to be invisible. When I logged into one of the networks I got two or three messages asking if it were all right for certain config files to accept incoming connections. I accepted not knowing what they were nor where. I got the clock back to date by opening the Date & Time Preferences (they automatically corrected themselves).
Here is the problem. The computer is not remembering the network like it did previous to this mess. If I restart it does not automatically join its preferred network. It sees it but asks for a password. Before it joined when I got to the office.
Next, Dashboard seems to be dead. None of the widgets connect/update and I cannot remove the blank open ones from the screen.
I have run Disk Utility to verify the disk and repair permissions but no change is seen. I have restarted a couple times but nothing changes. Your help is appreciated.

Hi Donald,
Did you try a SMU reset?

Macbook Pro won't login after sleep (sleep with low battery -- mac turned off maybe it's called save sleep)

Macbook Pro won't login after sleep (sleep with low battery --> mac turned off maybe it's called save sleep)
So if I hit the powerbutton my mbp booted like it is booting from the save sleep (so very fast and the login screen is there in about 10 sec.and there is no apple logo while booting just the desktop screen in "unsharp" ore foggy however...)
Then when i see the login (if the keyboard backlight turned on) i wand do tipe in my code but it won't work... the trackpad is not working; and when i plug-in a usb mouse the mbp is not powering on the usb-mouse (laser is off)
Why is that this way?
Is there n option to wake up the mbp fromm deep/save sleep without haveing issiues after that?

Sorry for such a long delayed response...
I was able to get to an apple store this past weekend, and let me tell you... I'm about finished with there great "support".
Right before I went to the store, I tried to eject a disk. Well the cloth in the SuperDrive (I assume to protect the drive from dust and such) Pulled up with my disk. So I get the Apple store, describe my problem and what happened with the cloth piece. The "Genius" writes up a form and tells me they have to run diagnostic and it will take a couple days... and I will get a call when its done (1-3 days).
Well on day number 3 I called up the store and they told me it was ready to be picked up? I asked if anything had been fixed and they told me they could not reproduce my "sleep issue", so they couldn't fix that.. but told me the cloth piece in the SuperDrive had been fixed.
I drive an hour (one way) to the Apple store to find that all they did was PULLED OUT the cloth... they did not replace it! So basically I have a hole for a Super Drive.
I asked why I was not called to say that my computer was ready to be picked up... didn't get an answer on that one.
I asked why my SuperDrive was said to be fixed, when nothing was done... they told me that it would have to be sent out to the factory store for that to be fixed (FIRST TIME THEY MENTIONED THAT!) Oh, and that would take 5-7 business days. Well that's not going to happen right now considering I'm a college student that NEEDS a working computer!
So I go home, angry... start just putting all my important documents back on the computer. And the screen starts blinking!!!! I guess now I have the same thing described in another post on these forms...
Lets just say that I'm not very happy with Apple right now! If anybody else has success on either the sleep issue or the screen blinking issue, please let me know!
Thank you!

Bogus Low Battery light? Results in Shutdown.

I charged my PB to 100% and put it on sleep mode. I dragged my finger on it and woke it up to find it reading low battery..it was only sitting for 15min! I ignored it and opened a few apps and poof...the low battery icon went away and the battery read 75% power. It has done this a few times. Just last night I had it on stand by with 100% charge. Low batt lite came on, i again ignored it as before. This time it just shut off and re started itself. Another time it just shut off with no warning. I have done the security sweep and hardboot with no luck. It's only a couple of moths old and hardly used. I have tried selling this before it happened and people laughed at me for buying crappy RIM products. I love my Curve phone but this thing really does suck. Any thoughts on how to fix this?

if you wiped it and still present, maybe you have a defective unit. non of my 3 playbooks does this.
it does have a 1 yea warranty from RIM.

Is there any way to turn the low battery warnings off for my Mighty Mouse?

I noticed a pop-up warning on start-up when my battery life reached two bars for my new wireless Mighty Mouse. Also the battery sign kept on flashing in my menu bar.
I was wondering if there was a way of turning these warnings off, save uninstalling the Apple software, or should I just change batteries and not worry about getting as much use as I can out of my current pair.
I've also turned off "show bluetooth status in menu bar" in mouse preferences but it keeps on turning on at startup and it doesn't seem to get rid of the low battery indicator flashing on and off in the menu anyway.
(And would turning off system events as a login item disable the startup warning?).
Thanks
Paul

Hello Paul:
My own experience is that when the warning pops up (regardless of the yellow bars), you need to change the batteries. In my case I use rechargeable 2500 mAh batteries and an Energizer recharger that charges AA and AAA batteries in 15 minutes.

Low battery warning percent fixed??

I have Vaio VPCYB15AG with Win 7 Ultimate SP1 32Bit retail. In it's advanced power options even though I can set percentage value for Low battery warning, I find that the warning is given (Blinking green power LED) when battery falls to 12%.Is this level kind of hard wired into the product or will it be a software / hardware bug?Thanks

Hi mmp_2013,
Thank you for considering Sony Community!
If the LED or the light indicator is blinking, then something is going on with the battery. It could be hardware but we cannot tell right away. Please follow the steps here to isolate your issue:
Check the battery health on Vaio Care (Desktop) - If indicated as "critical" then it already hardware issue
Power cycle - Remove the battery and all peripherals -> press and hold the power button for 5 seconds OR, if the battery is not removable, remove all peripherals-> look for a battery off button on the bottom of the laptop -> push the button for 5 seconds -> you may use a safety pin if you see a pinhole.
Reset BIOS - Turn off the unit -> press and power button and immediately, keep hitting F2 key. Once in BIOS, go to Exit tab -> Get Default Values -> hit Enter -> Save changes and exit.
Download or update Sony® Shared Library, Sony® Firmware Extension Parser Device Driver, BIOS Update Utility from Sony's website based on your location or from where you purchase the laptop.
Your Vaio VPCYB15AG is an Asia-Pacific model and we have limited information about your unit.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Hope these help.

Kernel Panic at low battery with MacBook bug found - with solution

Hello All,
I think I've found a bug with Leopard concerning laptops. I started a thread which I'll link to below.
http://discussions.apple.com/thread.jspa?threadID=1219413
Other people have had this same issue - I've seen it on a few different posts. Does anyone know the best way to contact Apple regarding this? I don't know how active they are in reading this forum, and I want to make sure they know about this, as it's probably something that can be fixed with an OS update.
To summarize, I'm including a couple of key posts:
Posted Nov 4th 2007...
Hello,
I just got one of the new November 07 MacBooks. The machine is great, and screams with the pre-installed Leopard.
First thing I did was plug it in to charge as I started configuring software. Once it was fully charged, I pulled the plug, and began using it on battery. My plan was to calibrate the battery, by running it all the way until it forced a sleep, then shutting down and plugging it in again, as Apple recommends.
Problem is, I never got the "Low Battery" warning, or even the sleep warning. At around 10 minutes of power left, I simply got a kernel panic. A few seconds later, the laptop just switched off.
I plugged in again for a few minutes, then ran it down again to see if I could reproduce the error, and I did get the low battery warning.
The next time the battery ran down, it gave me the kernel panic.
Is this happening to anyone else? Is it a new MacBook problem, or a leopard power management problem? I'm having no other issues at all with the MacBook or Leopard. Any help would be appreciated.
Thanks!
Nov 12th, 2007...
Well, It's been a few cycles since the first one, and all is well. I'm getting the low battery warning when it runs low, and no kernel panics (knocking on all available wood). If I start having problems in the future, I'll update this thread, but for now I'm marking it answered. It was probably Leopard not reading the uncalibrated battery correctly.
Dec, 31st 2007.....
Hello all,
Short followup here: I've have 30 successful cycles after the first couple of kernel panics, and it's time to calibrate the battery again. I tried to do it yesterday - charged the battery all the way, used the macbook while plugged in for two hours, unplugged the adapter and continued to use it until I got the low battery warning. I shut down everything and let it sit - waiting for it to go to sleep. Instead, I got a kernel panic, and the computer shut down. It would not restart until I plugged it in, but I know there was some battery left, since it panicked at 2% battery. I let it charge for an hour or so, then used it again until I got the low battery warning. This time, it went down to 0%, but panicked and shut down instead of going to sleep.
I'm trying this again, after charging all the way last night, and just leaving it on to drain. I'm at 20% right now, and I'll post to let you know what happened.
Dec 31st, 2007....
Hello All - I think I've figured this out. Looks like a software bug with Leopard.
I did get another kernel panic just now at 0%, after the low battery warning. But then I had a revelation. In trying to calibrate the battery, I had set my energy saver settings to never sleep under the battery settings - so I could leave the notebook overnight to drain. I gave it a bit of a charge, then set the battery setting (in energy saver) to sleep after 20 minutes. I restarted, used the computer for a while, got the low battery warning, the computer went down to 0%, then went to sleep as it should.
I believe that since I had the computer set to "never" go to sleep, Leopard didn't know how to handle it when the battery ran down, and kernel panicked. Perhaps this happens on new MacBooks, because these settings aren't written yet? Regardless, it's obviously an OS level bug here.
For those having the problem, make sure your battery settings under energy saver are set to allow sleep after a time.

Hope this helps everyone out.

Same problem with shortened battery life here with 10.6.2 (2009 unibody 15" MBP 2.53 GHz.) Shutting down and removing the battery seems to have brought fully charged battery life back from less than 2 hours to over 5 again. Didn't bother holding down the power button with the battery out though.
A few notes:
1. Prior to the shut down + battery removal, I had noticed unusual warmth despite the CPU being only lightly loaded. Activity monitor showed no app using more than 4% of the CPU, with just a few apps running (Safari, Mail, iCal, Finder).
2. Months ago, just a PRAM reset seemed to fix the problem, possibly with 10.6.1 or 10.6. Can't remember for sure. But PRAM reset doesn't help any more with 10.6.2.
3. I have never reset the SMC.
4. I don't recall this problem happening with any of the 10.5 releases. Just with 10.6.x.
5. The bottom of the MBP's enclosure is cool again after the shutdown + battery removal.
6. I am also running 10.6.2 on a 2008 aluminum iMac (20" 2.4 GHz) and haven't noticed any unusual temperatures, but it's much harder to tell. And of course, there's no battery life to measure.
I'll see if the problem returns again, but it really seems like a Mac OS X problem instead of a firmware or runaway app problem. Maybe some daemon is stuck in a busywait loop or something?

MacBook shuts down after low battery warning

Hi,
up until recently my macbook's battery has been working just fine. but then lately i noticed that a few minutes after it displays the low battery warning it shuts down by itself.
before, when the low battery warning would display i could still continue working on my macbook for several minutes until it goes to sleep -- only then would i connect it to the power cord.
unlike the other posts (concerning batteries) that i've read, i have no problems turning my macbook on/off before or after this event has occured. neither does it shut itself down when the battery is halfway. my problem really only happens after the low battery warning has been displayed.
i wanted to calibrate my battery but then that would require my macbook to go to sleep once it reaches a battery level of less than 5%-10% -- mine just shuts down completely.
is this shutting down thing a substitution mechanism to save the laptop's memory -- instead of going to sleep, it'd just shut down?? how can i fix this?
thanks in advance for the help.
MacBook Mac OS X (10.4.8) 512MB, 2GHz Intel Core Duo

For what it is worth, I now have the same issue. Only I don't even see the low battery warning, it gets to 15% or 10% and bang, no power. This is not good, by the way and is bound to corrupt something in the system as OSX requires some house keeping when you shut down the computer properly. This instant off is not a proper shut down. I took my MacBook in and they wouldnt simply replace the battery, they want to keep the computer and give it back to me in a few days. I rely on this puter for work 5 days a week, so I was trying to avoid this.
Oh well I guess a trip to the Apple store is unavoidable.

Low battery life on new 4th generation nano?

I got a 16 gb 4th gen nano yesterday. When I first turned it on, I was pleased to see that the battery was almost completely full. I took it to work, and listened to it for about an hour total, coupled with playing games on it, the charge level had drop to near half, not once, but twice (I'd brought a charger with me - the Apple charger that was recalled yesterday, ironically).
Today, it was fully charged thanks to the new 4th-gen compatible new car charger I bought when returning the recalled adapter for a refund. With the slightly over an hour of playing music and playing games for not even an hour total; the battery is now out - I've got the low battery message on screen. Do new batteries need a few charge cycles before they hit max capacity or something? Tomorrow I may recharge it and just let it play on shuffle while I leave it alone and see how long it lasts, but it still seems like it lasted pretty short.
Any thoughts?

I am having a similar problem with my nano 4g battery. I just bought this on Monday. Got it home, set the language, time zone and time then plugged it into my computer to synch it. When I got it out of the box it was 3/4 charged. Before the synch was even done the nano showed it was fully charged. After synching I unplugged it from the computer and clicked a few buttons on the nano and immediately a little sliver of the battery display had gone down! I hadn't even played 1 song yet.
I plugged it back into my computer and the nano still showed it fully charged. yet when I unplugged it, it still showed it as a little bit of the battery having been used. I played 1 or 2 songs and the battery went display went down a little more.
That night I plugged the nano into the wall with my adapter (we've had this one a while so it can't be one of the new ones that was recalled and we've charged other iPods with it) and let it sit overnight. The next morning I unplugged the nano clicked around on it a few times and again the battery display went down a sliver. I thought maybe it was a display issue, figured I'd take it to work and give it a try. After about 1-1/2 hours of listening (occasionally pausing it), the battery display was down to about 1/2.
I charged it again on the computer. This time it took between 1-2 hours on the computer for it to show fully charged. Brought it to work again today and the same darn thing is happening with the battery display. I have not tried running it overnight or for several hours to see if it drains completely.
I have it set to Energy Saver.
Are lots having these battery issues? Not sure if I should take it back to Best Buy and exchange it for another one just yet.
Brian, if you read this, did your restoring end up really helping? Seems like you shouldn't have to do that and re-install software that was already on the nano when you purchased it, but if that completely fixed your battery problem, I'll give it a try.
Any suggestions would be appreciated. Thanks!

[Solved] Warn on low battery/halt

Hi,
This is my third day of arch, and on two occasions so-far I have forgotten that my laptop is unplugged and so has run out of battery and turned off. I thought that maybe it was time to do something about it.
How do I go about calling a script (i.e. to halt or to play a sound or something) when the battery is low. (1)Would /etc/acpi/handler.sh be the right place to put things in? (have got the laptop dimming when ac power is removed, and the screen turning off when lip is closed)
From perusing the forums it seems someone mentioned laptop tools, however from reading documentation on it, in various places, it scares me a little. Things about killing HDs. (2) Can I be sure that I have disabled any RAM-killing features? Also, from looking in /etc/laptop-mode/laptop-mode.conf it seems that it only supports hibernate on low battery, however this is another thing I have yet to set-up. (3)Can hibernating be done with a swapfile smaller than my ram (RAM is 1.5gb, swap 1gb)? If no, (6) can I change my swapfile size w/o losing data on my /home partition (the partition preceding the swapfile)?
Thanks if you managed to get through the jumble above. I fail epicly at forum posts. Never can seem to make them totally comprehensible.
Edit: If relevant: Laptop is HP 530, running on Openbox.

# Syslog configuration control
# Syslog daemons have a tendency to sync their log files when entries are
# written to them. This causes disks to spin up, which is not very nice when
# you're trying to save power. The syslog.conf can be tweaked to *not* sync
# a given file, by prepending the log file name with a dash, like this:
# mail.* -/var/log/mail/mail.log
# Using the following options, you can let laptop mode switch between
# different syslog configurations depending on whether you are working on
# battery or on AC power. To set this up, start by configuring these options
# for your syslog daemon, and then run lm-syslog-setup to create the various
# files. Then edit the laptop mode-specific syslog configuration files to
# remove the syncs only when laptop mode is active.
# Should laptop mode tools control which syslog.conf should be used?

# LCD brightness settings
# Using these settings, you can make laptop mode tools automatically adjust
# your LCD's brightness settings. The settings are extremely simple -- they
# only allow for the execution of a command, nothing more. The reason for this
# is that LCD brightness settings are very different between laptop vendors.
# Suggestions for commands:
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
# cat /proc/acpi/video/VID/LCD/brightness
# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.
# * For Toshiba laptops, use the command "toshset" with the -lcd or -inten
# command. Read the toshset(1) manual page for more information on the
# parameters for this command. If you use this command, set
# BRIGHTNESS_OUTPUT to "/dev/null".

Apple icon, sad face, and low battery symbol (not charging) what's going on

my iPod U2 4th gen started acting up on me. it needed to be reset more and more often, until it decided to just stop working all together. it would show me the apple sign, sad face, and low battery symbols. bought and installed new battery, won't charge. it changes from apple icon to sad face back and forth on it's on when plugged into wall with firewire. goes from apple icon to sad face when connected to pc via USB. pc won't recognize it. please help! i've tried everything! is there something wrong with my hard drive? i'll pay anything to save the files on my hard drive. HELP!!!!!

Hey man...I have the EXACT same Ipod with the EXACT same problem. I went to the apple store and they told me I had to wait 3 days to make an appointment with a "Mac Genius" to look at it and that with all the repairs done it would probably cost me $150. Frustrated, I went home and did some research and heres what I found:

I kid you not. So basically I put the wall charger on, let it charge for 3 hours. Took it off the wall plug and then slapped the $#!t out of it 4 or five times. Then turned it on. Same sad face. Tried a combination of the reboot procedure and slapping around and now it works! Good luck and hope it works for you too!
I feel like going to the apple store and slapping the crap out of "Mac Rip Ppl off Genius"

Low battery Shutdown, no save!!
