Macbook no longer "sleeps" after 'low battery' warning, just suddenly dies

My macbook (just over a year old) used to give me a warning with 10 minutes left that it would sleep so as my data was not lost, if I didn't plug it in. However, recently, it has stopped doing this - instead of sleeping, if I don't get to a power source in time within 10 minutes, it simply cuts out, with the sound of the hard drive stopping - like if you shut down a frozen macbook with the power button.
This is REALLY irritating - what's going on? Why does it not sleep anymore, and is there any way to fix it?
I'm on Tiger 10.4.11, with an intel macbook...

Same Problem here. Tried several calibrations, smc and pram zap (well i guess there is no pram any longer so it zaps something else). Now I found another post where they talk about the battry 1.2 update. http://discussions.apple.com/thread.jspa?threadID=1449128&tstart=60
I remember when trying to do an battery update to 1.3 manually the update told me that it is not for my macbook. But - I found the 1.3 update Bundle in /System/Library/Configuration/BatteryUpdater.bundle
1. I Removed /System/Library/Configuration/BatteryUpdater.bundle from my system
2. rebooted
3. Emptied trash
4. Installed update 1.2 by Softwarupdate.
I will now do an SMC reset an then let the battery run low and watch what happens.
Then do a calibration.
I have the problem here in different ways. Sometimes Macbook shuts down suddenly after low battery warning, sometimes it sleep, almost never it hibernates.
My Battery was replace after showing the x symptome about a year ago but now it looks bad again

2009 MacBook Pro shuts off after low battery warning.

Today I got the warning at 10% and about a minute later, the computer just zapped off. I only had internet (Facebook and email) and iTunes open. This has happened before, more often recently, where it shuts off shortly after the warning. I've been wondering if I have a bad battery because sometimes the computer has drained all the way to 0% and then zaps off.
Is this fixable with the current battery? Or is it just old and likely needs replacement?
Any input is appreciated. Thanks!!

Apple actually has a section of their website dedicated to explaining how recharge-able batteries work these days. It includes some tips on how to maximize your battery life.

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.

Sleep without low battery warning

Hey all,
My MBP 17" - 3weeks old- has twice in the past 48 hours gone to sleep straight without any low battery warning. It has made numerous beeps while just going to sleep but wakes normally.
Suggestions?

If you haven't already, make sure to calibrate the battery, following the exact instructions in the manual or on Apple's article on calibrating the battery. (Make sure to scroll to the bottom for the MacBook Pro instructions.)

Shut down after low battery warning

Hi
After I get the low battery warning on my iBook G4 (about 30 seconds) my iBook unexpectedly shuts down, I have tried recalibrating the battery several times, including shutting the lid to put it to sleep after the warning then plugging it in and waking it (to recalibrate you are supposed to wait until the machine sleeps) and letting it charge right up.
I have also tried resetting the PMU, although I dont think this is working as I hit shift-ctrl-apple/option-and the power button, and all that happens is the machine starts up as usual, according to the documentation, I should have to then power up the machine.
Is itr just that my battery hasd had it? I have notice it only takes an hour/hour and a half to run the battery down, and only about 30mins or so to charge.
Thanks for any help in advance.
Mike

That definitely sounds like a battery that wants to be replaced.
My iBook behaved in a similar manner--except the "low battery" warning wouldn't even show up!
I think it's time for you to pick up a new battery--they run about $100.

M70 freezes when connecting AC Adapter after low battery warning

When I get the low battery warning, I connect the AC adapter but when I switch the power on, the laptop screen goes blank. The DC in LED lights up, the Power LED stays on and the Battery LED comes on but I cannot use any keys on the keyboard, the laptop has frozen. Any ideas?

Does this happen when you connect the small plug directly to your laptop or the mains plug?
I noticed similar problems (usually shutdown) when connecting/disconnecting the mains plug. This does not occur when the power adaptor is plugged in and I plug the power connector at the laptop in/out. I guess there is a problem with the transient behaviour of the power adaptor & the power detection in the laptop.
This applies to Satellite M60. I recall no similar issues with an older Sat 3000.

No low battery warning, just shuts off

I have an Core Due Macbook back from September 06, and recently I've stopped getting that low battery warning message. Now my laptop will just shut off at 20min (sometimes even 30min) without any warning. I tried recalibrating the battery, it solved the problem for one charge (I saw the warning message once) but after that it went back to shutting off at 20min again. I've heard that Apple has extended their battery coverage, but my laptop is at 315 cycles now. I do have the extended warranty though-will that cover a replacement battery?

Hi. Recalibrating the battery does not prolong battery life. It will only help in getting a more accurate battery charge when using the computer on battery power alone. What you can do is make sure that you have the battery update and latest software from apple. Also, try resetting the SMC of your computer. Here are the links for more info. Hope these help.

My macbook pro running snow leopard updated a while ago, and now the low battery warning just pops up every 10 seconds even after I click ok, unless I plug it in. HELP!

Does anyone else have an issue of their macbook over warning? I like getting a warning when I'm at like 15%, 10% 5% and 1%. But the warning shouldnt be coming back the second after I click ok. It is extremely annoying!

No low battery warning and shut down

My MacBook is no longer showing the "low battery" warning and even with the batery status showing charge suddenly shuts down. If I check manually pressing the button of the bettery flashes 2 or 3 lights.
I have calibrated the battery several times but i am having problems doing it again because after the shut down there is still charge in the battery.
I have OS X 10.5.8 and all the software updates done.
Thanks.
Dan

Same Problem is happening to me. I have a Late 2008 13" Aluminum Macbook. If some one knows what to do please post. Thank you

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?
THX

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!

No "Low Battery" warning on new (November 07) MacBook - Kernel Panic

Hello,
I'm not sure is this is the right forum for this, but since the problem occurs during a specific battery state, I'm going to post it here.
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!

I'm a little hesitant to force a firmware update on a MacBook it wasn't meant for. These are brand new models, and I would think Apple didn't ship them with the known faulty batteries or bad firmware.
The frustrating thing is I have no way of knowing who the culprit is. Is it the brand new OS that I'm sure has a fair share of bugs? Is it the new hardware having a power control issue? Or is it a combination of Leopard and the new hardware? I was hoping to find some users who had the same problem so I could narrow it down. Battery drains out, kernel panic, then the machine shuts off after a few seconds. Funny thing is, the indicator says I have like 10 minutes or so left, but it appears that the battery must be completely dead, since it forces a panic and the machine just dies. So it might be a calibration error. The Mac thinks it has some juice, but in reality it's just about dead.
I made an appointment for the Apple store tomorrow, so we'll see what they have to say. It's otherwise running beautifully, thankfully.

In the course of migration MacBook switched off due to low battery. After recharging progress bar doesn't change.

In the course of migration MacBook switched off due to low battery. After recharging the progress bar doesn't move. How to continue the migration?

I've never seen the Migration Assistant resume from sleep - for that matter I've never seen a computer go to sleep while MA was running. (If there's a next time, don't try this without the computer being plugged in.) You will probably have no choice but quit the migration and start over.

No low battery warning on new Macbook Pro (Mid 2012)

Hello!
I just purchased my macbook pro this saturday and it's my first mac. I've noticed that I do not receive a low battery warning at all. What can I do about this?

Thanks for the battery info, but the steps for calibrating the battery don't apply to current laptop models.

Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article.

Low battery warning comes on too late?

Hey guys. I've been having this problem where the computer shuts down like 20 seconds after the reserve battery power warning. I literally dig into my backpack for it as soon as the warning pops up, and then as I'm plugging it in, it shuts off. The point of having the warning is to give me enough time to plug it in. Is there a way to change when the warning comes on? Say, at 15% instead of 7%? And isn't it supposed to go to sleep, not shut down? Because mine is completely shutting down less than half a minute after the low battery warning.
I'm running a 2008 Macbook Pro and have a brand spanking new battery and battery charger that I bought from the apple store about 2 weeks ago. I remember the low battery warning used to come on at around 9% when I first got it, and then it would still run a good 15 minutes after that before going to sleep.
Also, I am running it on higher performance, not better battery life. Oh and I'm still on Snow Leopard. Let me know if you need any other information. Thanks in advance.

think your battery is bad but you can also try the smc & pram reset.

PRAM: Hold Command Option P R at startup until you hear the chime twice.

Low Battery warning at 90%

I have a G4 ibook, that didn't get used for a long time, (over a year) and I am using again after my newer laptop was stolen. The battery may be near the end of it's life, but I am confused by getting a "low battery warning" dialog box, when the battery indicator says 90%.
If it was just dropping quickly I'd assume the battery was toast, but I don't get the conflict between the two pieces of information.
Is there any point in resetting the PMU? Should I just consider this a not-so-portable until I replace it?

Have you tried calibrating the battery?
Calibrating your computer's battery for best performance
If that doesn't help, resetting the PMU may not help, but it wouldn't hurt.
