MacBookPro shuts down with no low power warning.

Once my battery drains to around 10%, my mac just completely shuts off, with no warning. In the past, I had received a warning.
I've reset the SMC several times. I've reset the PRAM/NVRAM several times. This has had no effect.
The shutdowns are occuring both with an Apple branded battery and with a 3rd party battery.
I've only recently noticed this problem, because for a long time I've been using my laptop more like a desktop, completely on battery. Once I went back to using it as a proper laptop, I began to experience these warningless shutdowns.
Any advice besides trying to reset the SMC and PRAM again and again?

I've fixed the problem and want to share my solution.
I suspected some corrupted system files, so I reinstalled Lion (command-R at start up followed by a large download). This was extremely easy over a T1 connection and resulted in the low battery warning messages reappearing. But the mac still unexpectedly shut down instead of sleeping when the battery got too low.
So, I did another SMC reset, figuring it might have an effect in conjunction with the newly installed Lion. It worked! I now see low battery warning messages (at around 6%) followed by sleep (at around 4%).
I hope this info might help someone else.

MacBook Pro Shuts down when battery low without warning

Hi
My MBP has been quite power efficient. However, for the last 3 days (since I installed the Mac Update to 10.4.7, I think) when the computer runs on battery the computer switches off without warning. This happens when the battery power is about 25%. It wont restart until I connect it to the AC adapter. Upon start up the battery level is 22%.
The computer doesn't go into sleep or warns it just up and quits.
Any suggestions?
Thanks

Same problem here with a 17" MacBook Pro that I have had less than a week. Just last night it started doing it. This is so frustrating, especially since it's a week 25 model. At 28%, it shuts off with no warning, and pressing the button on the battery shows no charge (no lights come on). It was working fine before, and I had already tried resetting the PMU and calibrating the battery.
I called AppleCare, and the lady I spoke with had to do some checking, and I waited on hold for a long time. When she got back, she told me that she had spoken with a product specialist and that my serial number wasn't covered by the battery recall. She then tried to tell me that the computer shutting off by itself at 28% is "normal behavior," and I should make sure to keep my battery charged up and not let it get that low. She went on to say that the battery isn't covered by the warranty, so she couldn't send me a new battery and I should take my computer to an authorized service provider (the nearest of which is 80 miles away) to have them diagnose the problem.
I told her (nicely) that it is most certainly not normal behavior--it's unacceptable. So she put me on the line with a product specialist, who I had to convince that there was a problem with my battery. I told him that the full charge capacity has been fluctuating all over the place and that I've been getting poor battery life (due to the fluctuating capacity combined with the computer shutting off at 28%).
He said that even though my serial number wasn't covered by the battery recall, he would send me a new one. And of course I had to give him my credit card number to ensure that I returned my old one.
Anyway, hopefully the new battery fixes it for me. If I can remember, I'll update on my situation in case anyone's interested.

Ipod mini- 3/4 battery shutting down with "no battery power remaining"

After fully charging my ipod mini, while it still has 3/4 battery on the battery meter in the corner will shut itself down due to "no battery power remaining" if i push the NEXT button too many times in a row. This is a consistant problem and always happens when i have a half battery power or more. I do keep it in Shuffle mode, and i am fully aware that will drain the battery quicker, however there should be no reason a freshly charged ipod with 3/4 battery should not be able to shuffle a few songs without shutting down. Has anyone else ever had this problem or knows of any solution for fixing it? Any help would be appreciated!!

my ipod is doing the same thing...except when I turn it on it will say i have 3/4 battery for only about 10 seconds, then it turns off. All the other forums I have read say to get the battery replaced, but Apple can and usually does send a faulty battery so it might be time for a new ipod.

Snow Leopard shutting down with no warning is getting more complex!

I have a series 1 Macbook Pro and have updated to Snow Leopard. As with most other people I immediately got problems with the "battery Service" message. So, having read all the various posts, and tried re-calibration, I bought a new battery.
Charged fully and disconnected adaptor. The machine shut down with no warning at about 85%! I tried a few more times after fully charging the battery and it shut down a number of times - 83%, 85%, 89% and 98%. The battery shows a cycle count of 1. The last time it shut down (89%) I decided to try re-starting without plugging the adaptor back in. The machine started and ran up to the point where it properly started Snow Leopard - when it was about to change from the blue screen - at which point it shut down again. I tried this a number of times and it was absolutely conisistant, doing it every time.
I then had the bright idea of plugging in the adaptor but watching the LED to see what happened. The LED came on green for 1 or 2 seconds, then went red. I then immediately unplugged it again. I then tried to start the machine with battery only. It started perfectly and went on running until down to 15% at which point it shut down, again with no warning. Tried re-starting - it wouldn't! Plugged the adaptor in so that it would charge the battery whilst using the machine. Then, much to my amazement, while the adaptor was still plugged in, and the battery was far from fully charged, the machine shut down - again without warning. That's "it shut down with battery installed AND mains connected". The machine then wouldn't start, with mains connected. It would switch on for a few seconds then shut down again. To get it to start I needed to remove the battery and run it on mains only.
That's where I am at the moment, running 'mains only' with no battery installed. It looks as if Snow Leopard sets the battery monitor / charging hardware incorrectly on the MBP. Once set incorrectly it looks as if it loses itself!
Has anyone else experienced anything like this?

It really doesn't get any better! Well, not a lot. I decided that I'd try yet another brand new battery. I charged it fully, disconnected the mag connector and it ran happily without shutting down - hooray. However, after putting out the message about low power and about to shut down, at about 5%, it ran to about 2% and shut down without warning. It didn't go to sleep.
I then couldn't get the machine to start again. I reset the SMC and still no joy. it would start to run, flash the screen a couple of times and then die. To get it to run I had to disconnect the battery, start it, then plug the battery back in again. Snow Leopard does appear to do something odd with the charging hardware. It appears to leave it in an odd state.
You may be right about Battery Update 1.3, but there appears to be no way of installing it under 10.6.8 - unless you know something I don't!

Computer shuts down with charge on battery and no warning

without warning and plenty of charge on my battery my mac book pro shuts down? if it just sits there in sleep unplugged it seems to run fine, but if its unplugged and i try to use it (with a charged battery) it shuts down with out warning. started about 3 months ago. Is the battery just old..?

It is almost certainly a sign that your battery is dying, timskins.
The problem is that when batteries deteriorate their internal resistance increases and they are no longer able to deliver power when it is demanded, even though they still have the ability to store it. They may chug along providing low power for quite a bit longer, but when your computer suddenly needs a bit more (because of increased CPU or GPU demand, or the HD spinning up or whatever) it is unable to provide it and the computer shuts down unexpectedly.
Think of it like driving a car with a bad fuel pump. Your car is driving along a highway with a full tank of gas. Its running smoothly enough. You put your foot down to accelerate up a hill or overtake a another vehicle and the engine dies because the fuel pump can't meet the greater demand for gas. The tank is still pretty full but the fuel can't be pumped in fast enough to keep it running in a high demand situation, so it shuts down.
See the section dealing with increasing internal resistance in batteries at http://www.batteryuniversity.com/parttwo-31.htm for more about such things, or http://www.buchmann.ca/Chap9-page1.asp for a longer, more technical, account.
Once this starts happening the only options are to get a new battery or to avoid any work that makes much demand on power (like visiting a "Flash" based website or, when it gets bad enough, even spinning up the HD from a stationary situation.) Unfortunately even with light use the battery will soon reach a point where the regular peaks of CPU and HD use will become too much for it and you will suffer more and more unexpected shutdowns until the battery is replaced.
My suggestion would be that you take the battery to an AASP or Apple Store, where they can quickly "stress test" the battery for you to make certain that in your case this is, indeed, the problem.

Satellite L40 won't shut down with power connected, and won't go in standby

Hi everybody. I hope someone can help me. Basically, there are two problems: one with shutting the laptop (Satellite L40-17U (Vista 32-bit Home Premium SP1) ) down when the power is connected, and one with closing the lid and putting it to sleep.
1. Since a few weeks, it suddenly doesn't want to shut down, whenever the power is connected. When it is on battery, it will shut down. When the power is connected and I try shutting it down, it seems like it shuts down (all activity ceases and the LEDs go off) for about 1 or 2 seconds, and then it goes back on.
2. When I close the lid (all settings in Vista are set to put the laptop in 'sleep' status when the lid is closed) the laptop goes into a state from which it can only be recovered by shutting it down by pressing the on/off button for about 10 seconds to completely shut it down. When closing the lid, only the battery LED keeps blinking orange (the way it should be), but apparently the laptop keeps consuming power, because when I reboot it later (first having to shut it down as described above) the battery tends to be quite a emptier than it was before rebooting it (like going from 100% to 65% in 30 minutes, while being in 'sleep' state). Also, when I open the lid, the other LEDs do go on again (green), but nothing happens.
After rebooting by first pressing the on/off button for 10 seconds to shut it down, I frequently get a message that Windows could not be started, and have to run System Repair.
I've just done a completely clean installation with the product recovery CD (didn't install SP1 yet), upgraded the BIOS to v1.90, but the problem remains.
I'm afraid my only option will be to bring it away for a warranty repair, but knowing that these repairs can take weeks, I'd prefer to try a solution anyone here could recommend me first. If you have any ideas, please let me know.
Thanks,
Daniel Breslauer

Hi guys
Never had such issue on my notebook but regarding to another users here in the forum the BIOS might help to solve such strange notebook behavior
To be honest the shut down issue is not known to me I noticed an standby issue on my notebook but the BIOS update helped.
Therefore I recommend updating the BIOS firstly.
If the issue will still appear, then the ASP should take a look into the notebook.
Good luck

Hi,
Troubleshooting a start up script can be difficult. There are some third party programs that also keep logs of start up programs, however for Firefox this may be different.
Is Firefox a startup program? [http://www.winxptutor.com/msinfo32.htm]
Its also possible to check the Web developer tools for any scripts in a page: [https://developer.mozilla.org/en-US/docs/Tools/Debugger]
In the control panel there is also Administrative tools to view event logs, but this may be something a local technician can walk you through.

Hp 300-1223 window 7 want shut down with power also the screen black

all in one 300-1223 that want shut down with the power button every still run's and the scrren stay black when power up .Using window's7. Help please

It could be the power supply, shorted device of any kind attached (bad printer, flash drive, keyboard, mouse, network connection), memory problem, video card fan not spinning and the video card could have overheated, bad capacitors (rounded or leaking a brown or dark substance). The first think you should do is make sure it is not under warrantee. If it is, contact HP. If it isn't, remove the cover and inspect the board for bad capacitors, fans not turning, disconnect all non essential items like the hard drive, DVD, floppy if you have one, all external devices (yes the monitor) and turn on the computer. Does it appear to stay on? If yes, shut it down by holding in the power button for 5 or more seconds or flipping the power switch on the power supply or pulling the plug. Connect the monitor and then one item at a time leaving the hard drive with your important data as the last item. If it didn't stay on. Try to use only one piece of memory and try each memory slot, try the next piece etc. If that doesn't work, the best guess is the power supply (if you have an ohm meter - test the power supply first). You can run a anti-virus/adware/spyware check by removing the drive and attaching it as a 2nd drive on another machine. You could also run a check disk while it is there. I like to download the hard drive manufacturer's disk certification test iso image and make a bootable cd. Boot off the cd and test your drive. It can fix bad sectors and some minor drive problems.

Shutting down (with warning). Now dead.

I have read about other people's issues and this one seems slightly different:
My 15" G4 PowerBook Titanium seemed to be running fine. The battery (not included in the recall) had a normal charge. But then it was like I pressed the power button and that window poped up asking "are you sure you want to shut down"? I would race to say NO and some times it would work and sometimes it wouldn't. But then it would start back up so I didn't take it in (or take it seriously).
This went on for about a month until one day it shut down - with a sound. It sounded like one of those Emergency Broadcast System beeps. You know, long and steady.
I removed the battery and it started up for a second. Then it shut down agian (with out a sound this time).
It is about 3.5 yrs old and not under warranty anymore.
Anyone got any ideas?
G4 PB 15" Mac OS X (10.3.1)

If you go to http://www.versiontracker.com/macosx and search on 'battery' you should find a battery status program that will tell you how many cycles you have. (I don't believe Panther included battery cycles in the system profiler).
If you haven't already, you should read this Apple article http://www.apple.com/batteries/notebooks.html . Lithium batteries should be discharged about once a month.
If you took the battery out and the system doesn't work with the power adapter plugged in, either the power adapter isn't working, or there is a logic board-related issue. Run your Apple hardware test to see if that indicates a problem. Insert your first OS X CD, reboot holding the option key down, choose Apple hardware test, follow directions, and choose the extended test. Does it indicate any issues? You can also use TechTools deluxe or Pro if you happen to have one of those programs.
Sometimes resetting the Power Management Unit will help. Directions at http://docs.info.apple.com/article.html?artnum=14449

Computer Shuts down when on battery power at 80%

The battery power indicates anywhere from 80% to 90% and will shut down the computer.
No warning, No Low Battery indicator, No error messages.
The only way to boot up is to use the power adapter.
I have tried to reset the computer
I have tried to update the latest battery update, but it tells me it is already installed.
This computer is 8 months old.
Is there anything else I can try?

I had/have this exact same problem after I installed the battery update 1.3 on Macbook Pro a few days ago.
I tried a SMC reset & a PRAM reset, all to no avail.
I called Apple today & talked with 2 different agents explaining my problem. One askked me to do another PRAM reset, which I did, again, to no success.
So, they are sending me a new battery, which I am really hoping will solve my problem (Macbook Pro shutting down instantly on an almost full battery at around 84% while not attached to the power cord).
Thing is, I never had a problem with the battery before I installed this update, so this battery update 1.3 somehow corrupted my battery/settings, and unfortunetly once you run this update, your stuck.
There is no way to undo this update as it changes the firmware permanetly.
Ugh.
Next time, I am not going to be so quick when installing "updates", I apparently really don't need. This battery update 1.3 has just caused me headaches & problems on my new Macbook pro.
Heed my advice. Research firmware updates carefully before subjecting your computer to these unneeded "fixes".
My advice is to call Apple & let them know of this problem. Get a new battery. They were apparently unware of this problem update when I called today, and more people need to be vocal about this & complain about this apparently corrupt battery update.
Good Luck.

Macbook Pro shuts down with 40% battery left... does not just go to sleep

Hi,
Our MacBook Pro has started to shut down with about 40% battery left. After it has shut down, I press the button underneath the computer and 2 our of 5 lights light up on the battery. I wouldn't mind if it just went to sleep but I totally have to restart it and lose everything I have been working on when it died. The computer used to go to sleep when the battery got to 0%, then I could plug it in and keep working.
I don't know if it's a software issue or a battery issue or a firmware issue.
Any tips would be MUCH appreciated.
Thanks a lot.

I have read so many articles across the internet with people experiencing this problem. This is the conclusion I came to.
I could not calibrate my battery as my system would hard power down before it got anywhere close to draining the battery entirely. The last 10 cycles on my battery were attempts at calibrating. The most common cause would be because the battery in our macbook pro does contain something close to the charge being reported by the computer, but cannot deliver it. Your fuel gauge is probably not incorrect, especially when the leds on the battery itself show a charge that should be capable of running the machine. Even if it is not calibrated correctly. The internal resistance of the battery itself has compromised the batteries ability to deliver the amperage necessary to run our machines. After finally realizing this, I turned my screen brightness all the way down, and sat all my power settings to max battery life without allowing the machine to go asleep. Then, I went to sleep myself =). In the morning it appeared as though I had a successful calibration and the machine did not power down hard. Depending on how bad of shape your battery is in, this may or may not work. Either way, it didn't matter much. Even with my fuel gauge being correct, if my screen brightness was cranked up and I was doing anything somewhat processor intensive, my battery failed to provide the needed amperage and powered down my system hard again.
The battery really does have the amount of power it says, it just cannot deliver it as fast as needed. At a slower rate, it will work. A replacement battery is needed. I cannot explain the strange jumps/dips in storage capacity but would guess these numbers are a guide, and more than one environmental factor can change this number. Also, once the internal resistance builds up inside the battery and the inability to calibrate happens, it compunds the problem.
My machine is a first gen intel macbook pro. A few months after I bought it, I had battery problems and apple replaced my battery. My machine is 31 months old, it's battery is somewhere around 27. I tried to get apple to replace my battery and they told me no. I was 40% healthy @ 207 cycles. Many people complain about this but it seems reasonable to me, I didn't argue. I do believe my battery failed prematurely, however, it was due to a few factors and I do not think it was the batteries fault. My machine was one of those nice overheating first generation macbook pros. To make the matter worse, one of my internal fans stopped working. I knew this as my istat pro program showed me 1 fan @ zero rpm. I figured I had applecare and had work to do, so continued to use the computer for several months. I did quite a bit of video encoding and processor intensive work. When I would get to work in the morning, my granite desktop was really cold, however, after a half hour or so with the macbook pro running the heat would dissipate through it and warm it up nice and comfortable! lol, some may not think this is funny, but it worked well for me. I frequently had over 180 degree cpu temps and the bar above the keyboard being too hot to lay your hand on and keep it there. I am sure some of this excess heat contributed to the premature failure of my battery. The type of batteries in our machines are killed by heat, charge amount, cycles and age. Probably in that order for most users. So, can I blame apple because my unit ran hotter than it should have because their fan failed! eh, maybe, but I am happy with this laptop overall. I have never had a single laptop for more than 15 months and have had this one for over 30 now.
I ran across this site somewhere, it may have been another user on these forums, I cannot remember. http://www.batteryuniversity.com/partone-19.htm On this page, it talks about our batteries, the effects of heat and level of charge in combination with age. At 77 degrees F., charged to 100% (which is very typical of our machines, or close to it) after one year the battery is 80% as good as it was when it was new. At 32 degrees it is as 94% as good as new after one year. Jump up to 104 F. and the battery is only 65% as good as new after 1 year. Sometimes my computer is running for days and sometimes the environment is warm. Add that to the heat produced by the machine itself and I bet the battery sustained 100 degree temperatures for long periods of time. Just for fun, at 140 degrees and 100% charge in our lithium ion batteries, after only 3 months the capacity is only 60% of its new capacity.
Anyways, that is my battery story. Sum up. The inability to calibrate is due to the batteries increased internal resistance and inability to deliver the charge at a rate needed by your computer even though it appears healthy, or somewhat healthy. You may be able to calibrate by making your laptop drain less power, turn screen brightness all the way down, turn airport & bluetooth off, let hard disk sleep, and let it go. But that will not stop the hard shut down problem, although the fuel gauge will be more accurate. Think of it like this. a 100 gallon fuel tank on a car full of gas. The fuel gauge is correct, it is full. However, the fuel line connecting the fuel tank to the engine is made of a space age material that shrinks as it ages and is exposed to heat. Eventually the fuel line shrinks to the size of a coffee stirrer or small straw. When the motor is turned off the fuel seeps into the small straw. Start the motor, it begins to sip the fuel from the straw. Rev it up (encode video), the motor demands more gas but cannot get it. The motor stalls out (your computer shuts off). Same idea somewhat. Sorry so long

MacBook shuts down immediately both when power button is pressed and when lid is closed

Hey there,
The mentioned issues have happened to me for a couple of years or so. Specifically, when I press the power button it shuts down right away along with a click. Same happens when it sleeps; the light starts glowing and before a full seconds passes, I hear the same click and it shuts down. It started around the same time my battery died out of nowhere so I always attributed it to that. Now I got a new battery and it's still there. I tried resetting the SMC with both methods. The built-in keyboard had coffee spilled on it years ago so it doesn't really work, but I tried the key combination anyway. It didn't fix the problem, so I tried unplugging the battery and holding the power button. That didn't work either. What could be causing this issue?
Thank you.

Your problem is way more complex, here's my standard answer:
"Whenever a liquid spill occurs the first thing that has to happen is the laptop should be shut down immediately. All power must be removed as soon as possible. It is especially important that the battery be disconnected and removed.
All affected parts must be removed from the laptop. No attempt should be made to start/restart the computer since this could potentially damage the logic board beyond all repair.
Then all affected parts would be washed in deionized water and blown dry with compressed air. (In a water spill the deionized water is probably not as critical. Depends on the mineral content of the water.) and blown dry with compressed air.This is especially true of the large chips on the logic board. Water can wick under them and cause havoc.
