No sleep but shut down when battery drained

Hi there,
just bought a new battery for my MacBook - what happens now is that when I get the battery drained alert (10 min) my Mac quits just about 2 minutes thereafter. Unfortunately it doesn't go to sleep so I have to reboot it after connecting it to power...
Any thoughts? Thanks!

macbig, you haven't read much about recent Apple notebooks, have you? All portables since the first white MacBook has had a 'Safe Sleep' mode, which is supposed to activate automatically when battery power drops below a certain level. Active memory is saved to disk, and the computer shuts down all power draining activities. It is then essentially completely off. The difference between this and a standard shut down is that when the power button is next pressed (with a power supply connected), the system resumes after a short wait, with everything still open, just as it was left. This is very similar to a Windows PC's hibernation mode.
What the original poster here is describing is the problem I am having which brought me here. The safe sleep mode fails to activate, whether the system is active or sleeping. It instead just shuts down hard, as an older model would. In my case, this behavior has been intermittent since my original purchase a year ago. I have calibrated my battery, reset the power management unit, and all the other recommended fixes. My battery is in excellent condition, and in my case, this shutdown doesn't occur until the indicated level is actually at 0%. Nevertheless, it is a feature which is supposed to work, but doesn't. I'm hoping someone else here has experienced this and found a cure.

Why does my iphone 3gs shut down when battery gets to 80%? have installed new battery and nothing changes?

Why does my iphone 3gs shut down when battery shows 80%. a couple of months ago is shut down at 60% but has continually gotten worse. this was before 5.0. i took it to a repair man and he tried a used battery, a new battery, and the original battery. nothing helped. 5.01 didnt help either. What is my problem?

Fully discharge the battery (till it shuts down and won't turn on) and then fully recharge it (100%). This will recalibrate the battery meter. You may need to do this a few times.

Cannot sleep or shut down when connected to TV through DVI

I recently reinvigorated my 2003 Power Mac G5 (Power PC) with a clean install of OSX Leopard and connected it to my TV via a VGA cable and DVI adapter. I soon discovered the computer would not sleep or shut down with the TV connected:
- Selecting "sleep" from apple menu, OR
- Pressing sleep button on original ADC monitor (with both monitors connected,) OR
- Waiting for 15 minute automatic sleep mode:
computer sleeps (tower clicks off as normal) but immediately wakes again
- Selecting "shut down" from apple menu:
computer shuts down completely but immediately reboots
When the G5 runs on only the original monitor, sleep and shutdown commands work as expected.
Aside from unplugging the DVI adapter every time I want to sleep or shut down, is there a solution to this problem?

I've seen the TV problem before, not sure there is a cure, but perhaps one of these...

Macbook only shuts down when battery is flat and date and time revert to 2008

Hey Guys
My Macbook only shuts down when the battery goes flat.
When I switch it back on everything seems to be fine though the date and time are incorrect. Seems to go to default date which is 2008.
Other things seem to affect my browser, Facebook won't login properly and certain websites seem to propmt that the website can't be trusted, which is strange because gmail is one of them and should be fine.
Appreciate all the help from you cyber friendly folks!

To answer your questions in sequence:
1) You can't, really: the symptoms your Mac is exhibiting point at a loose or next-to-dead back-up battery. Only way to find out is to test it, and to do that, you must open your machine, locate the battery and test it with a battery tester (see here for more info on how to open your Mac; make sure to select the right model)
2) It's actually the opposite: when you must use your Mac on the battery, well, then, do it, but if you're sitting at your desk, or, like me, on your sofa, with your MBP on your lap, simply keep it plugged into the main.
An additional measure to preserve your battery, that applies less to the recent Unibody design, but is helpful for ealier adopters of the MacBook Pro: don't leave your machine plugged in when it's turned off; it prevents a slow, natural depletion of the battery, and will play against you in the long run.
Last but not least: battery calibration is required once a month for older MacBook Pro models (non-Unibody, basically). If your machine belongs to that era kids the age of Justin B. don't even imagine ever existed, check here.

IPhone 5 keeps shutting down when battery is stating good battery strength.

My iPhone 5 has been regularly shutting down when the battery percentage is showing random charge. Sometimes it shuts down at 20% and the highest has turned off at is 73%. It then says battery is empty and needs recharging, but when phone turns on again it says the battery percentage that it turned off at. Today, the phone was charging for 6 hours and it still said the battery was empty. It finally turned on after another 6 hours but battery said 26%. Is this just a need for a new battery or something more seriously wrong with phone?

I'd just like to say that ahs70's post on Dec 1, 2013 at 1:17am on Pg. 9 worked for me as well: https://discussions.apple.com/thread/5338609?start=120&tstart=0
If your iPhone's battery is acting up you need to determine if it's a software issue or a hardware/battery issue. To do that, after syncing your iPhone, erase/hard reset all data and settings from your iPhone to what it was from the factory as new. This can be found in Settings/General/Reset/Erase All Content and Settings. Then test it out for a day or two. If it's still acting up then it's likely a hardware issue and you will need to get your battery replaced. If your warranty is done than check out this link to get a battery kit to replace your iPhone battery yourself: http://www.ifixit.com/Store/iPhone/iPhone-5-Replacement-Battery/IF118-001#produc tDescription
If your iPhone is now working properly after hard resetting it than it's most likely a software issue. This battery issue only started after upgrading to the new iOs7, so it is obviously related to the update not properly installing itself. What has worked for me and many others is to manually update to iOS 7.0.4 using the full downloaded version of the update which is about 1.32 Gigs.
But first you need to find out what model of iPhone you have, click here to determine if it's GSM or CDMA: http://support.apple.com/kb/HT3939?viewlocale=en_US&locale=en_US
Then go here and scroll down to download the iOS 7.0.4 complete update for your device: http://www.downloadios7.org/download-ios-7-0-4-ipsw-file.html
Then scroll up on the download page and follow the instructions of updating your iPhone manually following the instructions below: "IPSW with iTunes"
And your done.
Problem solved.
I only posted this because it was a very frustrating problem that no one really seemed to figure out a solution for.
I hope this helps.

Ipad shuts down when battery is at 20%, since updating to 7.0.4

I've read a few posts about battery issues and I've tried everything from battery saving tips, to resets, to restoring my ipad. Nothing is working. My sister also has an ipad 2 and has exactly the same issue except hers shuts down at 35-45%. This is only since updating to iOS 7, possibly only since iOS 7.0.4.
Can anyone help? Apple? Why can't we roll back a version any more?
My ipad is out of warranty and I don't want to pay for a new battery when it seems to me to be a software issue...
All replies appreciated.

Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

MBP shuts down when battery at appox. 30%

Hello,
I have a 17" MBP 2.33GHz Intel Core 2 Duo.
Recently (in the last 3-4 days) it has decided to shut down completely when the battery charge falls to around 30%. Prior to these symptoms appearing, it behaved normally with the 'low battery warning' appearing at about 5% and then going to sleep mode as opposed to shutting down.
I have reset the SMU by removing the adapter, battery and pressing the power button for 5 secs. Unfortunately the symptoms remain. Obviously I cannot re-calibrate the battery as it won't carry on below 30% charge without the MBP shutting down.
I'll be taking a trip to my local Apple dealer in the next few days but was wondering if anyone else here has any further suggestions I could try.
Many thanks in advance.

Umm... of course Apple will do something. I do not understand why you felt you had to add that to your reply. Allow me to explain:
1. I have AppleCare, therefore if it's a hardware issue then any repair will be carried out without any cost to me.
2. Apple have introduced a 'battery exchange and extension' program:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
If the battery is at fault, regardless of whether I have AppleCare or not, the battery will be replaced as it falls within the terms of the extension program.
I have just now reset the PRAM and am running on battery power. I'll know in the next couple of hours whether that has had any effect or not.
Meantime, if anyone else has any additional suggestions as opposed to 'me too' type replies I would be very grateful.
Many thanks.

Computer Shuts Down When Battery Gets Low

I have a few interconnected issues and one peripheral issue:
1) When battery charge gets down to between 20% and 10%, by MacBook shuts off. It doesn't go to sleep. It just shuts off.
2) Battery loses charge quickly (I get about 1.5 hours of use out of it, which is no good for a machine that's a year old, right?)
3) I think the machine runs to hot and fan gets too loud.
The above all occur when set for "better battery life" and when doing light web surfing, ichat, and playing music in itunes. I did the firmware update and no change to these problems.
Then there's this...
4) Distorted screen, specifically horizontal green lines, when trying to watch a DVD through FrontRow.
Anyone experience this? I just am curious what to expect before I take the machine in...again (it was treated for RSD).
MacBook Mac OS X (10.4.6)

I'm running on battery now.. saving all my work diligently pretty much every minute on the minute... currently 1hr 42mins remaining of battery life - so it says.
This compleatly unnanounced shut-down has happened twice to me now, and it's very disconcerting. This is the only problem I've ever had with my MacBook (bought it August last year) and is annoying as I KNOW it was this 'update' is responsible. I lost about 40 mins of work because of this yesterday and am pretty annoyed about it frankly. My battery seemed fine before hand - I actually was typing away happily on it in the back of a four hour car journey just last week, eeking out the charge by turing the screen right down etc. SURELY if this is known, and is obviously software/firmware created, Apple can offer a similar patch to correct it??
I'm in the UK and a day-trip away from any Apple Store. Do I have to phone Apple and ask for a replacement battery? Is that how it works (like I said - I've never had technical difficulties with my MacBook previously). I searched the site and found this number: 0870 876 0753, I think that's right. What should I have ready on the phone?
REALLY hope this can get sorted soon as I can't really trust the machine at the moment without it being plugged in, making taking it out anywhere (which is why I got it - and loved it) pretty redundant.

Macbook pro shuts down when battery reaches 90%

Ever since I installed iOS, both my Macbook Pros have started showing the same strange behavior. On battery power, they suddenly shut down even when there is still supposedly plenty of power left. Last night one of them (the newer one) shut down at 90%. the other shut down at 75%. Any ideas?

I really hope that sig doesn't work for Apple Support... or at least he doesn't anymore.
Allan, sometimes people make mistakes speaking technical words, specially if those are Apple achronims. What differentiates a good answer from a waste of time is when one makes an effort to understand what the other is trying to say and gives a potential solution.
However drmezan, has wasted his time with you two explaining his problem until he got the question corretly formulated, and when at last he manages the way you like it... none of you reply... is this a joke?
Are you kidding people here or what?
drmezan:
I'm suffering the same situation here, however if I plug it to the power supply it doesn't shuts down.
Would it be related to the temperature ? It's true that my Mac Book Pro gets really hot quite quick, but it only turns off suddently when running on battery.
Any help would be appreciated.
Thanks.

IBook G4 1.42 GHz shut down when battery storage is lower than 60%

Hello everybody.
My iBook G4 has been used for 10 month and updated to OSX 10.4.6. Three days ago, it shut down immediately without any warning. After this experience, I checked the battery information at two situation:
Battery is charged:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 2946
Remaining Capacity (mAh): 2935
Amperage (mA): 0
Voltage (mV): 16615
Cycle Count: 189
Battery is about 60% storage:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 2946
Remaining Capacity (mAh): 1764
Amperage (mA): -1825
Voltage (mV): 15438
Cycle Count: 189
I am sure that the voltage and remaining capacity of the battery before the sudden shutting down are reasonable, just like what you can see above, and the LED indicator on the battery sitll indicates 3 green light.
I have already reset the PRAM ,NVRAM, and PMU successfully, but the sudden shutting down still exists. If the AC power is plugged, everything will be ok.
Can someone resolve my problem? Please forgive my poor English. Thanks a lot.

Try another battery. Since you have calibrated your battery weekly, it may need to be replaced. (Apple recommends monthly calibration.)
The typical lifespan of a lithium-ion battery is two to three years. Some last a bit longer, but some don't last that long, either.
It may just be that your battery needs to be replaced.
From that Apple page on batteries:
A properly maintained Apple notebook battery is designed to retain up to 80% of its original capacity after 300 full charge and discharge cycles.
Click on the Apple icon in the top left corner of the display. When the information box pops up, click on "More Info…" The System Profiler will appear. Click on the Hardware disclosure triangle (if necessary). Click on Power. See how many cycles your battery has used to determine if your battery may be eligible for replacement under warranty. If it has less than 80% of its original capacity with 300 or fewer charge cycles used, you may have a case for asking for a replacement battery without cost to you.
Good luck.

Unexpected iphone shut down when battery level is 100% at point of call (making

Hi, I need help. My iPhone 4 (bought 3 years ago) shuts down unexpectedly. At first when the battery was still 30%full, but then it got worse and now I can't use it anymore only when I'm connected to power. I restored it in the hope it would help, unfortunately not!. It happens when getting or making a call even at 100% charged even while receving massages.Is it a battery problem??Please help

Why are you doing this? This is completely unnecessary and in fact "may" be damaging your battery. Fact is, lithium-based batteries do not like to be completely discharged on a regular basis. Apple only recommends you do this once a month. Read more here:
http://www.apple.com/batteries/iphone.html
This type of battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided. Instead, charge the battery often. Full discharges put additional strain on the battery & will shorten your battery life.

Phone keeps shutting down & unexpected battery drain

I'm having the same issue, my phone is just 3 days old but it keeps shutting down frequently. When I press the power button it doesn't get turned on, I called customer service who asked me to press power button +volume rocker which turned the phone on. However the main problem still persists -shutdowns frequently. Extremely disappointed with Sony

Iphone 5 shuts down when battery life still shows 10% left

Install iOS7 on iphone 5 and the device will power down sometimes when it still shows 10-20% battery life then not power back on, while displaying that it should be plugged in. Also the phone will sometimes jump from 20% life down to something like 1-3% on the indicator in mere seconds and powers off shortly thereafter.
Basically the phone gets down to what shows as 20% battery life and may shut down at any point after that....

This could be because the battery has not been properly calaberated try the link below. http://www.apple.com/nz/batteries/iphone.html

Computer shuts down when battery is at 45% used

When running on the battery the computer shuts down completely when the battery shows about 65 % left. Then I have to use the command start to get it going again, any thoughts?

Welcome to Apple Support Communities
Reset the SMC (System Management Controller) and re-calibrate the Battery - make sure you do this re-calibration every 2-3 months (I'm guessing you've never done it?)

Macbook slow and shuts down when battery indicator is not empty

Hi everyone,
I have a 17'' macbook pro bought mid June 2007.
Three weeks ago I noticed that my macbook pro would shut down at 20% battery (if I was not plugged) and would not start back until I plugged it in. I figured it was a battery problem. However, my macbook started getting really slow with the little 'volleyball' icon appearing more and more often without having to use lots of different of programs in parallel.
Also last week I realized that now my macbook pro shuts down automatically at 67% battery! I checked the little button behind the battery and when this happens it shows to me 3 out 5 light indicator. So I'm guessing that the battery is not dead and yet my computer shuts down.
I resetted my SMC (I think that's what it's called) and repaired my disk... I have not reformatted it though.
Can someone help me out? Is the fact that my mac is slow related to its shutting down prematurely?
For info: my battery is 2y old and has 360 cycles.
Thanks a lot in advance for your help!
Cheers
aqualover

Good on resetting SMC.
You should properly calibrate your battery:
http://docs.info.apple.com/article.html?artnum=86284
If that doesn't fix the problem, contact AppleCare about a replacement. Battery warranties were extended to 2 years and maybe you still have a warranty:
