When my MacBook Pro i7 runs out of battery, it powers off.
I can't seem to figure out why my new macbook pro turns off when it runs out of battery. Typically, when macs run out of battery, they go into sleep mode. However mine skips this completely and just turns off. Any similar problems? any ideas?

I have an update regarding this issue. Since receiving my new MacBook Pro, I have calibrated the battery 3 times. Here are my findings of each calibration when the battery reaches 0% charge:
1st calibration: MacBook Pro enters SafeSleep (saving contents of memory to HD) and powers down (no pulsating light indicating memory is still being maintained until plugged-in or battery reserves are depleted). Plugging adapter in and powering up results in memory being restored from HD.
2nd calibration: Same as 1st calibration
3rd calibration: MacBook Pro shuts down without entering SafeSleep. Plugging adapter in and powering up results in normal boot sequence with logs indicating improper shutdown.
SMC and PRAM have been reset prior to these calibrations.
pmset -g returns the following (looks normal to me):
Active Profiles:
Battery Power 1
AC Power -1*
Currently in use:
womp 1
halfdim 1
sms 1
hibernatefile /var/vm/sleepimage
gpuswitch 2
disksleep 10
sleep 0
hibernatemode 3
ttyskeepawake 1
displaysleep 10
acwake 0
lidwake 1
I don't think this is the intended behavior for this MacBook Pro. I've started a case with AppleCare and I hope an engineer will respond to what I'm experiencing as I don't think this is normal. It appears that the MacBook Pro is not accurately determining the bottom threshold of the battery. It thinks there are reserves when there is actually none, causing weird behavior at the end of the battery charge life.
Anybody else experiencing this with their MacBook Pro 15" i7?
Will update as soon as I find out more.

I tried pressing at the same time ctrl shift comand keys to reset it and then when I try to turn it on again it just starts the screen blinks and the hard drive sounds briefly but then it dead, if you close the mac then the light that glows when is sleepeng turns on and the computer gets hot and the fans turns on and it´s stopped when the battery is dead again.
Please help its incredible, it´s my 3 mac and I never experienced this before.Thanks Sig. The information is here: Anything useful stand out?

What is application memory and why does my macbook pro keep running out of it?
what is application memory and why does my macbook pro keep running out of it?
There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
A long-running process with a memory leak (a kind of bug)
Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details. -
Is my macbook pro really running out of memory?
My Macbook Pro is almost 2 years old. OS X version is 10.6.8. Have 4GB of memory and about 250 GB disk space. Right now I still have 186 GB free space. Some weird things have been happening lately. Over a week ago, I started having problem when accessing my Yahoo mail. Sometimes it will be fine but most of the time it just hangs, the beachball will be spinning around and I have to force quit to get out. At first I thought it is because Yahoo just has this new format that is causing the problem. However, 2 days ago, the Finder just disappeared from my laptop and I had to restart to get it back on. Today when I tried to work on my 2008 Microsoft Excel workbook, I could not save it after I made changes. Excel just closed down with the message saying, 'Microsoft Excel has quitted unexpectedly'. This is a somewhat big workbook (8.4 mb) but I always have this workbook and keep it the same size so I don't know why all of a sudden I have a problem. It is true that if I worked on a smaller workbook then I don't have any issue. When I tried to save the big workbook, I looked at the Activity Monitor, the system memory had about 1.9 GB free and the % CPU would all of a sudden jumped to 100% then Excel would die. I only use my Macbook Pro for the internet, email, watch DVD, use Microsoft Word and Excel, other than that I don't do much else. Cannot think of anything that I did recently that would have caused this problem. If this is a PC I would think it's been infected with virus. I'd always used PC except this last 2 years, still don't know Mac too well to determine if this is a memory problem. I hope someone from the forum can help me out. Thanks.
Sounds like a problem with Excel, perhaps you have a Macro virus.

Macbook Pro just ran out of battery, when I tried to boot up it cannot locate the HDD.
So as stated above I mistakenly left my Macbook Pro on and it ran out of battery. When I tried to power it back on again it just goes to the folder and question mark logo. What happened? Did I kill the hard drive ?
Let it charge overnight.

Macbook Pro 2014
13-inch
Intel i5
8GB RAM
128GB flash SSD,
Integrated Graphics
iPhoto library is on external HDD
I was in a slideshow, with around 1,911 photos in it. About halfway through, my Macbook ran out of battery. Now when I restarted and charged the Macbook and reopened iPhoto, the slideshow won't advance through photos, and I can't figure out any reason why it would do this.
I thought it may be corrupted, so I deleted and reinstalled iPhoto library, iPhoto itself, and disconnected and reconnected my external HDD.
This didn't work, the photos still won't advance.
I don't know any reason why this would be happening, and there is ample space on my internal drive.
I'm happy to provide more information if needed!
Many Thanks,
JamesMake a few tests, James, to narrow down the problem and find out, if the slideshow is corrupted, your iPhoto Library, or settings in your account.
To test, if only your slideshow has a problem, create a new slideshow, just for testing. Just use "File > New Slideshow" and add a few photos. Does this slideshow play correctly?
If the test slideshow does not play either, create a new iPhoto Library. Use the File menu in iPhoto: File > Switch to library > Create New. Import a few photos and create a slideshow. Does it play?
If even a new library does not solve the problem, test in a different user account (see this document: Isolating an issue by using another user account - Apple Support):
This process involves creating a new user account, logging in to it, and testing for the issue.
Create a new standard or admin user account in Users & Groups preferences.
Use these instructions for OS X Mavericks.
See these instructions for OS X Mountain Lion.
See this video, or these instructions for OS X Lion.
Optional: If you have any specific files you wish to test with, copy (don't move) those items to the /Users/Shared folder in the Finder.
Log out of your current user account by choosing Log Out from the Apple () menu.
Log in with the new account you created.
Attempt to reproduce the issue you were seeing in your regular user account.
After you have completed testing, log out of the test account by choosing Log Out from the Apple () menu.
Log in as your regular account.
After you have completed all testing with the test user account, you may want to delete it. You can delete an account in the Users & Groups pane of System Preferences.
Note: Prior to deleting a test account, make sure you are completely done with it. If you have files in the Guest User you wish to keep, you should copy them to the /Users/Shared folder .
If you should find, that slideshows only play in a new user account, post back. -
When calibrating macbook pro in step 5 can i turn it off for more than 5 hours?
im not sure how to calibrate since i just learned that i have to do it to ensure battery life but im gonna use all the power in the afternoon and at night i will let it sleep but i dont want to wake up to charge it if it can only sleep for 5 hours.
Calibration isn't necessary in modern Macs with built in batteries. That process didn't calibrate the battery, it calibrated the circuits that monitor the battery.
From the following article:
Portables with built-in batteries
Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article. These computers use batteries that should be replaced only by an Apple Authorized Service Provider.

MacBook Pro started running slow and freezing up
Hi,
What are some things I can do when my MacBook Pro starts running slow and freezing up? For example, windows are slow to open, and that pinwheel thing keeps spinning. Clean up tips would be appreciated.
Thanks.tamyc,
You can try resetting your MacBook Pro’s System Management Controller;
You can try booting into Safe mode, to see whether it runs just as slowly (and freezes up) then;
You can try disabling your antivirus software, to see if that makes a difference;
You can download, install, and run EtreCheck, and include in your reply the output from an EtreCheck run, which might help identify software which should be uninstalled or updated. -
This has happened to me about 4 times now. I just got a brand new iPod touch (5th Gen) after replaceing my 4th gen iPod. I havent had it for a month, so its still brand new. The only thing is that when the iPod runs out of battery it turns off (duh) but it doesnt turn back on when you plug it in to charge. When I noticed that the iPod doesnt turn on, and I hit the power button, lines appear on my screen. They are lines that run up and down the screen from left to right. I try factory resets, setting resets, restoring my iPod. But this issue keeps coming up. I honestly dont know what to do. This thing is brand new and its acting up on me. Should I take it to my apple store? Should I just put up with it. I have tried everything and at this point I dont know what to do anymore. Please help!!
- Make an appointment at the Genius Bar of an Apple store.
Apple Retail Store - Genius Bar
Since you restored to factory settings/new iPod and still have the problem that indicates a hardware problem
If the iPod is defective within warranty (you indicate it is) and not abused Apple will exchange it on the spot. -
Sometimes when I open my MacBook Pro, it restores its RAM, as if it has run out of battery, even though it has not run out of battery and it has been charging. Why does this happen, and should it be happening?
It's similar to hybernation mode in Windows.
If you put your laptop to sleep, after X amount of hours it will move to the "deeper" sleep level (save memory to disk and shut down...), to save up battery.
Otherwise if you left your laptop asleep in the evening, you could wake up to a dead battery. Not a great surprise when you in hurry to leave the house with your laptop...

MacBook Pro doesn't hibernate when runs out of battery
Dear all,
I've been experiencyng this issue for quite a while now and is very frustrating. My MacBook Pro (Early 2011) doens't go to sleep as it should when runs out of battery. It simply dies. This is not a continuous issues as it happens 1/2 oh the times that battery runs out and I cannot connect it to power (low battery warning is also working perfectly).

Thank you in advance for your help!
Bests,
AlexHi all,
Thnk you for the reply.
@andyBall: I though that the battery might run out sooner than what it reports, however it typically behaves behaves quite well - 5+ hours after fully charged and approximately 10 minutes of operation after low battery warning. Very hard that battery is running out before the system realize that. Yet I have to try the SMC reset. Will revert.
@SilverSkyRat: I have one iCloud and one Gmail for work. Today I have disabled both and OS hibernated well (no failure). Later in the day I reactivated Gmail and system still hibernated fine. I mainly use the Mac for work therefore it's rather difficult to perform continus test of this kind. Although, system somtimes hibernates fine with also all account active.
General question, which are the program associated with "Address Book Source Sync"? Only "Contacts"?
Also, I have Little Snitch on the computer, may this be anyhow linked with this issue in your opinion/experience?
Best regards,
Alex -
My MacBook Pro is running very slow. How do I find out what is causing this?
How do I find out why my MacBook Pro is running so slow? Then how do I fix it?
Suggestions of Things You Can Do To Help A Slow Computer
If your computer seems to be running slower here are some things you can do:
Start with visits to: OS X Maintenance - MacAttorney;
The X Lab: The X-FAQs;
The Safe Mac » Mac Performance Guide;
The Safe Mac » The myth of the dirty Mac;
Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
used to manage backups and to restore backups. Time Machine
requires a backup drive that is at least twice the capacity of the
drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file. -
