  • My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

    My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

    If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

  • MacBook Air shuts down when I close it

    Whenever I close my MacBook, it shuts down instead of going into sleep mode. At first, I thought it was a problem with my MacBook not waking up from sleep at all, but if I use the Sleep function from the drop down menu, it will wake up normally.
    I've looked around the community to see if anyone had a similar issue, but most people say they need to reboot it to start it up again, which isn't my case at all. It just does a typical shut down. How do I make it go to sleep instead of shutting down when I close it?

    Triple-click anywhere in the line below to select it:
    bzgrep 'Previous Shutdown' /var/log/system.log*
    Copy the selected text to the Clipboard (command-C).
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V).

  • Macbook air shuts down when unplugged

    Hi,
    My macbook air is just 2 months old. Since yesterday my laptop shuts down when unplugged. And the time settings changes and I have to reset the time again everytime i switch it on. I tried reseting the system using time machine. Even that didnt work. Please tell me how to solve this.
    Thanks
    Shahzad

    Hi shafi.shahzad,
    I'm sorry to hear you are having issues with your new MacBook Air. Based on your description (issues with power management/charging, not retaining time settings, etc), you may want to try resetting your System Management Controller (SMC) and PRAM, as outlined in the following articles:
    Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
    OS X Yosemite: Reset your computer’s PRAM
    Regards,

  • My MacBook air shuts down when Apple logo appears

    Hey. My MacBook started to run slow and I forced a shut down and now when I try to start the mac, everytime it shuts down when the apple logo appears.
    What can I do and i also haven't backed up any of my files and I really need that stuff.

    If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

  • MacBook Pro shuts down when put into sleep mode

    Every time I put my Mac into sleep mode (plugged in or not, charged or not), it shuts itself down, and I have to restart it. I just got it (brand new) in August, so I know the battery shouldn't be bad.
    It's been doing this for about a week... I just changed to Snow Leopard yesterday, and downloaded the software updates and everything, but it still shuts down.
    Anyone know what I can do (short of sending it to Apple) to fix this?

    Okay, well I already used smartsleep.
    It fixed the problem I was having, but now my macbook started having the same issues again this weekend. It's happened twice tonight in the span of 3 hours.
    Do I need to uninstall SmartSleep then?
    And here is the report I get when the macbook reboots:

  • Macbook Air Shutting down when power is removed

    Helping my friend troubleshoot his Macbook Air, purchased summer 2014. He said it was a pain to get it to turn on, and I advised him against taking it to our university's help desk (If you can really call it even that).
    I have reset the NVRAM, PRAM, and SMC. I did an Apple Diagnostics Test three times, twice plugged in and once unplugged. Got ADP000 when plugged in and PPP007 when running on battery.
    When plugged in it does not shut down, however when unplugged it'll stay on 10-20 seconds before crashing. The first time I did the diagnostic test it shutdown before the test could be completed, the second time however was the longest it had stayed on before crashing maybe 30-40 seconds before I restarted to test while plugged in.
    I believe they only option left is to take it to an Apple Store, we are both from an area with an Apple store that is close however it is currently about 2-3 hours away from our campus.
    On a side note, I think there was some sort of malware/adware on it. The homepage in chrome and safari just didn't look right so I changed them to Google, and it got changed back to the odd looking one. The url said something like search.searchbenny - He also had kaspersky internet security installed, but it was expired or something. I don't think this could be causing the issue but I thought it was worth mentioning.

    If you click on the Apple menu's, "About This Mac," and then click on "System Report....," it will give a battery condition report. Best guess, as stated by Kappy, is that the battery needs to be replaced.
    If he bought in the summer of 2014, it should still be under warranty.

  • Macbook pro shuts down when put on sleep (OS 10.8.6)

    I have a Macbook pro (OS 10.8.6), when I put it to sleep by closing the lid or explicitly choosing sleep option,it goes to sleep, but when I open the lid, the machine shutsdown. I have to press the power button for around 30 seconds to start the machine. In the logs I could find--Shutdown due to error code --79 and sleep failure shutdown.

    Maybe some things to try check/try

    My macbook wont shut down when I close lid, how do I prevent this?
    This had happened before and I seem to recall having to disable blue tooth.
    Is this correct?

    It's not suppose to shut down when closing the lid, it's supposed to sleep.

  • MacBook Pro shuts down when i close the lid

    Hey,
    My MacBook Pro shuts down when i close the lid.
    It started to do this one or two times, but now it is every time.
    I have the latest battery update, so this should not be the issue here..
    Any sugestions??
    I have started to suspect the it might be some faulty conecctions or somthing..

    If it's unable to go into the proper sleep state for some reason then it will do that.
    Run /Utilities/Console and click 'All Messages' top left then close the lid, wait a minute then open it again - if it's shut down then reboot and open Console again and check the latest log lines looking for 'sleepimage' - it should give you an indication of what happened/didn't. If you're not sure what it all means post _just those lines_ here.

    Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
    Resetting the SMC on portables with a battery you should not remove on your own
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.

  • My MacBook Air shut down is slower than other macs I have seen

    I think this is due to the recent Mac OS 10.8.2 update
    My MacBook Air shuts down slower than usual. It will get slow and show a white screen with a spinining wheel taking up to 15 seconds.
    This is longer than the startup time.
    When it was new, I think it was running Mac OS 10.8.1. Shutdown was super speedy and took maybe just 3 seconds. It then asked me to update, so I obviously did, since I thought new improvments were made.
    So how can I get rid of this slow shut down timings?

    You might try resetting the SMC. If that does not work, take it in for service (you are under warranty).

  • 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.

  • 10.5.7 Shut down when put to sleep

    I updated my macbook pro sr to 10.5.7 today and noticed that when i close the lid, it shuts down after about 5 minutes. My battery is about brand new with under 60 cycles on it. I am wondering if anyone else can verify if this problem is only mine or something others are dealing with. I am sure that this started today after the update, as I had the computer asleep all day yesterday while at school. BTW, the mac is unplugged when it shuts downs. Thanks for any feedback.

    Here is a log of what happened last night. It shut down randomly today also but there was no error report that I could find. I deleted the plist file as suggested but have not yet restarted the system. I am trying it now. Hopefully you have some ideas from the log. If you need more info out of it, let me know. What I have gathered is firefox is what is crashing. Just updated that same day as 10.5.7 I believe. Will see if it still shuts down with firefox off. Thanks for your help again Yang.
