  • HT3964 My Macbook air charges intermittently. At times when I connect the power adapter it shows that power is coming in but  says "not charging" and the led light on the power adapter does not light. At other times it charges normally. Any ideas?

    Hey guys,
    I am having problems with charging my mac Air.  Sometimes it charges perfectly but then at times much as it shows that it's getting the power from the charger, it says "not charging" and the led light on the charger does not light up. Any help?

    That can happen when you are Taxing the system. No Apple supplied AC adapter supplies enough power to both power the system and charge the battery at the same time when the system is under Heavy Load, when you are Taxing the system heavily. At those times it will draw power from both the AC adapter and the battery at the same time. So if it is drawing power from both it can't charge the battery while it is drawing power from it.

    Take it back to the Apple Store for repair since it's still in warranty.

  • MPB Powers OFF when I connect the power cord

    Just got a new MBP this weekend. When I connect the power cord after the battery gets low, the computer instantly shuts off. No warning, just shuts off. The battery can be at any charge level, and this will happen. Pull the power cord off, no problem. Put it back on, the computer is off. I have to restart, unsaved changes lost. This is my second MBP, and the first one never did this. I am about to drag it in to the Genius bar, but has this happened to anyone else? Sounds like a bad hardware issue to me. Could it be a settings issue? I've only been using it for about three days. Thanks in advance.

    Welcome to Apple Discussions!
    You might try resetting the SMC and see if this helps.

    Hi robfromkinglake west,
    Try and isolate the issue.  Check if it's only with this drive.
    Check the drive with Disk Utility

  • When I connect my iPhone 4S to my MacBook Pro, the synchronization process by iTunes failed with the following message "My iPhone could not be synchronized, because the synchronization process has not started". What does that mean?

    Hello,
    When I connect my iPhone 4S to my MacBook Pro (through the USB port), the synchronization process by iTunes failed with the following message "My iPhone could not be synchronized, because the synchronization process has not started".
    What does that mean?
    Thanks in advance for fixing my problem.

    I think I remember hearing that if you quit iTunes with your device still connected, then open iTunes up again, it should work.
    EDIT: Here, this might help: http://support.apple.com/kb/ts1567

  • How do I fix the power button on my MacBook Pro?

    How do I fix the power button on my MacBook Pro? Thanks to Apple,  if you accidentally hit the power button with Mavericks, your downloading, ripping, burning, saving and any other process will be halted without completing.  How do I fix this so this no longer happens?

    Which os version are you using?  Which model Macbook Pro do you have?
    Does this article apply - MacBook Pro: Distorted video or no video issues?  The affected computers  were manufactured between approximately May 2007 and September 2008.

  • Is it possible to change the hard drive in a macbook pro, if so where from? and how?

    is it possible to change the hard drive in a macbook pro, if so where from? and how?

    whats a green drive? thnks
    Green is a marketing term for a drive designed for lower power use, lower noise, and lower heat. The side effect is that it's not as fast. Black drives are designed for highest performance, so they might use more power and run hotter and noisier. I upgraded my Apple Time Capsule with a green drive, but I put a black drive in my Mac Pro.

    7200 RPM drives are faster than 5400 RPM drives.
    As in cars, RPM is not the sole determinant of performance. In some cases, a newer drive at a lower RPM is faster than an older drive at a higher RPM, when the newer drive uses better technology. I have heard that some of today's high-capacity 5400RPM drives are faster than 7200RPM drives of lower capacity simply because the very high density of a 1TB drive means more data passes under the head even at a lower RPM. Certainly there have been times in Apple's past when new lower RPM drives were faster than higher RPM drives of the previous generation, a notable example being when 4200RPM perpendicular recording drives were introduced and beat 5400RPM drives.
    Yes, generally RPM can be used to compare, but it is important to realize it isn't always true.

  • My Macbook Pro goes to sleep when I connect the magsafe adapter.

    Hi, if I am using my MBP on battery and then 1) close the lid to put it to sleep, 2) later connect it to the magsafe and then 3) try to wake it up (in that order only, and more frequently if in the login screen), it powers up for a second then goes back to sleep. Not always but frequently. It takes about 10 seconds to power down, and then once asleep, it takes about 5 seconds before it will wake up again. After that, everything is fine. My only workaround seems to be to wake the computer first, wait about 10 seconds and then connect the magsafe. Has anyone else experienced this? I never noticed this before I upgraded to Mountain Lion.

    This very well could be the same issue as below.  Please read the full copy of the post and see if the behavior matches.  What's happeing is that if you have this update installed, whenever you plug or unplug the power adapter to the laptop, the system will wake from sleep and then go back to sleep if the lid is closed.  What you're doing is plugging it in which causes it to wake up, then when you finally open it a couple of seconds later, you're catching it as it's going back to sleep and once it does that it then sees that you opened it and wakes back up again.  Either plug it in and wait for that wake/sleep and then open it or open it and then plug it in.
    Post about the problem in detail:
    This is a problem with all 2012 MacBook Pros that have applied the update DL1609 via Software Update.  This update is called MacBook Air and MacBook Pro Update 2.0.  The only fix that exists for this is to reinstall OSX and just not install this update when it shows in the available updates list in the AppStore.  Just hide it until this issue is fixed by Apple.
    If your OSX 10.8.2 version is anything after version (12C60) then you will have this problem.  The problem is as follows.  With the system asleep with clamshell closed, plugging and unplugging the power cable causes the system to wake up and go back to sleep.  Additionally, leaving the system plugged into power for over 4 hours will cause the system to go into hibernation, but only when plugged in.  If it's not connected to AC power while sleeping for that long, it will not enter hibernation.
    Please call Apple and complain about this problem.  I have been working with them for over a month and a half trying to get them to fix this and it's a major hand-holding process because they didn't initially understand the issue.  Add to that the fact that they insisted that this problem doesn't exist and it just made it that much harder to get them to see the issue.
    You need to call them AppleCare and let them know you're having this problem.  Along with that, email the rep you're working with links to every Apple Support Forum thread you can find on this.  Trust me, there are several with this same exact problem.

  • Powerbook turns off when I unplugged the Power Adapter

    I month or so ago I noticed that when I unplug my power adapter it turns off instead of running off the battery. I've tried resetting the PMU but I didn't work. Does anyone have any advice or does anyone know what could be the problem.

    I am experiencing a similar problem to Blaise. I have owned my 15-inch Dual-Layer SuperDrive for a total of 4 days. Last night I went to move my computer from the living room (where it was plugged into the wall for approx. 5hrs) to my bedroom. So I simply pulled out the power cable and the screen went blank. At first I thought it went to sleep (which was weird even if that was true), but then I tried to wake it up. Nothing worked. So I moved it into the bedroom, plugged it in, then I basically had to power it up as if it was off. Although, since it is the new PowerBook it was still able to write the contents of RAM to the hard drive (which is a really cool new feature). So the dimmed screen had the progress bar on the bottom as the previous settings were loaded.
    Anyway, my long story aside. The battery level monitor in the menu bar, now says 0%, when I unplugged it, it said 99%. The green indicators on the battery itself all light up as if it is fully charged. I also looked in system profiler, where it says the capacity is 0mAh and the total charge is 0mAh. Then I ran apple hardware test, where it told me that no battery was present but it was still able to say it experienced "10 cycles".
    I have tried to reset the PMU and the PRAM, no help. I've restarted to see if it would luckily rerecognize it. But nothing has worked.
    I will be venturing to the Apple Store this afternoon. I hope it is an easy fix, i.e. just a new battery. Basically the current condition of my computer, is that I need to be plugged in to use it at all.
    It must be reiterated that this is a brand new machine. And the battery capacity just hours before this incident was 3639mAh (I've been checking it periodically since I got the machine to see how the battery was doing on the first couple of cycles). And it had only experienced 10 charge-drain cycles.
    If anyone has any ideas to fix this, I would greatly appreciate the help.

  • Macbook powers on by itself when i connect the power cable

    Hi,
    Since Leopard, my Macbook has decided to no longer rely on the stupid user pushing the power button. It simply switches itself on every time i connect the power cable
    You know: I often come home in the evenings with a drained battery, connect the cable and charge the battery overnight. I don't want to switch the baby on. But my Macbook thinks otherwise.
    First i thought it maybe have somthing to do with the hardware-energy settings (power on after power loss), but the option is disabled.
    So what? Has the Macbook become more intelligent or am I just to stupid to find the right option? (Care what you say..!)
    Cheers,
    Fox

    Hello World!
    No one here who can help me?
    I simply want to use the Power Button for what it is for. I don't want my Macbook to switch itself on everytime i plug in the power cable.
    This behaviour is only since 10.5 install (I did archive&install)

  • TS3622 It even happens when you connect BOTH power cables on a Mac Pro 3,1

    I  have a Mac 3,1 and have recently fitted the ATI Radon HD 5870 replacing the old graphics card. (It is one week old)
    One monitor is the NEC Spectraview 2690 which is connected to the mini-Display port and the other monitor is the Apple 23" connected to the DVI port.
    After I have shut down the Mac Pro at night and restart it the following morning,  two (BOTH) blank screens appears on booting up.
    I then have to press and hold the power button to shut down the system and then reboot the sytem and then the screens come up properly for me to log in.
    I can then use the computer as normal.

    There is no BIOS in OS X. There is only the EFI stored in ROM that is not user modifiable. OS X is probably checking Bay 0 for the boot drive since that is where it should be. It won't check the Tempo drive since it is treated like an external drive. I suggest you open Startup Disk preferences to see if the Tempo device is selected as the boot device. If it isn't, then select it. That will probably shave off a few seconds in the startup time.

  • Can I use adapter of the iphone (not the cable), to attach the power cable of a macbook pro bought in Canada? The power adpter for the macbook pro is two pins because it was bought in Canada. Thank you.

             Hi! I will get a macbook pro bought in Canada soon. Can I use the adapter plug of my iphone (ireland) not the cable, as the adapter to plug my macbook? The power adpter of the macbook from Canada is a two pin. Thanks for any help.

    I wouldn't, the Mac draws significantly more power than the iPhone. Why risk it.
