My MacBook Pro has charging problems, when I connect the mag to the plug the led lightsand starts to charge the Mac but after approx 20 seconds it turns off and stops charging the Mac so it is impossible to turn the computer on. any explanation?
I need some help when I connect the MagSafe to the Mac and to the plug the led of the MagSafe lits green then it turns yellow charges the computer for about 20 seconds and then it turns off. If I disconnect the MagSafe from the power sock and I connect it again it restarts the same procedure charges the computer for a few second and turns off again. Does anyone know the solution to this problem?

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. -
I received a 2012 MacBook Pro INtel i7 for my birthday this May 2013. It constantly drops my airport connection. My ancient 2006 MacBook Pro has no problem connecting to airport, nor staying connected. I've had to write this message several times as I keep losing the airport connection and have to reconnect. BTW: I am less than five feet from the airport base.
Thanks for help.After trying all of the above the suggestions, the problem returned as before. However, after digging some more I discovered that the issue appears to lie with the 10.4.10 version of the Mac OS; when I checked the software log under the system profiler I noticed that I had installed that update at about the time my Airport problems began. Apple then quietly released a v 1.1 combo update to 10.4.10 on July 2nd, which once installed appears to have resolved the problem. You can find the download at http://www.apple.com/support/downloads/macosx10410comboupdatev11intel.html
What's curious is that originally Apple listed that the v 1.1 combo update resolved some issues with RAW image data, and some sound problems, which don't seem to have anything to do with Airport. -
So in the last few days I’ve noticed that pressing my volume change keys actually isn’t changing the volume on my macbook pro at all. When I press the volume up or down keys, it makes the recognisable pop sound but stays at the same volume while the squares go up or down. I mute it but my computer still makes sound. It’s the same with the volume control up the top of the screen, too. I slide it up and down and it doesn’t change the volume at all. The only way I can change the volume is with my speakers or the program I’m in (iTunes, VLC etc). I restarted and it seems to be okay then I go to change it a couple minutes later and it’s back to not working again.
I’ve checked my settings- the “use all F1, F2, etc. keys as standard fuction keys” is not switched on, and I have tried a suggestion of moving the com.apple.systempreferences.plist file out of the library and onto the desktop and restarting and neither of those seem to make any difference whatsoever. I’ve tried to find online forums but the only suggestions I found were those two and they didn’t work.
I’m just annoyed because I usually have the worst luck with technology but my macbook had been going strong and I got it because of the apparent lack of things that could go wrong, but of course even if there is one thing that could go wrong it will happen to me.
Please help!You migh give resetting your NVRAM a try:

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi
What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi
Hello Alex,
It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Cheers,

I downloaded Piezo to my iMac about a month ago. Now I can't download it to my laptop even though I have authorized the MacBook Pro in iTunes. When I open the App Store, the Piezo app indicates that I have to pay. How do I download Piezo to my laptop, which I am entitled to do?
I'm running Snow Leopard on my iMac. I have a heap of documents that were created using an old word processor application called Apple Works and it wont work on Lion or Mt Lion. So I'm stuck with Snow leopard for the moment. I guess I can't use the new iPhoto either then...

A clean install on my MacBook Pro has left me with my icons stuck in the grid on the right side of my desktop. I had the ability to move them and have them stay put in various sectors of the desktop, which I found very useful. The clean install upgraded the OS to 10.6.8 from 10.5.8. I want to move them again but there I see no 'None' option which I think would free them to move where I wish. Has the upgrade deleted that option? Suggestions? I am new to this community and if not new to Mac, I often feel that way. This is one of those times.
Julz11 in NYCI have the same problem on the latest iTunes software and Windows 7. My window is maximzed and I do not see any tab for photos. Seems related to a recent update (IOS7?) as this was there - at least before the very big change to the interface.

Why won't my MacBook Pro go to sleep when I close the lid?
All of a sudden, my MacBook Pro has stopped going to sleep when I close the lid. Instead, the indicator light on the front stays on steadily. When I then open the lid, I am asked to log in again, but before I can type anything, the window goes completely black. My only choice at this point has been to hold the power button down long enough to shut the laptop off. Then I wait a minute or so before restarting. Is there a setting I need to check to prevent all of this from happening? I have tried restarting in Safe Mode, then restarting normally, but still the laptop will not go to sleep when I close the lid.
Some process is impeding the sleep function. Since you've tried rebooting and it persists, check and see if Time Machine is hellbent on completing a backup, cause it can have that effect.

Hello all,
I am new to posting on this forum but I really hope that someone out there can help me out. I have a 13" MacBook Pro, 2.53 GHz Core 2 Duo, 4GB 1067 MHz DDR3, running OSX 10.6.8. My problem is that when I unplug the laptop form the charger and run it on the battery, the computer becomes unresponsive to any commands at all. It basically really slows down to a crawl. Even when rebooting it will take 5-10 minutes or more to do so. The odd thing is, when it gets plugged back in while any of this is going on, within a minute or two it works perfectly. It has been in a mac authorized repair shop for 7 weeks and has had a new logic board and a new hard drive replaced. The battery was tested and charges fine, holds a charge when unplugged, and the system profile shows the battery at Normal. Recently, many knowledgeable mac enthusiasts gave me tip that might help. Here is what I did: Ran an SMC reboot (no success), rebooted the computer under safe mode then unplugged it to test (no success), and ran a hardware test on the install disk (showed hardware ok)
I am at a loss as to what to do next. It has become impossible to use this laptop for my classes when it is unplugged. I am about ready to just go buy a new one, and call this one a goner.
I am hoping someone reading this can help with any other ideas on its problem. Help? Anyone?
SteveLPBassman,
since the tech in your IT department was able to copy your daughter’s data from her MacBook Pro’s internal disk, I’d suggest completely erasing the internal disk (using Disk Utility in Recovery mode, reformatting it with a “Mac OS Extended (Journaled)” filesystem), reïnstalling its original version of Mac OS X (either Snow Leopard from the grey Mac OS X Install DVD if it originally came with two grey DVDs, or Lion via OS X Internet Recovery if no grey DVDs originally came with it), running Software Update to get it to 10.6.8 or 10.7.5 respectively, reïnstalling Mavericks, running Software Update again to get it up to date, and finally restoring your daughter’s data. -
My new MacBook Pro has display problems
I am new to Mac. I had purchased a brand new MacBook Pro 13 inches with i7 processor on April2 this year, Within 10 days the display screen started to grey out and later on develop horizontal lines. I telephoned Apple support and when a telephonic solution became unlikely I was asked to take it to an Apple Authorized service centre in my town. The technician there could not clearly explain to me what was wrong with the system, but I understood him to say that he has reinstalled the graphics driver and the system was trouble free for a prolonged time thereafter (at the service centre). I also understood him to say that should the problem recur again, he would have to replace the motherboard. I was on a travelling tour for a week after this and was not able to test out this repair (I took my old windows system with me for the travel) To my utter dismay the problem has recurred again after 28 days of purchase. I have attached screenshots. The button for uploaing videos is greyed out therefore I will have to restrict myself to screenshots. All the three screen images occcur
in turn and the system becomes unusable and I have to use the poweroff button. The display problems start within 10 minutes of switiching on the system.
I took some time to discover these forums. The first time this problem occurred on my machin I posted this problem on mac-forums and I was advised to take it to an Apple store and let the apple genius bar worry about this one. I do not live wihtin any sort of manageable distance from such a place and the repair centre is an Apple Authorized Service Provider
Coming to the emotional aspects of this technological glitch. I feel like I have been hit by a truck.I had saved and scraped pennies to buy this dream machine and I believed I was escaping the ficleness of windows. But no windows system of mine (I have three) become so unusable
Will I have to spend time and effort to lug this machine to service centre to replace each of its component parts one by one ? Can I ever trust this machine to provide a presentation to an audience? What sort of an impression will I create if the system plays this trick on me in the middle of some presentation?Shootis007, What is CC company? I googled CC and got many different answers.
I called Apple Support and told them my story and pressed for replacement and they told me repeatedly that there is no policy for replacement. The initial support person who attended my call asked me to take it to the seller and ask the seller for replacement. I dont think that is the way to go. I dont know what is his fault. He gave me a brand new system, the package was opened by me. Since I am new to Mac, I had taken a Mac user friend with me who showed me how to get started (right there in the shop) Neither the experienced Mac user friend nor I felt anything remiss at that time or later at the Seller level. Nevertheless I called the reseller and he explained his helplessness. I dont think it his fault at all.
Since I kept insisting on replacment I was put through to another support person who took pains to reassure me that I should get the defective part replaced and thereafter all will be well. For now I trust him. I have no other alternative
I really am puzzled. All you dear Mac users should know that the machine I dreamed of and really saved to purchase is giving me no end of troubles whereas my three windows machines sit there with their numerous stated deficiencies but gives me uninterrupted service -

My MacBook Pro has booting Problems, Light keeps on Blinking. What to do?
My MACBOOK PRO (Early 2011) is having booting problems. It doesnt want to be shut off. If I do shut it off it would take an hour for it to boot. The light keeps on blinking when i push the on button. After a few times of pushing the button and the blinking light the light keeps steady and the MACBOOK PRO seems to be turning on . A Whirring noise/ sound can be heard. I then turn it off and push the ON Button again and the MACBOOK PRO finally boots. The problem repeats again when i turn the unit off.
I already had it checked by APPLE but they said they cannot find anything wrong with it!! Any help will be highly appreciated.Shut the machine down by holding the power button until the computer is off.
Release the power button.
Reset the parameter RAM by powering up the machine then holding the key combination:
<COMMAND> + <OPTION> + p + r until you hear the restart chime three times
Then perform a SMC Reset by following this procedure from Apple:
