My MacBook pro 2011 isn't charging!
My 13" MacBook Pro 2011 i7 model isn't charging. It's only 2 weeks old. The magsafe adaptor light doesn't come on at all, I have tried restarting my computer, and I have tried several different power outlets, all give the same effect. I havn't been rough with it, the most travelling it has done is going between my bedroom and my loungeroom. The screen seems to keep dimming and lighting up, but I may just be seeing things being paranoid.
What can I do? Will Apple cover this in the warranty if it's actually broken? D:
Try this first:
Intel-based Macs: Resetting the System Management Controller (SMC)
If that doesn't help, it's a warranty issue.

Late Macbook Pro 2011 won't charge via MagSafe adapter.
My friends Macbook Pro 2011 same as mine wont charge the battery via MagSafe adapter. The battery is good and the adapter also, ive checked them on my Mac. The problem is that on her Mac it won't charge. I've change the MagSafe adapter on her computer and it didn't work still no charge, no green light on the L shaped adapter. Can it be the Logic Board?
Resetting SMC could solve the problem.

MacBook Pro (2011) Won't Charge Without Restart
Hi guys, I searched the forums for this problem but couldn't find a match. When I plug the power cable into my 2011 17" MacBook Pro it won't take a charge and the light on the cable doesn't come on. However if I restart the computer, the light will come on and it will start charging. This sounds like a software issue to me and I haven't had the problem until recently so I'm guessing it's caused by the latest OS X update. Has anyone else experienced a similar issue and found a fix?

The battery doesn't charge at all anymore.
My Macbook pro suddenly stopped working without the cord plugged in.
And when the laptop is switched off, it switches on by its own as soon as I plug it in.
I reset the SMC, to no avail.
Any tips?
Thanks.
MacBook Pro (13-inch Early 2011), Mac OS X (10.6.8), 2.3GHz Intel Core i5 processerIf it has a replaceable battery, then consider replacing it.
Open System Profiler in Utilities folder. After it opens click on the Power entry in the sidebar. See what it reports for your battery. If it's no longer usable it will generally say "Service."
If you don't have a user-replaceable battery, then take it to an Apple Store. -

Macbook Pro 2011 battery not charging error code
My Macbook Pro just turned 1 year old and the battery might be defective or dead ( Warranty just passed by ) it originally cam with Snow Leopard but I WEB upgraded to Lion (which was far from being easy ... had alot of crashes and hanging happening)
I have the now infamous battery not charging problem. The OSX status bar shows the battery icon with a 'X' meaning no battery. I think the MacBook is not charging the battery because OSX doesn't see a battery.
Today I just noticed that (IMPORTANT) with the power adapter connected, pressing the battery power level button displays a 5 blinks code. Otherwise with power adaptor not connected, the battery seems even too weak to light up even a single LED".
Even though I do a proper shutdown, it is to note that the MacBook Pro starts right away when I plug the power adaptor. I starts right away without me even pressing the power button.
Yerterday I really though the MacBook Pro was not going to work anymore, it kept abruptly shuting down again and again. I couldn't do any of the work I was supposed to.
I did PRAM and SMC resets and eventually I was able to startup the MacBook Pro and do some work but the battery still remains unavailable.
I have 2 of the same 85 Watt charger ( the first one being from a previous MacBook Pro 2008 --- which is waiting to get a repair ) and both performs the same: not charging.
Maybe the battery discharged beyond the point it can be seen my the MacBook Pro and OSX. Just like car battery, if it get discharges way too much, you won't even see the nominal voltage on the terminals even without any load.
EDIT: just noticed that even though it looks like no battery OSX reports that power source IS BATTERY (in the OSX status top bar )It's like mpg for a car. It depends upon how you drive, the weather, the terrain. "7 hours" doesn't mean anything. Your mileage will vary. If I am not doing anything I see 13 hours. As soon as I start surfing or watching a video it changes. Stop obsessing.

MacBook Pro 2011 Battery Re-Charging Issue
Hey everyone, I discovered a problem on my 2011 MBP 17" which I was told that "it's perfectly normal' and I want to see if you guys can reproduce it on your new 2011 models as well (please indicate your screen size).
In summary, I noticed that depending on CPU usage, the battery reacharge time will greatly fluctuate to the point where the laptop just stops charging the battery. I noticed the giant fluctuations in time when I booted one of my VMs which used up like 15-20% overall cpu usage. I was at 5% battery life and the computer was plugged in recharging and the battery indicator all of the sudden went from somewhere around 2.5 hours recharge time to 10 hours to 15 then 20 hours. Then at some point the magsafe light went green and the battery indicator showed 'Not Charging'.
I thought that I may have a bad MagSafe so I tried the one from my 2009 MBP (both are the 85W version) and bam same problem. I figured that this may be due to a design flaw where the power unit cannot supply enough tower to feed a CPU that's being somewhat taxed (i'm talking about 25-50% usuage) and recharge a battery.
Here is a simple way to try to reproduce the problem:
1. Let you battery drain to about 80% or less.
2. Close all open programs.
3. Change your battery indicator icon in the menu bar to display the info as 'Time'.
4. Plug in your MagSafe and let the recharge time in the battery indicator calculate and stabilize (give it about 2 mins to get a stable time value).
5. Open up safari and go to Hulu and play any TV show to drive up your cpu usage.
6. Then open Terminal and type the command 'yes' (without the quotes) and hit enter. The 'yes' command basically causes an infinite loop of the letter 'y' to be display in the terminal window which also taxes your CPU in addition to the video playing in Hulu.
7. Now watch the battery indicator's recharge time value and you should notice that it'll start going up significantly in time and at some point it'll say 'Recalculating' and eventually it'll give up and say 'Not Charging'. I have a 2009 MBP 17" C2D 2.66GHz, and although the recharge time goes up by 20-30% in the exact same test, it at least still charges the battery.
I was able to reproduce this at the apple store on a 17" 2011 model as well but I'm curious if this also happens on the 15 and 13 inch models. I was told by the engineering team on the phone that this is 'perfectly normal'. I guess it falls in the category of malfunctions as designed...
null
nullTheRosta, jkirker and zapatillo: Everything you report is normal. Under heavy load, more power is delivered to the CPU/GPU/other hardware and less to the battery charging circuitry. Under very heavy load, all power goes to the processors and none to the battery, and under extreme loads, power is drawn from the battery to supplement what is provided by the AC adapter. All of this is by design.
You might well ask why Apple didn't just provide a more powerful AC adapter. I don't know Apple's reason(s), of course, but one possible explanation is that the machine couldn't dissipate the additional heat that would be generated by feeding 20, 30 or 50 more watts into it. If that's the case, then maybe the present 85W adapter is the best compromise Apple could devise between providing sufficient power and managing heat effectively, without completely redesigning and enlarging the MBP case to accommodate bigger fans and heat sinks and more air circulation space. -
US macbook pro - converter isn't charging macbook pro
Hi
I realise people might say 'I told you so!!' and rightly so... I recently purchased a mbp from the states - got a us to uk plug converter but it still isn't working... any suggestions?
Thx
AshYou just need a figure of 8 ac cable - (figure of 8 is the bit that plugs into the white adapter) or a plug converter which converts the 3 pin US cable to a 3 pin UK cable.
The ac adapter is autoswitching 110-240v so you don't need anything that does any sort of conversion - you just need to be able to plug it into a UK socket. If you can get an ac cable from something like a video recorder you might be able to try that. There are basically 2 types of ac cables in the UK - Kettle leads - have a larger plug and a "figure of 8" cable which is smaller and looks like an 8 unsurprisingly.
Also - If you already have it plugged in and are not trying to convert voltage, see if you can run the machine off ac - it may be that there is something up with the battery. If it runs, try running on ac without the battery for a minute to confirm.
Hope that helps. Best of luck. Absolutely no reason it shouldn't work. -
So a few weeks ago my MacBook Pro 2011 started having charging problems. I would use it normally. Then plug it in to charge anywhere between 5-20 percent like I've been doing for the past year that I've had it (since August 2011). Anyway, what happens now is that it charges but extremely slowly - at least 4 hours to fully charge as opposed to the 1 1/2 to 2 hours that it used to take. Also, it seems to be draining a lot quicker than it used to while only browsing the internet. Furthermore, while charging, the battery meter goes from the percent its charged to to "not charging" back and forth. What's going on? Is there a problem with my battery, my computer, or the magsafe charger? [please refer to the pictures below to get a better understanding of my problem - these pictures were taken over a 2 hour time period - a time period that usually is enough to charge my computer] - if you'll notice, in the first two pictures, the percent barely went up by 10 in a half hour period:

Unusual shutoff on Macbook Pro 2011 while sleeping
My 13" Macbook Pro 2011 will be fully charged and will go to sleep normally. However, I will go about my day and 4 hours later I won't be able to turn my computer on unless I have it connected to the power adapter. Then when I turn on my computer, the battery life percentage is 0%. Why is this?
Isn't the battery supposed to last at least a day or so while in sleep mode?Your hard drive will last a while longer if you keep the moving to the minimum when it is on, but on short term there aren't any problems. I have never even tried not to move my MacBook when the drive's spinning, and it still works fine after 2 years.
Of course, if you would have an SSD, move the thing as much as you want. Since they don't move on themselves, they can be moved freely. -
Macbook Pro 2011 running very slowly after upgrading to Mavericks
I am in deep trouble with my wife so any help would be gratefully accepted.
Shortly after Mavericks became available I upgraded my wife's Macbook Pro 2011 to use the new OS version. Ever since then, the Macbook has been running noticeably slowly. In particular, Mail is almost unusuable taking minutes to open and showing long delays while moving around messages, folders, etc. Excel and Word are also much slower, Safari is slow, in fact just about everything is grinding.
Any ideas on what can I can do to improve things and apease my unhappy wife would be much appreciated.
I have attached the Etrecheck output FYI
Thanks

Macbook Pro 2011 - Apple It's time
Hi,
So I'm the owner of a new second-hand 17" Macbook, for years I've dreamed of getting one of these and today was finally the day it happened. Specs are
Macbook Pro 2011 Late
i7 2.4Ghz
6770m
8gb RAM
At first the laptop booted up fine so I decided to do what any new proud macbook owner would do, show it of at work. During the course of the day I experienced intermittent freezing issues and eventually a blue screen of death. I thought to myself that I must of brought a dud and immediately went to contact the person I brought it of for a refund. Being a genuine trader he was more than happy to oblige and give me a full refund. Frustratingly this macbook had already grown on me enough to the point where I was determined to research into solution. Initially I suspected a HDD fault so I went to attempt a apple internet recovery, all that solved was my blue screen of death and changed it to a grey screen of death. Digging deeper it was clear from countless others in my situation that the issue was being caused by the GPU.
Now I'm no apple genius but I have enough of a computer technical background to know when something has not been done right. Now clearly apple has done wrong in the manufacturing process of GPU soldering and thermal paste application. This issue is nowhere relevant to software except for the point in which the system switches from the integrated to the faulty discrete GPU like it's suppose to in high-intensive tasks. Having this macbook for only a day and some determined researching its pretty simple to join the dots. The soldering process and material they used was doomed to fail from the start, eventually all 2011 models with discrete GPU's will burn out, it just depends on how well their owners have taken care of them. In regards to the thermal paste application you will be able to see from my images the kind of care and pride apples has undertaken in applying it. There was more around the CPU & GPU than there was on itself, that's like having a peanut butter and jelly sandwich with most of the peanut butter and jelly smeared around the plate. Considering this laptop would of cost close to 4500NZ back in the day I can't imagine what other original 2011 Macbook owners are feeling.
What makes it worse is that apple techies you go to will say a full logic board replacement will be needed from your own pocket when your macbook was already doomed, isn't that a way to rub further salt into the wounds Apple. Opening up my macbook it was obvious to see that the logic board inside was not the original and sometime during it's lifetime it too had a full logic board replacement. However I can't say if it was for the same reasons. Regardless it's obvious that replacing the logic board does not solve the issue and wastes everybody's time and money.
Apple, these macs require two things.
-A solder repair for the GPU
-A re-application of thermal paste
It's really not that much to ask considering the worth of these laptops, also wouldn't you rather have these leaving a legacy of the ultimate desktop replacement than apples shameful ticking time bomb?
I'm typing this of the very macbook having these issues so for anyone who wants a temporary fix please refer to the free gfxCardStatus software which allows you to force integrated graphics only. For now it's stable but dreadfully hinders the potential this beast was made for.
"Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations."
"Quality is more important than quantity. One home run is much better than two doubles."

In hopes that apple does not remove this post.There is excessive swapping of data between physical memory and virtual memory.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. 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 process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
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. -

Step 4: Install the Boot Camp Drivers for Windows
After installing Windows, install Mac-specific drivers and other software for Windows using your Mac OS X installation disc. The Mac OS X disc installs drivers to support Mac components, including AirPort,built-in iSight camera, the Apple Remote, the trackpad on a portable Mac, and thefunction keys on an Apple keyboard.
The Mac OS X disc also installs the Boot Camp control panel for Windows and theApple Boot Camp system tray item.
To install the Boot Camp drivers:
1 Eject the Windows installation disc.
2 Insert the Mac OS X disc. If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
3 Follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.
Windows that appear only briefly during the installation don’t require your input.
If nothing appears to be happening, there may be a hidden window that you mustrespond to. Check the taskbar and look behind open windows.
Important: Do not click the Cancel button in any of the installer dialogs.
4 After your computer restarts, follow the instructions in the Found New Hardware Wizard to update your software drivers (Windows XP only).
5 Follow the instructions for any other wizards that appear.
6 Check for updated Boot Camp drivers by using Apple Software Update or going to www.apple.com/support/bootcamp.
If You Have Problems Installing the Device Drivers
If it appears that the Boot Camp drivers weren’t successfully installed, try repairing them.
To repair Boot Camp drivers:
1 Start up your computer in Windows.
2 Insert your Mac OS X installation disc.
3 If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
4 Click Repair and follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.
If you need to reinstall specific drivers, you can install one driver at a time. For example,if your built-in iSight camera isn’t working, you can reinstall just the iSight driver.
Individual drivers are in the Drivers folder on the Mac OS X installation disc. -
Hi there. I have a brand new MacBook Pro 2011 and I'm having some problems with my wireless connection. I have in the same room a Mac Mini, my Ipad , my Ipod, 3 PC's and all of them have a wireless connection. I notice that since my last MacOSX update I have some problems with my wireless connectivity in my Macmini. Now I'm having the same problem in my macbook pro. I have internet in all my other devices but no internet in my Mac Mini or Macbook. The Access point is 5 meters away from my devices. I put some repeater in the middle to repeat the signal but I'm getting the same beavior. Can someone help me on this? If I go to the network setting and renew my DHCP address I can access the internet but after 15 minutes I'm getting the same problem again.
The signal bar on the menubar is not always an accurate indicator of how strong the signal is. A more accurate measure is if the signal drops entirely and you are definitely in range of the airport base station. Also anywhere within 3 meters you may get signal degradation because of overlapping radio waves cancelling each other out. You also have the option to ask to speak to a customer relations person when you call AppleCare, and ask for an expedited repair, and have your airport card properly seated. Sometimes they can get loose, or the antenna can get loose inside, though normally this isn't a problem unless the machine has to be opened for some reason.
