Macbook Pro alternates between charging and not charging
Hello,
I have a 15-inch Late 2011 MBP, and the problem that I am currently having, is when I am charging my MBP from a relativly low charge, or when I am charging it as well as running a highly demanding program, the power adapter will get extremely hot to the tuch, and my computer will then alternate between charing and not chargin. When the computer is aternating between charging and not chargin, the light on the Magsafe connector will be orange (like a normal charge), then it will go out (like I unplugged the addapter from the wall), then it will turn green (like when it is fully charged/or when you first connect it to the computer before it startes chargeing), then it will go back to Orange for a few (~10-15 seconds), then it will start the cycle all over again.
Some side information that might help: This is my second charger for this computer, the cord right behind the Magsafe conector fell apart after a few months; I did however replace if with an Apple 85W power adapter (no offbrand/knockoff). Also, the grounding plug on the extension broke off a while ago, however I did use this same extension (the original that came with my computer) with the original addapter which I had absolutly no problems with (appart from falling appart after a few months).
I am considering getting a new Extension for my computer, because i beleace that the fact that there is no ground is causing static/buzzing when i use headphones, though I bleave this is not realted to my power adapter problem.
So, do you think I should just replace the entire addapter and extension? I wanted to ask here first, because I do not want to get a new addapter if it is going to do the same thing again.
Thanks for any addvice!
First, if your computer is under Applecare, so is your charger. If it is, just take the charger and computer to the Genius Bar and they'll take care of it. If it's not, you still might want to make the trip to the Genius Bar. The eval is free, and you'll find out exactly what your problem is. Not to mention that you're in the right place to buy another one if you need to.

How can i get my macbook pro too stay on and not sleep when lid is closed?
how can i get my macbook pro too stay on and not sleep when lid is closed?
If the machine is asleep, lid closed, and you plug in to an external monitor and an external USB keyboard, the machine will wake, anbd reconfigure the screen resolution for the external monitor, Once it has made this configuration change, you can open the lid and it will continue to address only the external monitor. At least that's how my early MacBook Pro unibody 13" works. It seems to run a bit cooler this way. It gets quite toasty with the lid closed while doing anything demanding and you are more likely to hear the fan come on. I have not seen any temps that would cause alarm, but I do get a high speed (6000 rpm), noisy fan sometimes with the lid closed, .
If you operate in the open-lid, external monitor only mode, if you deactivate the monitor for any reason, when it reactivates it will be running both screens, with all the navigation hassles this entails, so I generally set it not to deactivate the screen when in this mode.
Thus I agree with those who say that some of the cooling air is drawn in around the keyboard, the difference in cooling performance is observable. If you activate istat pro, get the computer hot running in clamshell mode, and open the lid, you can watch the CPU temp drop by a few degrees C within a couple minutes. It isn't a huge difference, but enough the lower the fan speeds. -

Why is my Macbook pro now extremely slow and not running things like powerpoint any more?
I'm sure I'm not the only one.
Mavericks installed. Now my Macbook Pro is slower than a one-legged tortoise.
It won't run powerpoint, which just crashes. en my keyboard misses the first part of sentences because it can't keep up. I have to double check everything I type. I'm trying to run a business, and I'm losing time, money and the will to live.
I cannot reinstall microsoft office, as I bought my macbook Pro (2 GHz Intel Core i7, 8GB 1600 MHz DDR3) from a seller who cleanly installed Mountain lion for me, and installed Office 11 on it. I do not have any installation disks. I have been forced to downgrade to Mountain Lion, which I'm still waiting for Apple to send to me.
Is there anyone out there who can give me any help. I'm not paying Apple any more money. Why should I? I've already been forced to rebuy an operating system that my Macbook previously had installed.
Not only that, I think I have an expanding battery issue, and my trackpad is now broken. Just to add to my woes.
Has anyone had a solution to solving the Mavericks debacle?
Please somebody, help.
Please.
Before I start self harming.Hi all;
I agree with stobston, many thanks to cbs20 for your inputs. I was stuck with this one also. I'm a former UNIX sysadmin; thanks so much for pointer to etrecheck. It's nice to be able to look under the hood.
I had the same problem, Powerpoint was so slow as to be nearly useless. Apparently different cause&effect from stobston's case. Here's what worked for me. Sorry if I'm stating the obvious below; I'm new to MacOS after many years on MS-Windows;
First, I ran etrecheck and got the following;

Note that I had no heavy CPU processes like stobston had. There are some processes using lots of memory though. Made me wonder, could it be a swap or contention issue? I have a Macbook Air, so 'swapping' doesn't mean what it used to mean. Anyway, I tried closing Excel and Finder. Powerpoint was still slow. I ran etrechek again. WebProcess and mds are still running at the same memory usage; nearly half a gig between them. WebProcess is Safari; shutting down Safari didn't help. I have heard that Safari has had memory leaks, I don't know if that's true or not. mds is the MetaData Server for SpotLight. I had run Spotlight several times today, and also did a lot of desktop cleanup. That might have triggered mds.
I don't know how well Mountain Lion reclaims memory ( now I'm really getting into the weeds ), so I shut down MacOS and restarted it. This time, I started up PowerPoint first, with nothing else running. Problem solved. PPT is running fine.
Thanks again all for your inputs. An hour ago, I had no idea where to start. -
photoshop bridge on my 3 year old mac pro has become inoperable. In activity monitor is is using 180+ percent of CPU. I also get switchboard not operating. I deleted all of photoshop and bridge and reloaded them. Same problem. Does anyone know a solution. Setting up a new user account has been suggested.
Thank youHi @Tom,
Thanks for your response. "Camera Uploads" is a folder in which Dropbox deposits all my photos and movie clips from my cameras. It is a rather enormous folder likely exceeding several gigs of media.
The file path is
/Users/bpg/Dropbox/Camera Uploads/
I really don't know the difference between "media" and "events". I consider media a group or bunch of photos and movie clips. I consider "events" a specific bucket or container of photos and movie clips. If I should know more, a reference to documentation or an explanation of the difference would receive "This helped me." If you could explain how to get FCPX working again (it just won't do anything beyond the splash screen), I will provide "This solved my question."
Thanks for your help! -
Macbook Pro alternates running smoothly and lagging
My macbook pro will run smoothly for a bit, then lag for about 20 seconds, then run smoothly again. This keeps repeating. It began very suddenly. Any ideas on what could fix this? I tried the repair disk and safe boot methods but they havent helped.
When you have the problem, note the exact time: hour, minute, second.

Connected macbook pro to rca tv and not working
i have a late 2011 macbook pro. i've tried connecting it up to my old tv by..
minidisplay port -> vga -> tv/pc converter to RCA. i get a signal on my macbook pro picking up my tv
but on the tv i get tons of moving/flickering lines sometimes with a slight picture in no matter what resolution i use?
any ideas what i can do to make a proper image?How do you even get a signal? I just got a brand new MacBook Pro and I too am trying to connect it to an non-HD television. I can't even get a signal to show up on my T.V.

Macbook pro power cord frayed and not charging
Ive just noticed I have the same power cord problem. I plugged in the cord into my macbook and noticed that the light did not turn on. Upon closer inspection I noticed the wire was frayed and was real hot. I have not moved my power adapter or have had something happen for it to be that bad. Im not sure if Im still under my 1 year warranty plan thing, but I was wondering if I took it into the apple store they would still replace it. So if anyone has been in this situation and knows the best option, besides spending the 80 bucks for a new one I would greatly appreciate it.
Hope you feel better.
I assume the OP bought it there and can certainly go back under the 1 year and show them another melted one as there have been enough melted ones for them to know this is a bit of a problem. He can call Applecare as well of course.

Why is my (old) macbook pro so very slow and not able to receive gmail?
It seems to have given up. I have deleted spam, old messages etc. Any other ideas to speed it up?
Very slow to start up, seems unable to think...does that mean it is out of RAM? How would I check that?
Thanks for any help
GTry removing Dropbox from your startup items. Go to System Preferences / Users & Groups. Click your name and choose login items. You can remove it there. That won't delete it from your machine, just stop it from loading automatically. Reboot and see if that helps.
I'm not sure what "store monitor" is. I don't think that's for the App store, as I don't have it running on my machine. See if that loads from Login items while you're in there. -
Has this happened to anyone else?

I have had my macbook pro for 3 days, and it will not charge.
You have 14 days from the date of purchase to return your MBP. Personally, I would not waste my time "troubleshooting" if the normal solutions do not work.
Return the MBP for one that works before your 14 days are up and/or call AppleCare ASAP!!!
Good luck! -
My new macbook pro 13" just died and i can not turn it on. When i connect the power cort it also does nor charge. No light is commong on. I was working on battery power when it died and the battery was fully charged. What is the problem?
Take it back to the Apple Store for repair since it's still in warranty.

MacBook Pro turns on but will not load. Battery will power up and charge. The PRAM second start up seems to work, but the Apple timer continues add-infinitum. There is also a disc in the laptop so I can't load re-load software OS 10.6.1. How do I resolve this problem?
Try booting in Safe Mode by holding your Shift key down when booting. Also, try holding the eject key down when booting to eject the DVD. If you plug a mouse in and hold the clicker down when booting, that should eject the DVD.

Got a Riptunes MP3 player and put USB cord from MP3 player to MacBook Pro to transfer songs and my computer immediately shut down and won't power back up and won't charge now....what do I do!?
Take it in for a service diagnostic so you can determine if it's worth fixing or if you should buy a new one.
