Macbook pro Retina 15" a/c power connector melting

hello everyone!
not sure if anyone can assist here and have knowledge of past experience or even apple support calls resolution about my issue with my Macbook pro retina 2012 model --- the magnetic power connector from the magsafe 2 is overheating and has burned out 2 out of 5 pins on the connector itself and 2 of the laptop one i can clearly see them black and all burned out. this means the power to the laptop is now inconsistent and i have to giggle withe the adaptor to find the right position and once i do the light goes from green to orange after a few attempts --- but then the connect gets really hot ( as much as i can not touch it again )
question:
the laptop is out of warranty --- this seems to me a fault or a unique issue with this machine a/c power would it be looked at by apple support as a special out of warranty?
if not what would be the costs of repairing both he magsafe 2 (i have bought one now on the web ) and repairing the laptop power connection to ensure it does not happen again and burns out the machine or even god forbid it catches fire?
regards

Please make a Genius Appointment and take it in for service.

How do I connect a 2013 Macbook Pro Retina to an Epson Power Lite 61p LCD Projector?

I am trying to attach an Epson PowerLite 61p LCD Projector to my 2013 Macbook Pro Retina, but I cannot find which type of adapter I need. I would assume whichever adapter is required it must connect via thunderbolt. However, I do not know if the required adapter is a "Mini Display Port to VGA Adapter," "Apple Mini DVI to VGA Adapter," or a "Thunderbolt to VGA Adapter." I would deeply appreciate your help and guidance. Thanks!

It does not matter whether you get an Apple adapter or a third pary one. What you have there is a Mini Displayport to VGA adapter, but as you know, your new MacBook no longer has an MDP port!
Thunderbolt to VGA adapters do not exist but there are plenty of HDMI to VGA adapters out there:

Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?

Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?
E.g. Dell allows you to plug the laptop into AC power but prevent battery charging.
Note: I do not want to physically remove the battery.
If there isn't an option on Mac OS, is there anything I can download to bypass the battery when I want?

Thanks for linking me! Wow I had no idea the clock speed would be cut so severely! What a bunch of rubbish, as if the AC won't provide enough power!
I guess the only solution to my question would be an app which virtually disconnects the battery but tricks the mac into thinking the battery is still connected. I'm just surprised Apple haven't yet started to build prisons for the government - considering how well they lock up their software and hardware!

Changing Power Button settings on a MacBook Pro Retina

Is there any way to change the power button on the MacBook Pro Retina to press twice to open power down window? I sometimes press power down button instead of delete, it's kind of annoying...

@Nightshade_one - When the firmaware update is available it will show up for you under the Updates tab at the Mac App Store. Install the update, and go to Sys Prefs > Energy Saver to enable Power Nap.

Macbook Pro Retina 13'' - Power button and sleep mode

I just updated my Mac, which is the latest Macbook Pro Retina 13''. All of a sudden, it refuses to enter sleep mode when I press the power button, which worked perfectly fine before the update. I now have to manually enter sleep mode from the monitor. After entering sleep mode, It works fine to press the power button to make it work again, but not reverse. Why?
Thanks in advance!

I have this problem as well. Worked perfectly before I updated to OS X Mavericks (10.9.2).
Now I have to hold the power button in for it to sleep or click on it for a few times. But there is no problem when I'm going to wake the computer up, just a single push and it works fine. Is this a software issue or a hardware issue? Any respond from Apple regarding this issue and how to solve it? Or should i contact my retailer?

MacBook Pro Retina 15" Auto Power Off

Hi,
I have "auto power off" issue with my newly bought MacBook Pro Retina 15".
This problem is very annoying, my MacBook Pro just auto power off, where I check the battery is 100% fully charged.
The first encountered was about a month ago, the night I cannot turn on my MacBook Pro at all, the next day I sent it back to Apple Service Centre. The technician open up the bottom part, reset the battery by removing the battery cable, plug it back. Then turn on and perform some diagnosis test.
It was working fine for about 2 weeks, and now the "auto power off" happen everyday.
I have repartition my SSD drive to 2 partitions using BootCamp and installed with Windows 7 x64.
At first, this problem happen when I boot into Windows 7 with BootCamp, at first, I thought this problem is due to Windows Drivers, and I have no choice but purchase Parallels Desktop, to run my Windows with OSX 10.8.2. After the Parallels installed, I upgrade my second partition to run Windows 7 concurrently with OSX, it was running fine on the first day! And I thought it has solve my problems, unfortunately the next day, this problems occurs again.
I suspect this is due to hardward failure, something to do with the battery. Looks like the drivers is telling the Operating System, battery is 0%, and it just turn off itself.
Anyone experience this? Please share your experience or advice what should I do next?
Regards,
Dave

Hey Dave. Yes yes yes! Try reading through the thread below. Especially at the end. It has to do with an 'autopoweroff' setting that appears to be new and annoying.
When plugged in, goes from sleep to hibernate after 4 hours of sleep (or 14,400 seconds).
Very easy to turn off.
This after many hours of research and discussion with no help from the folks at Apple.
Basically, to query the settings (enter this from Terminal):
pmset -g | grep autopoweroff
You'll see the autopoweroff set to '1' and autopoweroffdelay set to 14400.
To actually turn that 'feature' off:
sudo pmset -a autopoweroff 0
(then enter your Mac password)
Now it will just sleep when plugged in and not go into hibernate.
You can also tell the Mac how long before it powers off via the autopoweroffdelay setting (if you like this silly feature), but I just turned the sucker off.
Here is the thread:
https://discussions.apple.com/message/20819713?ac_cid=tw123456#20819713
Hopefully, that's the same problem you have, and it will quickly fix it.

Power button and voice control buttons won't work on my macbook pro retina

I found that my power and voice control buttons won't work on my new Macbook pro retina. I can't shut it down or restart it in any way. And Im afraid if I force to shut it down I can't turn on it cuz the power button won't work. What should I do? Any idea???

Please read this whole message before doing anything.
Back up all data.
Quit Facetime and Messages if either is running.
Step 1
Hold down the option key and select
Go ▹ Library
from the Finder menu bar. Move the following item from the Library folder to the Trash (either may not exist):
Caches/com.apple.imfoundation.IMRemoteURLConnectionAgent
Leave the Library folder open. Log out and log back in. Try the applications again. If they work now, stop here. Close the Library folder.
Step 2
If you still have problems, quit again. In the Preferences subfolder, there may be several files having names that begin with any of the following strings:
com.apple.imdsmsrecordstore
com.apple.imservice
Move them all to the Trash. There may also be a file with the name "com.apple.imagent.plist". Move that to the Trash too.
Also in the Preferences folder, there's a subfolder named "ByHost". Open it and do the same thing.
Log out and log back in. Test again.

TS1713 2013 MacBook Pro Retina 15" Power Cable Black Gunk (Ink-like)

Hi folks,
I have a 2013 MacBook Pro Retina 15" and I bought a spare power adapter for it (85w). Today I went to pick up the cable and my hands were covered in a black gunk. I looked down and the cable had ink-like gunk on the cable? When I went to rub it off, the white coating to the cable seemed to be burned off and showed a tan undercoat.
Nothing was spilled on it or anything, it was just on the floor near my computer (not near anything that could burn the cable or something).
Has anyone had this happen? What the heck happened?
- Concerned

In a word, yes.
The video out capabilities for the 13" and 15" retina MBPs are the same.

My plan was to use the the thunderbolt ports to the monitors DisplayPort plug. Can the 13" Macbook Pro drive 2 external screens @ 2560x1440 I'm happy to shut the macbook lid if necessary.
If the 13" can't do it, can the 15" model with it's discrete graphics card?

Why not the Apple Thunderbolt screen, well I prefer a non-reflective screen in the office, but If I can't do it with the Dell's can it be done with 2 27" Thunderbolt monitors from the 13" Macbook Pro?

In a word, yes.

How to get new Macbook Pro Retina (late 2013) to detect external monitor via HDMI?

Hi everyone, this is my first Mac and for the most part it's been really, really wonderful.
This is my first major glitch: I cannot get it to detect my external display: It is an ASUS PA248Q, manufactured Aug 2012.
The HDMI cable according to my Amazon history is at least 1.3c from 2010, "Fanatic Digital Imperial Series Gold-Plated HDMI Cable (6 feet)".
It works with perfectly connecting an AmazonTV box to an old Samsung TV, with vivid clarity, unlike our cableTV signal.
Just in case, I have a new HDMI cable on order, which claims to be of newest standards.
The Macbook Pro Retina (late 2013) has the standard Intel Iris from the Haswell chips, as well as Nvidia GT 750M, the latter which I don't think has been used yet.
The ASUS display says: HDMI NO SIGNAL.
I have tried shutting them down and replugging the cable. I don't know what the ideal order is. The Macbook Pro is plugged into AC power, as suggested.
In System Preferences>Display, I press the Option key to select "Detect Displays" option (seriously unintuitive).
I have also tried resetting the NVRAM:
I shut the machine down. Pressed the power button, then quickly held the quadruplet: Option-Command-P-R (a double handful) and waited for the machine to chime a 2nd time. Tried to detect external display no luck.
Next, I reset the SMC:
I shut the machine down. Then I pressed Shift-Control-Option-Power for about 5 to 10s. Then I turned on the machine normally.
NVRAM & SMC steps were from an old youtube video, as the instructions I had did not explain how to do so clearly.
Please let me know if I"m doing something wrong.
Seems so exorbitant to pay $350 for Apple Care; that's a the cost for a whole new cheap laptop.
I will search the forums again. If anyone answers this, thank so much!

Hello there, willr314.
It sounds like you've covered most of the practical steps found in this Knowledge Base article:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573#1
No video or no signal, image distortion, "snow," or flickering
Check connections
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 system
You 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.
The article does offer some additional links and recommendations as well:
These articles may offer additional assistance and information about displays and video adapters:

MacBook Pro retina 2013 do not start and no light on the magsafe

Hello
I have a MacBook Pro Retina 2013 13' core i5 2.5 8gb ram
My mac was open, connect to the sector with full power. I left it the time to lunch and when i came back maybe 2 hours after my mac was off, and no light on the magsafe.
Impossible to start it.
I tried the key sequence, nothing worked.
I used the magsafe of a friend who have the same model, i had i green light for 10s before it turn slowly off. and nothing worked too.
One of my neighbor on the same building, had the same problem at the same time, computer open (not a mac) and it turn off impossible to start it, he had to disconnect/reconnect the battery to solve the problem.
May it be a power surge?
Did i need to open it and disconnect the battery on the motherboard?
Thank you for your help.

A Few things to try if you haven't already:
1. Try unplugging the charger from both the wall and from your MacBook Pro. Now, make sure the powerpoint the MacBook was connected to works by plugging it in any electrical appliance you have. After unplugging the test electrical appliance and verifying that everything is OK with the electrical source, wait a minute or two and just plug the charger back into your MacBook and the powerpoint.
2. A possible problem could be a MagSafe port not working correctly. Look for any kind of debris inside the port that might prevent it from connecting the power adapter correctly to your MacBook. On the adapter, take a quick look at the DC connector for any type of debris and carefully check if any of the pins are missing, are bent, or stuck down.
3. Try a quick restart. Just press CMD CTRL ALT EJECT For about 5 seconds.
4. Try CMD, CTRL and POWER for about 5 seconds.
5. If none of this works, my last suggestion is removing the battery connecters and power supplies ect and holding the power button for a few seconds and reconnecting everything.

MacBook Pro Retina hangs on startup when connected to Thunderbolt Display

I have a MacBook Pro Retina and it's basically almost always connected to my Thunderbolt Display. Each time I start it up, I open the MacBook just slightly and press the power button - and almost instantly the MacBook goes ontop the startup Login screen and at this point is where I close the MacBook and login through the Thunderbolt Display.
Since last night for the very first time - My MacBook Pro hangs on a white screen and takes a long time before going to the Login screen. I've tried to swith the Thunderbolt Display off from the mains - I've also tried to boot up my MacBook on it's own without it being connected to the Thunderbold Display and all is fine (it almost immediatelly shows the Apple logo and then staright onto the Login screen then BUT as explained, as soon as the MacBook is connected to the Thunderbolt Display and I power it up - it hangs on a white screen for about 30 - 60 seconds before it goes to the login screen!
I have no idea how from one day to the next this could happen? Perhaps it's some Apple updates I've made recently which I cant really recall because I usually just update software when required to do so.
Hoping anyone can help.

Does the battery charging in the macbook pro retina automatically cut off when the battery is fully charged?

Does the battery charging in the macbook pro retina automatically cut off when the battery is fully charged? or does it continue charging?In which case,is it better for the battery life to switch off the power supply or leave it on while using the macbook?

Yes, and the pilot light on the MagSafe2 connector changes from orange to green. If you unplug, you will start draining the battery again, whereas if plugged the Mac will take power from the brick and leave the battery in a charged state.
