Macbook Pro retina will not turn on

I bought a 2012 Macbook Pro Retina 13" off Craigslist today. It will not turn on. I tried resetting the SMC and disconnecting the battery and reconnecting it. It will still not turn on, the battery has been charging for 2 hours already and it's still amber on the magsafe. It still has warranty coverage until 2014 so my next stop is the apple store. I thought I could fix it myself but it is pretty tough to narrow down the cause.

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

When i tried to turn on my mbp today it only turned on for like a second and then shuts off. The light on the front turns on and the battery is fully charged, but it just turns off in a second

Hi, I have an Early 2008 Macbook Pro and I used it this morning but two hours later, I found it off. When I push the power button, the white light briefly comes on but it doesn't sound like it's starting up. When I hold the power button down, the white light comes on solid for about 5 seconds, then flashes rapidly. During this time I can hear the DVD drive and other components kick on, but once the rapid flashing stops, all power is lost again
The problem: Mac will not turn on.
1. If I hit the power button it is trying to start working (white light is blinking, HDD rotating, CD noise and so on), but gets shutdown as soon as I release my finger from the power button.
2. The maximum "Working" time is about 5 secs. During this time fans are working, white light is lighting, HDD working, CD does its usual noise. At the last two seconds white light starts flickering.
3. If I remove all memory slots it is working as usual!!!, I mean working without pressing a powerbutton constantly... and asking for a memory of course.
How it happened: well, it is usual thing then you are in hurry. Accidentally I hit restart. I didnt want mac to load again, so I did a force shutdown (5 secs an a power button). Thats it.
What I tried to do: I did all those "shaman" hotkeys to restart SMC. I spent a day!!! by driving around my city and asking Apple providers to fix it with no luck.
What I am planing to do:
1. I have an Apple service center here in the Tallinn who are ready to do some diagnostics. The only thing is - I dont trust them my HDD. So I am gonna clone my hard drive data somethere before they get my mac in their hands.
2. As soon as diagnistics is done I will get a price offer to fix it. It definitely wont be a cheap, since my mac is year and two months old (funny, two months and you are screwed).
3. If it will be too expencive I gonna do DIY repair.
What I would like to say to the Apple: please investigate that problem. The motherboard is definitely working. I can not fix it myself with no necessary equipments here, so I have to do expensive motherboard logic purchase.

Hi rightturn,
Thanks for replying.
I am still not sure about the success story. According to the http://www.xlr8yourmac.com/feedback/MacBookProvideofailure.html topic and comments you have to have "chime" sound and numlock (or capslock ???) button to work. Those two are the main criterias to pass the nvidia failure test.
Another thing is the USB which is should be powered on as well.
As you could see on the youtube video this macbook does not have chime, and keyboard seems does not work too.
So... will see what happens next after the weekends I am gonna call them for an updates.

Macbook air's fan not turning off and it will not sleep when the lid is closed?

I downloaded OS X Mavericks yesterday.The fan will not turn off. It runs whenever i turn on the computer. The computer does not turn off when i close the lid, and the fan still runs. There is also no battery icon anymore on my home screen. Is this just a bug with Mavericks? My computer is a mid 2012 edition.

Cloned MacBook 2012 HDD will not boot

I have a MacBook Pro 2012, Mountain Lion factory installed on a 5400rpm 750GB hard drive. I am attempting to clone this drive to a new Seagate Momentus XT hybrid, same 750GB capacity. I have done so three times now, once using Disk Utility, once using CCCloner, and once using SuperDuper. The clone seems successful and the drive will boot from the external caddy. After it is installed in the MacBook, however, it will not longer boot, isnt even seen by the machine and all I get is the little folder with a question mark on it. I also attempted to install the Momentus XT internally and boot from the original HDD and do the clone in reverse, but to my astonishment, the MacBook didnt recognize either drive, and offered me only the internet restore option. I am stumped. I've done this mutliple times before on older MacBook Pros without a single problem, most recently on a MacBook Pro 2011. Anyone have any suggestions?

You need to prep the drive properly. If the new drive is in the computer then boot from the external drive you are replacing.
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Upon completion of formatting:
Clone Lion using Restore Option of Disk Utility
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Select Disk Utility from the main menu then press the Continue button.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

MacBook Pro (late 2012 15") does not turn on unless I reset NVRAM

Since upgrading to Mavericks, when I power-on my MacBook Pro (non-retina, late 2012, 15"), I get a chime and the power light (right of front bezel of unit) comes on for a moment, then nothing. Screen stays black never comes on. If I power on with resetting NVRAM (hold down Option-Command-P-R), I get the expected double-chime, and the MacBook will come on as normal. I have a Samsung 256gb SSD and 16gb of Crucial RAM.
Is this Mavericks related? I never once had this issue in Mountain Lion. Any suggestions on what I can do to prevent it in the future?
Many thanks.

MacBook Pro screen does not turn on after using external display?

Hello,
I am using a 15 inch MacBook pro from mid 2012. At work I connect it via mini-display port to an eternal monitor. Recently however, sometimes after I go home and try to turn the laptop back on, it turns on, but the screen does not. If I connect it to another external monitor, it uses that as the default display. Sometimes I can just restart the laptop and everything is fine, other times I have to turn it back on while holding the shift key in order for the laptops built in display to be used.
After work, I unplug the mini-display port, and then power off the laptop.
Can anyone help me understand why this may be happening so I can prevent it from happening again?
Thank you.

Try a smc reset:

Also try a pram reset. Power off, power on holding the keys: Option, command,P,R(no commas) press the keys before thr start chime, then hold them till you hear the chime 2 times. Release and reboot.

My MacBook Pro(early 2011) not turning on

I've had this mac for 5 months already, hasn't given me a problem until now. It was working fine when I used it this morning. I left it plugged in and went to work. So when I came back from work, I tried to turn it on but it doesn't. Every time I press the power button, I can hear the hard drive trying to turn on but it turns off immediately. It indicates that the battery is full but it doesn't turn on. I recently upgraded the ram from 4gb to 8gb about 2 months ago.
Is it a hard drive failure? Ram? or should I give it some time and then try again? Or take it to an Apple Store?
Thanks
I made a video so you can understand it better.

Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Macbook Pro Screen Does Not Turn On

I just updated the firmware my Macbook Pro (late 2007-2008). It has been running on Mountian Lion for about a month, and the update was the newest set released by Apple. The firmware was installed and the laptop rebooted. I heard the chime, and then the computer screen never came on. I can turn it on, but the screen never comes on. The white light on the front of the computer comes on, and does not blink, even if the screen is closed. I have held the power button down to force shut down, and it will eject a disk if one is in the drive, but the screen still does not come on. It makes no noise when I reboot it manually.

Macbook Pro(Early 2011) not turning on; Flashing Orange Light on Charger

So yesterday, I did a teardown of my Macbook pro (early 2011) in an effort to clean the keyboard because some keys weren't working. I used rubbing alcohol and As I was putting the keyboard and trackpad connectors back in, I heard the computer making a startup/shut down noise so; I realized I neglected to unplug the battery - out of fear of shock and impulse, I unplugged the battery quickly. The computer shut off and, ever since then, my computer won't turn on. When I plug in the charger; it initially gives me a very faint green light, and when I hold on the power button it changes into a very dim orange blinking light.
I've tried:
1) Resetting the SMC (No such luck)
2) Unplugging the battery; letting the charger charge the motherboard overnight (No luck)
I'd really appreciate some fresh ideas; just to reitterate, it only stopped working the second I impulsively unplugged the charger. So, can a battery die from something like that? Short circuit? Any advice would be really appreciated as I'm in the middle of finals week and really need it.

My only issue with that is that there weren't any hardware issues before i decided to open it up. I know the apple people will be very eager to charge me for something in not convinced is a hardware issue. I just get the feeling i screwed something up while I was putting it back together. I'll post a picture of my logic board soon to see if there's something obvious I'm missing

Finder extremely slow on a macbook pro, you can not turn off, and the color wheel appears to move any file

I have a MacBook Pro 2GHz i7 early 2011, 16GB RAM, a 128GB SSD and a 500GB standard. The OS is mountain lion and a month ago my finder is very slow, when moving a file appears the color wheel, also when you send a file to the trash. When you turn it on, the finder takes a long time to be active, the other apps work perfectly. When you turn it off stays white background with the spinning wheel, but never fails to go off. Heat much m'as than before and make lots of noise sinks. Sometimes also starts with the date changed to 2008, not always.
I tried to repair disk permissions, reset pvram even I formatted from a usb and the problem continues.
Please help.

First, back up all data immediately, as your boot drive might be failing.
A common cause of a slow user interface is a large set of image or video files on the Desktop with preview icons. If you have more than a dozen or so such files, move them to another folder.
Another possible cause is iCloud activity, especially Photo Stream synchronization. If applicable, uncheck all boxes in the iCloud preference pane and see whether there's an improvement.
Otherwise take the steps below when you notice the slowdown.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Select the 50 or so most recent entries in the log. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message. You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Macbook pro retina does not turn on-

was fine when I closed it and left it to charge overnight
This happened before and I took it to a Genius at the Apple store who took it in the back and brought it back on. Didn't tell me what he did but now I'm travelling and can't go to the store. Does anyone know how to magically make it come back to life?

Look at this Apple support article:

Macbook is not turning on

Hi guys,
For some reason my MacBook Pro (2009) is not turning on anymore. Yesterday evening it still worked perfectly though. I read a few times that I only have to remove the battery and out it in again but this didn't help so far.
Any other ideas?
Thanks a lot.
Cheers
Frank

GrandCrue1984,
Can you boot into your Recovery partition or will the machine simply not power on at all?

MacBook Pro is not turning on and keeps beeping. Please help!!

My MacBook Pro 13" is not turning on. It keeps beeping three times then pauses and repeats. It froze earlier today and I had to force a shutdown. I've done this before and it's worked fine. How do I get it to work again??? Please help.

Three beeps at startup indicates that your RAM hasn't passed the integrity check and one of the modules is faulty.

My MacBook will not turn on and when I connect the charger it has a very dim light

I have just come back from holiday and went to turn on my MacBook, but it will not turn on
I connected my charger and the light is very very dim.
How do I resolve this? Will I end up losing all I have saved on it? Please help!!!

There may be something corrupted in the system, and a certain kind of reset may be able to help...
•Intel-based Mac: Resetting the System Mangement Controller (SMC)
http://support.apple.com/kb/ht3964
If that doesn't work, check instructions carefully and repeat if necessary, see about taking the computer to an Apple Store and try to call ahead for Genius appointment; or contact an authorized reseller with product specialists and service.
Some users ventured into their out-of-warranty macbooks to check the actual cables going from the battery compartment to the logic board, apparently some batteries unplug. Others you can't get into.
I see following post/link says several things, can't vouch for any except ^ the SMC reset support page above: https://discussions.apple.com/message/23996241#23996241 - Also, check the right side in this recent thread for links to similar topics.
{In order to make a backup at this late a date, you'd need power to the computer; enough to try & see if something as quaint as 'Target Disk mode' would work... If your Macbook is one with Firewire ports.}
•How to use and troubleshoot FireWire target disk mode:
http://support.apple.com/kb/HT1661
With FW TDM, the failed computer can sometimes be powered up holding the T-key down, and a firewire icon would appear on the screen; then one could go about attaching or using a FW cable of correct type and connect it to another capable computer, then the failed computer's HDD would appear as an external drive. In the past, it was possible to clone or copy a drive from a computer that won't boot to another hard disk drive. Or at least copy stuff of that does not require the system to function along with the saved files.
Good luck & happy computing!
