HT204267 My 2012 15" retina macbook pro won't turn on, sporadically

My macbook pro will go through phases of working fine, and not turning on AT ALL. I have reset the SMC, pRAM, bought a new charger, etc. But sometimes, I'll close my computer (which has excellent battery life, mind you) and it will, seemingly, die. No problem, right? Plug it in, start it up- NOPE! I'll plug it in for hours; until the charger turns green, even. And hold the power switch like there's no tomorrow. Trust me, all sorts of ways with different durations. It just will NOT turn on. No chime, no action with the fan. It just gets really hot after a few minutes. Then I'll leave it for a good 24 hour day alone. Only then, will I plug it in, and it will magically turn on. Bottom line- very worrisome, and untrustworthy problem I have. Are there any ideas?? Thanks in advance, everyone.

I have the same problem , suddenly my MacPro stoped, and the charger light is hardly can be seen, it is not charging and not turning on. I tried to hold power button 15 second and ...so on ... but didn work. Any one have other solution please?

Late 2012, 13'' Retina MacBook Pro, Display bug

Hello, I am having a late 2012, 13'' Retina MacBook Pro(i7, 8Gb). Last year I upgraded to Mavericks. Immediately after upgrading I notice that my MacBook is bit slow. I always keep my OS X up-to-date. Last month I noticed something really strange.
1. Whenever I manually put my MacBook to sleep by clicking sleep command under the apple logo (top left hand corner of the screen) then the way the display turns off is not normal. I mean its not smooth as it was earlier. I have compared this with the new hardwares (MacBook Pro's) in the apple store.
2. After I put my notebook to sleep, when I try to wake it up within 5-10/15 mins, the screen flashes very quickly before entering password.
These issues are bugging me a lot. I also have apple care. I called senior adviser and described the issue. I got scared when he mentioned that there might be some issue with my logic board/graphic card.
I also performed Apple Hardware Test by myself and also booked an appointment with the Apple Genius Bar guys but everything came up normal.
Is there any particular test I need to mention to the Genius bar guys to test with there unique hardware checking tool?
Note: I did clean install of OS X couple of times, also did SMC reset & PRAM reset.
Recently I updated with latest OS X update 10.9.4 hoping that this issue will resolve but no luck.
I am wondering whether any of you guys have experienced similar issue or I am the only one. Is it something I should worry about because I still have apple care and if it requires major hardware change then I can easy get it done without paying any $$$$. I know logic boards are pretty expensive.
Thank you!

The screen glitches that have been most likely when upgrading to 10.9.3 are quick, brief flashes of yellow, pink, etc., light on screens immediately before login. It doesn't sound as if you're having that problem.
If QuickTime won't record the glitches, then it's unlikely to be a problem with your GPU - most likely a screen glitch (if that) or a OS X glitch, nothing related to Flash Player.
However, if I were you, I would take the machine into your local Apple Store and have the techs run some tests. They may want to install OS X anew, so I would make certain that you have a backup before taking your machine into the techs.
Good luck,
Clinton

OSX 8.2 new Retina Macbook Pro won't wake from sleep.

Since upgrade to OSX 8.2 new Retina Macbook Pro won't wake from sleep. Tablet lights are on in morning and fans running like crazy, but it requires hard quit and start. Tried with no apps running, no change. It was fine before this last update. Wasn't the recent firmware update supposed to fix this issue? It seems to have started one for me.

I have the exact same problem with my Macbook Pro OS 10.8.4. What happens is: I work on the train, press cmd/alt + eject to put to sleep..pop it in my bag...get home or office... open the lid...and nothing! Battery indicator shows I have plenty of juice but it will not wake up no matter what key I press.
The only difference between use on the train and home/office is the plugging in of peripherals and mains power. It happens sparadicially, perhaps once or twice a week and I always send a 'panic report', so somewhere there will be approx 20 reports of this fault at Apple.

My MacBook Pro won't turn on, only a white screen with spinning circle, I've only had it a few weeks! Any ideas what is going on?

Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
If this doesn't work then you will need to erase the drive and install Snow Leopard from scratch:
Erase and Install Snow Leopard
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
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. When completed quit DU and complete the Snow Leopard installation.

Depends upon what you mean by it not turning on, there are various causes.
Is the power button pressed and nothing happens? Disconnect all other devices, then a SMC and NVRAM reset.
Is there a white screen and nearly nothing? A hosed EFI firmware.
Is there a grey screen and a loading bar that gets stuck? Either a failed firmware update or corrupted drive/OS X.
Is there a grey screen with a spinning wheel? Bad third party or Apple at boot kext file.
Are you loading but not able to log in? Possible corrupt third party software designed to startup upon login.

You need to hit the "reply" button on post to whom your responding too, it's hard to tell if your responding to me or someone else.
small button on the side of the computer and didn't lightting up( no reponse at all). is their any problems do think with the battery?
Usually if your battery is dead because it wasn't charged you can do the SMC Reset and then check the Magsafe if it's connected and showing the orange light, then let the battery charge up.
Once the battery charges up, the computer will boot normally and then you have to reset the PRAM, time, date etc.

my macbook pro won't start up...it begins to boot up.but stops short before the screen comes on. the light which indicates that the computer is on dims and the booting.stops. any tips?

I had this same exact problem from a couple days ago and it was fixed this morning, I remembered reading this and HAD to come back and help you. I left my macbook on all night and let the battery completly die out, after that I recharged it and it was back to normall. I hope this works for you as well!

Help - MacBook Pro won't turn on

Help - my macbook pro will not turn on even though it is plugged in. Holding down the power button is ineffective. The power cord has the green "charged" light, but when I plugged it in, it wasn't charged and never did charge (the light never was orange). The computer worked perfectly this morning.

Will it not turn on at all or do you just get a gray screen?
If a gray screen, look at this:
https://discussions.apple.com/docs/DOC-5282
If it does not turn on at all, try a SMC reset:

If the reset fails to bring life to the MBP, make an appointment at an Apple store genius bar for a free evaluation.
Ciao.
