Mid-2009 Macbook Pro will not turn on

Hi Folks,
so my mid-2009 15in Macbook Pro will not turn on. I updated the OS to Mavericks in December 2013. I'm from California, but I recently moved to the Guam/Marianas area where it is more humid and generally around 87 degrees F all day. For the past month my computer has worked fine, albeit I did notice the fan was running a little more than usual. I usually would just put it into sleep mode when I would finish using it (apparently a bad idea based off of reading other posts concerning humidity and, more importantly, heat). One day I finished using it, closed it and the next day went to open it; I could hear the fans start to work, but then it stopped. It hasn't turned on since. You press the power button and nothing happens. I tried all the troubleshooting stuff.
So, my question is this: what do you think is the problem? Moreover, how much do you think it could cost to repair it? My experience with computers suggests to me that it's probably a dead motherboard. I'm wondering if it's worth trying to salvage this thing or if it would be prohibitively expensive. There are no Apple stores in the area to take it in to get advice unfortunately.
Now, I just want to vent a little frustration. I have many apple products, and I've even switched my mother over to an apple computer, but now that I need some very basic support, apple doesn't provide a contact e-mail or a free chat? I think charging someone $19 for 'one time assistance' is ludicrous. I bet if I brought this into an apple store I could at least get some advice, and thus get some idea how I want to proceed with repairs or not. I suppose I'm also rather frustrated that my macbook, which I have been most happy with all these years, breaks because I go somewhere a little more humid and generally warmer? It would appear that the hardware failure is connected to the climate. This makes me skeptical about purchasing another mac if it can't handle a little humidity. (I have not spilled liquids on it, nor have used this computer while transitioning from an air-conditioned/humid location which could potentially cause condensation). I do not think I'm being unreasonable (yes I do think a $2500 computer should not fail after less than 5 years), but if you think I am unreasonable, please enlighten me.
Thanks for any help. I really appreciate it.
Ken

Ken,
the “Important Handling Information” in the little white manual that came in the box with your MacBook Pro states that its operating temperature range is from 50 °F to 95 °F (10 °C to 35 °C), and that its operating range of relative humidity is 5% to 90% (non-condensing). If your corner of the Pacific is outside of these ranges, the manual states that “Failure to follow these handling instructions could result in damage to your MacBook Pro”.
I have no idea what problem your MacBook Pro has; since you’ve tried all of the troubleshooting stuff, you’ll need to somehow get your MacBook Pro to a qualified service facility to diagnose the problem. If the logic board does need to be replaced, it would probably cost hundreds of dollars for a replacement, and you might find that purchasing a replacement used MacBook Pro of the same model to be price-competitive with just replacing your MacBook Pro’s logic board.
If you find Apple’s out-of-warranty policies unacceptable, then your only alternative to venting would be to purchase your next computer from a different company which has out-of-warranty policies more to your taste.

My MacBook Pro will not turn on, bought a new charge still no power, My MacBook Pro will not turn on, bought a new charge still no power

My MacBook pro will not turn on bought a new charger and it still will not turn on

Then your problem isn't with the charger/adapter. Which model MacBook Pro do you have (e.g., "15-inch Late 2011")?
It's likely that you'd be best served by taking your machine into your local Apple Store or AASP and having the Apple techs run diagnostics. The diagnosis and estimate to repair should be free.

My macbook pro will not turn on and the charger is not lighting up

please help!! my macbook pro will not turn on at all, when i plug in the charger it will not light up at all, it suddenly shut down when i was using it.

Is there any charge left in the battery?
Press the button on the left side, near the front edge. If no green lights appear, battery is flat. And if the power brick ain't workin' (by virtue of its pilot light not glowing), then it will remain flat and the computer will not power up. If this is the case, maybe try with another power brick of similar size and see if it charges.
Else the logic board is toast and pitbull's on the money.
Either case, my gypsy crystal ball forsees a trip to an Apple Store or a Service Provider in your future...

My MacBook Air will not turn on. I get a white screen with the apple logo and a spinning star that just does that for hours

My MacBook Air will not turn on. I get a white screen with the apple logo and a spinning star (search icon). It will spin for hours and never go away unless I power off.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

MacBook Pro Will Not Turn On. Charger light flashing

Hi there all. I am having a problem with my late 2011 MacBook Pro, and I have tried everything. I was wondering if you might be able to help. I will describe the problem in detail:
This morning when I woke up and went to use my macbook, it said the battery was 50%, even though it was plugged in. I use it like a desktop, plugged in to a monitor and plugged in to power most of the time. I usually allow it to drain the battery every few days. Anyway, I rebooted it, and the battery was still going down. I tried various things, like unplugging it completely etc. I remembered that my friend had this problem last year, with her exact same model macbook, and she came to me, and I was able to fix it. So, I thought if I followed all those steps I would be fine. I reset the SMC and PRAM. At this point the battery was showing at 0% when the OS (mavericks) loaded, and then after a few minutes the computer switched itself off completely and with no warning. The light on the charger was sometimes showing orange but didn't appear to be charging after several hours. The battery indicator was flashing 3 times on the first light then fading. It was not turning on at all now.
So, I decided to do what I did to my friend's macbook to fix it. I unscrewed and removed the back cover, then i carefully unplugged to battery from the motherboard, and left it unplugged for about 20 mins. I also pressed the power button for 5 seconds while it was unplugged. I then plugged it back in, and made sure the plug was correctly seated, put the cover back on, and plugged in the adaptor. to my horror, this did not fix the problem, as it did with friend's MB. Now the light on the charger was flashing from green to orange, and there was a sound like a hard drive spinning, also the status light on the front of the computer was flashing white. So, I opened it up again and plugged in the power adapter to see what it was. Actually, it is the fan. Whenever the light in charger is orange, the fan spins, then when it turns green, the fan stops! This is with the computer completely powered off. I tried removing the RAM and reseating it. I have tried unplugging the battery, and plugging the power adaptor in. It still does the same thing. There no response to the power button at all. I tried a number of different key combinations that I found on various web sites, it will not respond to and key combos with the power button. It seems to just be stuck turning the fan on and off for over an hour now. I will unplug it, so it doesn't cause any further damage.
does anyone know of anything else I can do? I cannot afford to call Apple or have it fixed. Usually, I am able to fix these problems in my own.. But I'm not sure what to do now.
Thanks in advance

Can you borrow a power adapter from someone and try that adapter with your machine? That would, at least, solve the problem or eliminate the power adapter as the problem.
If you have an Apple Store nearby, you should be able to get a free test and estimate for repair. It may be something simple, it may be something more complex. But if changing the adapter doesn't work, that's what I would recommend. If it is the adapter you're just going to need to buy a new one - and if you must do that make certain that you order a GENUINE Apple adapter.
Good luck,
Clinton

Macbook pro will not turn to almost have changed the motherboard and the power supply board

Hello,
A customer brought me to repair his macbook pro A1151, the computer flashed, I had to change the power board and the motherboard and the computer still does not turn.
The customer used a power supply with wire was déterrioré there were overheating the power supply board has traces of burns and a component of the motherboard is broken.
What may be another problem that prevents your computer from turning on?
Thank you.

Run an Apple Hardware Test:
http://support.apple.com/kb/ht1509
It may pick up some information that might give you a clue as to the unusual behavior.
Note: An error free AHT is not always definitive.
I still would go to an Apple store genius bar and have the MBP examined. It will be done for FREE regardless of warranty status.
Ciao.

My MacBook pro will not turn on after connecting to an external display

I connected my MacBook pro to a projector for a presentation using a VGA adapter. It worked for a couple of minutes, then my computer shut off and I can not turn it back on. It has never given any trouble before then. Now when I try to turn it on, the white led comes on briefly, then it makes a tone and nothing happens, the screen stays dark, any idea what is wrong????

My macbook air will not turn on all the way

When I try to turn on my AMcBook Air the screen will not get past the thinking circle

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.
