MacBook Pro won't turn on even with green light on charger

i have a 2010 MacBook Pro. The battery has been permanently dead for years but it still turned on as long as I had the charger connected. Eventually the charger stopped working so I bought a new one. The light is green on the charger but the MacBook won't turn on now. I tried that reset thing as well as opening up the bottom and disconnecting and reconnecting the battery and that didn't worn either. I pressed the button on the side and there's green flashing lights so its definitely getting power it just won't turn on. I don't know what else to do at this point.

Was that 'reset thing' a SMC reset?

If so, a new battery may be the cure but bring the MBP to an Apple store genius bar for a definitive evaluation first.

My MacBook pro won't turn on, even though it's fully charged. I can hear a disk chime but nothing on the display. Help?

I'm having an issue with turning my MacBook pro on. It's fully charged and when I press the power button I hear a disk chime but nothing happens on the display. Can anyone help please?

Tried connecting the cable? Still won't start?

Broken Macbook Pro won't finish copying even with target disk mode. Help!

Hi,
I'm helping someone with a Macbook Pro 2010-11. It worked for a few years but eventually degraded last month when it wouldn't go 10 minutes without displaying the rainbow loading ball. Possibly a hard drive problem.
The owner never backed any of the computer up. I am trying to salvage their data before it's lost. The computer can power on. I have been turning the computer on and salvaging most of the data from numerous trips with USBs until it crashes, and then moving on to Target Disk Mode. The computer turns on slowly, displays the rainbow ball every minute or so, and never finishes copying or exporting anything. It still seems to be degrading.
I still need two things: One is a large folder with thousands of old OUTLOOK e-mails created on an old PC (which the owner no longer has).
Second is the folder/autobackup where OUTLOOK for Mac stores all the e-mails and settings.
I have found the folder -- I think it is the Main Identity or Office Identities. Am I correct? Will this bring back OUTLOOK on the newer Macbook Pro exactly like on the old one? I also know where the old e-mails folder is, but when I try to transfer either folder through Target Disk Mode on the newer Macbook Pro, it stops and gives me the "Some data in _____.olk14msgsource could not be read or written." AKA error code -36, halfway through the transfer.
I have tried exporting OUTLOOK on the broken Macbook Pro to a .olm, but it gets stuck halfway and gets stuck back on the rainbow ball. Then I shut the computer off. I have also tried going into the folders through target disk mode and deleting the .olk14msgsource files that are problematic, but there are too many of them.
Please help! The owner needs these files and OUTLOOK exactly like it was!
Thanks!

Macbook Pro won't wake up even with power adapter connected

If I use my Macbook to the point where the battery completely die, it will not power up again even with the power adapter connected. It takes about 15-20 minutes of charging before it will wake up again. It seems as though it can't draw power directly from the adaptor, but must wait until the battery is sufficiently charged, and draw power from the battery. I can't imagine this is a design decision. Any help?

Part of this time may involve attempting to read a damaged sleep image file, bewlatbrutha.
You should note, too that the batteries in these computers have a built in microprocessor of their own to try to prevent them from being damaged by discharging too deeply. If you discharge to the point where even the battery's own processor has to shut down you may never be able to resurrect your battery without outside help (and sometimes not even then). Almost all Lithium Polymer and Lithium Ion batteries (regardless of what they are fitted to) have this sort of protection. The battery has to have a certain minimum charge at all time to keep its own processor running.
Even without reaching this point it is not good for Lithium batteries to be regularly discharged to the point where the computer has to sleep or shut down. You risk severely shortened battery life if you do this regularly.

My relatives 2009 Macbook Pro won't turn on and isn't taking a charge.

Holding down the power button has no effect and when the charger is inserted, there is no green or red/orange light. All outlets are functioning and the computer was working as it always had the day before. Help?

Hi Cygnus and Lyra,
Thanks for visiting Apple Support Communities.
If the MacBook Pro doesn't respond when the power button is pressed, or seem to recognize the charger, these troubleshooting steps can help:
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

MacBook Pro won't turn on. Odd flashing light.

Hi Everyone,
My wife's MacBook Pro has failed to start. Strangely the button to open the lid on front flashes.
The computer recently had a new mother board put in. Feburary. Bit of a waste of money on and old mac. But there you go.
Now we can't get it to turn on.
Disk drive macs a sound but screen doesn't even turn grey.
Can't seem to reset PRAM. Get no chimes at all.
Any suggestions?
We live in Middle East, So would be a problem getting it to a Apple Store.
Please help.
Thanks,
Jamie

I have the exact same problem. It just started yesterday. I was able to start it up in Safe Mode by pressing Shift right after the start up lights went on. Usually you would do it right before teh chime but I had the same issue as you. It would not chime. I had to try it like 20 times before I hit teh right timing. I suggest you do the same while you are temporarily trying to use your computer. Safe mode is not idea as services aren't started and permissions are not full. So some applications aren't running very well in safe mode. I am taking it into the Apple Store tomorrow. I'll see how it goes and let you know.

What can I do if MacBook Pro won't turn on but the keyboard lights up ?

Hi, my MacBook won't start but the keyboard lights up, if anybody has any ideas what I can do to get it to turn on, I'd be forever grateful,

Try ooting into your Mavericks Recovery partition - by holding down the command and R keys shilst booting.
Once at the Recovery screen, open Disk Utility, slect your hard drive icon on the left of the screen (usually named "Macintosh HD" unless you'e renamed it) and click on the "Verify" button. If you get green text telling you that everything seems to be O.K., just reboot. If you get red text telling you that the drive needs to be repaired, click on the "Repair" button. If repair is successful, you should be able to bott normally.
Call back with results.

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.
