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.

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.

MacBook Pro won't turn on and won't charge

My MacBook Pro will not turn on and it appears to not charge. my charger blinks a orange light when I plug it in but the light is very dim. any suggestions?

Bring it to an authorized service center and have them try one of their chargers on it. If the charger doesn't work, then have the battery replaced. If the battery being replaced doesn't charge, replace the power supply.

MacBook Pro won't turn on and it won't charge

My MacBook has been working fine and has been charging until now. I left my laptop in without it being plugged in and I presume the laptop died when it ran out of battery. I plugged my charger into laptop but I noticed that there was no charging light on the mag lite charger. I tried plugging my laptop in at different plug sockets and I've tried using a different charger but my laptop still won't charge it turn on. I've only had it just over a year. Any ideas anyone?

HT3964 Macbook pro won't turn on and won't charge

Hi. I just bought a macbook pro 13" last year August. Unfortunately just today when i used it and plugged my iPad to sync, it shuts down unexpectedly. Then i tried charging it as i thought it maybe because the battery is out but no. The charger won't work as well. I borrowed my cousin's charger yet it still dont work. My charger is working eventually to my cousins mac. Anyone who can help me? I tried SMC but it doesnt work. I need my MAC.

You need to take your machine into your local Apple Store or an AASP and have them run diagnostics on it. Sounds as if you've a hardware failure.
Sorry,

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.

My MacBook Pro won't turn on and is fully charged

I watched a Dvd this morning on my Mac book pro it was plugged in and fully charged when I shut it down. I unplugged it and put it up. When I got home it will not turn on. It shows green light (for fully charged) but nothing when you touch the power switch. Any advice?

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.

Macbook Pro won't turn on and no charge?f

Hey, I bought my mbp around September of 2009. Last night I put it to sleep, and when I woke up it wouldn't turn on. The battery indicator shows only 1 green light and flashes for a couple of seconds. When I plug in my charger, there is no light, as well. What should I do?
Thanks in advance!

Hi Ezam
It's interesting that you say that it's a new battery charger, do you still have the old one and have you tried that?
It sounds like a problem I had with one of the Laptops where I work. We were experiencing problems with the charger so we bought a new one, didn't think anything of it and the Apple Store didn't ask any questions - why would they.
After a few weeks the Laptop seemed to be losing it's charge, so we called in our support contract, turned out that the Adapters are very slightly different and the one we had although it worked was not quite the right one for the Laptop we had (This was one of the older style chargers with the jack type connection).
Not sure if this rule still applies with the MagSafe but might be worth looking into, sounds like the chargers not getting the power there. The 1 battery light you're experiencing is the sign that the Battery doesn't even have enough juice to light one light.
The service Battery warning seems to be a common one coming up at the moment with Snow Leopard but it shouldn't stop the machine from turning on, especially as you can run the MacBook without a battery in (not advisable mind).

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.
