HELP MY MACBOOK PRO WON'T START UP

Help! I was using my MacBook Pro halfway and it suddenly turned off! My battery was flat when I turned on and so it shut down and then I turned it on again while charging. It was working perfectly fine then until this happened. Then there was problem with my charger. It was flickering very dim green to orange. It's still under warranty so I brought it down to the service center to get it fixed. I'm quite worried that there might be a problem with my HD as this laptop is for my school hence there's a lot of important data inside. I don't do back ups hence I'm doomed! Do you think there's a problem with the motherboard/logic board or the hard drive itself?

Help, my macbook pro won't start anymore

Hello all,
I have had some issues with my macbook pro lately:
A few weeks ago, my Macbook started freezing and making alarm sounds. I didn't do anything about it because it happened only a few times per week.
Suddenly it happened 4 or 5 times in a row, and after x times my Macbook wouldn't go past the grey start-up screen (Apple logo loading). So I was unable to login.
I solved the ''issue'' by erasing the disk. My Macbook worked again, but all data was gone. The freezing issue was gone as well.
But 2 days ago, it started.. again. And today, my Macbook suddenly crashed/shut down. Now, I am not even able to start my macbook. It doesn't show anything, if I press the power button, nothing happens.
I did a SMC reset, and my Macbook worked, but only for 15 minutes. It just happened again. Something is clearly wrong and I don't know what.
Sometimes, my Macbook instanly freezed when I connected the power cord. And I think the power cord is broken, last few days it barely charged the Macbook.
Please help : (.
Stores close in 2 hours (9 PM), and I need to find a solution. What do I need to replace and buy?
**PLEASE HELP**

- The memory you are talking about, that's the same as RAM right?
Yes.
It's unclear whether you did anything with the memory or not, but even if you didn't, even a Mac's originally installed RAM could fail and cause the exact symptoms you describe. To test memory you can use Apple Hardware Test, though only a report of a failure can be considered definitive.
Also, I checked my magsafe, and the 2 power connectors are a little bit curved/bent. I am planning on buying a new Magsafe + new RAM (memory?). I think that will fix it?
I don't know, but it's not a good idea to use a power adapter or a MagSafe connector that you know is damaged.
For a definitive diagnosis it would be best to take your Mac to an Apple Store for evaluation. Schedule an appointment. Bring your power adapter. Even if you have to purchase a new power adapter there, the price isn't very different than you are likely to find anywhere else. Counterfeit, non-Apple power adapters can be hazardous to you, your Mac, your property, or all three, so buy it from Apple.
Memory on the other hand is another story. You can purchase RAM guaranteed to work from one of two vendors known to support Macs - Crucial or OWC / MacSales - much cheaper than from Apple.

Hi! My MacBook Pro won't start! HELP !!!

Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
Has anyone had this same problem?
All I get is white screen + grey Apple and spinning grey disk... it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
This MBP is from 2011, runs on OS X 10.6.8
I tried booting with OS X Snow Leopard CD, it didn't work! (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
When i run coomand on root# fsck -fy --> RESULT = my HD was checked and seems to be FINE!
Thanks

Please make a Genius Appointment and take it in for service.

My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

The folder with the question mark indicates that the machine is unable to find a bootable volume on startup. This is typically caused by one of three things:
1.) The internal HD has failed or is failing and needs to be replaced
2.) There is significant directory damage to the volume that requires repairing in order to boot
3.) Some other internal component failure between the HD and logic board
I'd ranked them in the order that is most common (from my personal experience). Boot to the OS X Recovery tool and attempt to repair the startup volume. If that fails or the drive is not detected it's usually a tell tale sign of a failed HD.

Installed Yosemite...now my MacBook pro won't start up. Keep showing "Kernel Panic!" HELP!

installed Yosemite and now my MacBook pro won't start up. Keeps showing "kernel panic"
PLEASE HELP ME!

If you can't start up and log in in the usual way, try in safe mode.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally 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.
Log in as an administrator to carry out these instructions. If you have only one account, you are the administrator.
☞ If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
Safe mode is slower than normal, and some things won’t work at all.
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 start in safe mode.
If you're able to log in, launch the Console 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 Console in the icon grid.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.

Reinstall OS X:
Reinstall Snow Leopard 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/.
Reinstalling Lion Without Erasing the Drive
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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

I was messing around with .kext files in the MacintoshHD and now my MacBook Pro won't start up.

I was messing around with .kext files in the MacintoshHD and moved the system.kext and two others to my desktop and deleted the originals and now the MacBook Pro won't start up. All I get at start up is the apple icon then a bunch of text shows up part of which says Mac OS version: not yet set. then the apple icon turns into the power icon and tells me to turn off the computer. I've tried reinstalling from the install DVD by holding down option when powering on and selecting the install DVD and it just goes to a white screen with the apple icon and stays like that. I didn't have the disk utility on my Mac before this happened because I deleted it to make room on my computer a while ago so I'm not sure if that's why it won't load the install DVD but anyone who knows the solution to this with out going to get it repaired would be greatly appreciated. Thank you!

Never mind my dad just found the original install DVD and that worked. Before I was using an install disc that Apple sent me for another issue I was having, but thanks for replying so quickly and trying to help on this Thanksgiving day!!!

MacBook Pro won't start after changing access rights

I did something very wrong. Unfortunately I changed the access rights of Macintosh HD for "everyone" to none.
Result, my MacBook Pro won't start anymore.
Already tried the installation disk, reset password for root and users. No result.
Help program "check acces rigths". Didn't work either.
How do I reset the access rights of Macintosh HD?

Macbook Pro won't start properly... keeps restarting without chime!

Macbook Pro won't start properly... keeps restarting without chime!
Late 2007 Macbook pro. OS upgrade worked great for me.
I have had this problem on and off for a month or so. I simply cannot figure out what the issue is. I have tried poerup with and without AC power and with/without battery installed.
Starting in Safe mode does not help.
Trying to start with a disk does not help.
It sort of seems like it might be an internal power issue or GPU issue.
It also feels sort of like a software compatibility issue since my Macbook Pro gets reallly slugish for no apparent reason sometimes and IU have to restart.
I have three different anti-virus programs so I doubt it is a virus issue.
I noticed all this start after I did a Mountain Lion upgrade and then tried to start up VMware Fusion. Fusion seemed to just bog down the computer horribly but did not cause a system crash.
I need to edit an important sequence on Final Cut Pro and don't want it to freeze me out!
Anyone who has had this problem and resolved it please let me know
God bless

17" Macbook Pro won't start at all. I shut it down last night at 80% and now there is only black screen, no light, no sound. What to do?

My 17" Macbook Pro won't start at all. I shut it down last night at 80% and today I get only a black screen with no sound, no light, nothing. The power cord light does show orange when plugged in. I don't know exactly which OS it is. It's model # A1286. I've tried all the tips about holding down different keys to no avail. Anyother ideas? (The serial # is w8******agu if that helps.) Many thanks.
<Edited By Host>

I had the exact same issue... Macbook Pro late 2008 with Core2Duo. Went to all the steps suggested in the knowledge base, tried to reset the SMC, but to no avail. Took it to the Macstore in Mexico, the wanted to replace logic board for $800.... Finally, I sent it to a logic board repair service, where they "fixed" the logic board for $200. It worked perfectly for 4 months, then happened again
Any ideas?? I would appreciate any help!!!!!
