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.

Macbook pro won't turn on. Flashing charger light. Please

I have had my macbook pro for less than a month and it will not turn on. When i plug in the charger it does one of 3 things; A) the little light on the charger won't turn on. B) it comes on orange and then after a period of a couple of minutes slowly fades out and then back on as green followed by flashing green. or C) It simply won't come on. The computer will not turn on during any of these instances. And when I check the battery by pressing the button on the side none of the 5 lights turn on.
I have tried it with the charger for my other macbook and still doesn't work. And both the chargers work on that computer. So i know it is an issue with the macbook itself.
The sleeper light never turns on at all either. I hope the battery didn't burn out.
Is there anybody out there who could please help me?
Shed some light on this...

Since you've had this for such a short time, I would take it to the Apple store and let them deal with it.
Do a back up first!

SOS help please. Macbook Pro won't turn on. Blinking Light

Hello to everyone this is my first post here and sadly its about a problem with my macbook pro.
The notebook in question is a 17'' Macbook Pro I bought in September 2008.
I simply closed it (without turning it off, just let it go on sleep) and took it with me as usual and when I tried turning it on again, it would not turn on.
I press the power button and I hear the hard drive/superdrive (not sure which of the two) start up and I see the sleep light turn on but after a few seconds its turns off again. If I hold the power button down for a few seconds the sleep light starts blinking and then the notebook turns off once more. In all cases the screen is black.
I tried everything here http://support.apple.com/kb/TS1365 and tried removing and re-installing the RAM and nothing changed.
Short of trying to re-install the RAM again I have no idea what to do. I won't be able to visit a Genius until after the 5th so any ideas/suggestions?

see http://support.apple.com/kb/HT2674 and http://support.apple.com/kb/HT2341 for some information about beeps and flashes.
In your case, though, jinnes, the slow blinks suggest that the computer is simply refusing to wake up from sleep.
One possible, though unusual, cause of this can be if you are using the computer with it stacked on top of a macbook. In this case the magnet in the macbook underneath activates the Hall effect switch in the MBP, making the latter think the lid is closed, and preventing wakeup. I've had this happen to me and it is quite unnerving at the time! Simply moving the MBP will fix it. see http://support.apple.com/kb/TS2917
The same effect could be generated by proximity to other magnets.
It is also possible , if this is not your situation, that the hall effect switch in your MBP is actually defective. It may be worth trying simply opening and closing the lid a few times to see if you can get it to activate.
Cheers
Rod

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.

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.

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.

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

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.

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.
