My Macbook pro won't turn On - Flashing Sleep Light
when I started my mac the screen is blank but the sleep light remains turn on.
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

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.

my macbook pro won't turn on without any reason, is there any solution in this case?
You need to hit the "reply" button on post to whom your responding too, it's hard to tell if your responding to me or someone else.
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.

Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Reinstalling Mavericks, Lion/Mountain 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.

Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
If you are not using Lion, Mountain Lion, or Mavericks then use the following procedure:

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.

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.
