battery fully recharged but mac not starting up

My battery drained completely. I recharged it. The green light is on. I turn the computer on but all I'm getting is the spinning wheel and the apple logo.

Is there any way to fix this myself without having to bring it in for repair?

Thanks,

Christine

Here are three things to try before going to a repair shop.

(1) Repair the file system with fsck command.

(2) PRAM reset.

(3) SMC reset (someone suggested that above and perhaps you already tried it ...)


Restart your computer, you may need to hold the power button for 5-10 seconds to get it to shut down. Then restart and hold Command-S.


You should see a plain screen with some typewriter-like text scrolling down. When it stops scrolling, hit return once or twice. Then type the following (carefully):


fsck -fy


(That is the letters "fsck" followed by one space and then "-fy" all without the quotes.)


If it says something was fixed or repaired, repeat the above until it comes back with disk appears to be ok.


If it says that disk appears to be ok, try restarting again.


[If it says that it cannot fix the problems it finds, you may need to try a different utility such as DiskWarrior or Tech Tool Pro, either of which must be purchased (~$80) from the Apple Store, Best Buy etc.]


If it says the disk is ok but restarting still doesn't work, try resetting the PRAM.


How to reset PRAM:


Shut down your Mac.

Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously.

Turn on the computer.

Press and hold the Command-Option-P-R keys before the gray screen appears.

Hold the keys down until the computer restarts and you hear the startup sound for the second time.

Release the keys.


If this doesn't enable your Mac to start up, then try an SMC reset. This is sort of a last resort but I have seen it work!


Resetting the SMC on Mac portables with a battery you can remove

Shut down the computer.

Disconnect the MagSafe power adapter from the computer, if it's connected.

Remove the battery.

Press and hold the power button for 5 seconds.

Release the power button.

Reconnect the battery and MagSafe power adapter.

Press the power button to turn on the computer.



Resetting the SMC on portables with a battery you should not remove on your own

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

Shut down the computer.

Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

Release all the keys and the power button at the same time.

Press the power button to turn on the computer.

Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
