Apple MacBook Pro 15-inch

Resetting the System Management Controller (SMC)
To reset power management via the SMC chip:
1. If the computer is on, turn it off by choosing Shutdown from the Apple  menu.
2. Connect the power adapter to the computer and to a working power source.
3. Important: Use the keys on the left side of the keyboard. On the built-in keyboard, press Shift-Control-Option along with the power button once.
Note: When the LED on the MagSafe connector is orange, resetting the SMC will change it to green for a few seconds, indicating that SMC was correctly reset.
4. Wait 5 seconds and press the power button to restart the computer. Note: If bottom case is removed, you may alternately reset the SMC by disconnecting the power adapter and the main battery, and holding the power button down for five seconds.
Resetting the Parameter RAM (PRAM)
To reset PRAM,
1. If the computer is on, turn it off.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in Step 4.
Note: If the keyboard does not have an Option key, use the Alt key instead.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. Important: You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Starting Up in Safe Mode
A Safe Boot is a special way to start Mac OS X when troubleshooting. To start up into Safe Mode
(Safe Boot),
1. Make sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key.
Note: The Shift key should be held as soon as possible after the startup tone but not
before.
4. Release the Shift key when you see the screen with the gray Apple and progress indicator (looks like a spinning gear). During startup, ”Safe Boot” appears on the Mac OS X startup screen. To leave Safe Mode, restart the computer normally, without holding down any keys during startup.

Reinstalling Software That Came with the Computer
Use the software install discs that came with the computer to reinstall Mac OS X and any applications that came with the computer. Choose either “Archive and Install,” which saves the existing files and settings, or “Erase and Install,” which erases all the data.
Important: Apple recommends backing up data on the hard disk before restoring software. Because the “Erase and Install” option erases the hard disk, you should back up essential files before installing Mac OS X and other applications. Apple is not responsible for any lost data.

5. Follow the onscreen instructions.
Note: To restore Mac OS X on the computer to the original factory settings, click Options in the “Select a Destination” pane of the Installer, and then select “Erase and Install.” If you choose “Erase and Install,” you will see a message reminding you to use the Applications Install DVD to reinstall the bundled applications that came with the computer.
6. Whent the installation is complete, click Restart.
7. Follow the prompts in the Setup Assistant to set up the user account.
Installing Applications
If you reinstall Mac OS X on the computer and select the “Erase and Install” option, you must reinstall the applications that came with the computer, such as the iLife applications.
To install applications that came with the computer, follow these steps:
1. Make sure power adapter is connected and plugged in.
