    Release the power button, replace the battery, plug the computer back in and turn the computer on to see if the issue is resolved. On portables with batteries you can't remove, shut down the computer and plug in the MagSafe adapter. Press and release the "Shift-Control-Option" keys along with the power button simultaneously, release and then start your computer. Sometimes your Mac may lose track of the location of the startup disk. This can happen when you force your computer to shut down using the power button, or when a newly installed application wreaks havoc with your system. You can manually select the startup disk by holding down the "Option" key while the computer boots.

    Once inside the Disk Utility, click the "First Aid" tab, select your disk and then click the "Repair" button. If your operating system is badly corrupted, reinstalling it may be the only option. If Disk Utility advises you of a failing hard disk, you should immediately back up as much data as possible and install a new hard drive if possible.

    Otherwise, you can hold down the "C" key while the computer starts and select the option to "Reinstall OS X" and follow the prompts to reinstall your operating system. The process of reinstalling your operating system deletes everything, so make sure you back up as much data as you can. It may vary slightly or significantly with other versions or products.
