Quick Check Procedures Resetting the System Management Controller (SMC) The System Management Controller (SMC) is a chip on the logic board that controls all power functions. For more information, refer to Apple Support article: HT5860: Mac computers: About startup tones. A sequence of tones heard at startup or a no video symptom may also be fixed by temporarily removing/replacing the backup battery. If RAM fails POST again, remove all installed RAM and test by installing one by one each RAM module that has been verified to work correctly on another computer (i.e., “known-good” RAM) or order new RAM. The solution to both of these situations is to first re-seat RAM and test computer again. In this case, the computer will display a gray screen, sound three beeps and repeat beeps until computer is turned off. Some RAM may appear to pass POST, but still cannot be used by the operating system. This error condition may be due to physically damaged RAM, installing an incorrect type of RAM, or not having RAM installed. If the computer detects out-of-specification or no Random-Access Memory (RAM), the screen will remain black but the computer will beep.
IMac (2008 and later): Power-On Self-Test (POST) Intel-based Mac computers such as the iMac rely on a combination of tones and blinking LED lights to display Power-On Self-Test (POST) error codes.
