The computer fails the POST
The POST (Power On Self Test) tests the computer, ensuring that it meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST, the computer will continue to start normally. However, if the computer fails the POST, the computer will generate a single beep to indicate a general failure and an error message will be displayed. For assistance, contact Alienware Technical Support (see “CONTACTING ALIENWARE“ on page 73).
