Answers to Common Problems
System
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 99).
