Computer Problems
The computer fails the POST
The computer POST (Power On Self Test) ensures that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST, the computer continues to start normally. However, if the computer fails the POST, the computer emits a series of beeps during start‑up. The following repetitive beep codes help you troubleshoot problems with your computer.
For assistance, contact Alienware (see “CONTACTING ALIENWARE“ on page 66).
NOTE: To replace parts, see the Service Manual at support.dell.com/manuals.
