  1. In order to discard corrupt BIOS settings in Mobiles please follow these steps:
    1. Press and Hold the <FN> key down.
    2. Without releasing the <FN> key, Power "ON" the system.
    3. You will notice the computer will try to turn ON and after a few seconds will turn OFF and back ON automatically. At this point you can release the <FN> Key.
    4. If the computer starts displaying image it means that now is completing the POST. Load into Windows and Update the system BIOS to the latest Version available (Re-Flash it if you are using the latest version already).
    5. Then Run the Built In Hardware Diagnostics. Alienware™ Enhanced Systems Diagnostics (ePSA)
    6. If the system does not complete the POST, unplug the AC adapter and remove the Battery (Some models require you to remove the service cover). Drain all remaining power (Press and hold down the Power button for 20 seconds, the computer is not expected to turn ON), reinstall the battery and reconnect the AC adapter and repeat steps a, b, c, d.
    7. If your system is completing the POST test it out by turning it OFF/ON several times to assure the problem is being fixed.
    8. If still the computer is not completing the POST refer to the Failure codes table below.
