Do your hear that beep sound every time to start the system (even when the system starts normally) or do your hear that beep sound only when there is no display (or no lights on the keyboard or mouse)? Yes, I hear the single beep every time the system starts. Additionally, when the system does boot up to Windows, it bypasses the normal Dell Startup Screen that allows you to enter the BIOS (F2) or change the boot order (F12). I tried to re-install the BIOS, but since I have the most current BIOS already installed, the BIOS re-installation fails.
Is your system covered under warranty? The system is not covered under a warranty.
