Inspiron 1545 Beep Code

I have run the diagnostic on my Dell 1545 laptop.  I get the following message: DST Short Test FAIL 2000-0146.  I also get the following beep code: 1 Beep followed by 4 beeps followed by 6 beeps.  I would really love to understand the beep system.

Thank you for taking the time to read and respond to this question.
