hp dv7 will not boot up. Caps lock light blinks. Confused.

Computer help Forum and Discussion - CNET Forums - forums.cnet.com
I have an HP Pavilion dv7 4270us. The computer sounds like it is going to boot up and just goes to a black screen. The caps lock blinks once every 3-4 seconds. I looked up the blink codes but don't understand what they mean. For example blink code 1 (CPU problem). But it doesn't say what they mean by blink code 1. Does that mean one blink every second? Is blink code 3 once every 3 seconds?
