DV2000, power adaptor plugged in, no charge

Hello,
So, I'm working on my HP Pavilion dv2000 laptop, and suddenly the screen darkens. I check the power adapter, and the blue light that usually lights up when it's plugged in is mysteriously off, signifying that it isn't plugged in.

I check my power adapter. I plug and unplug every necessary part, but I'm still getting no charge. At first, I could maneuver the chord around and the blue light would flash...but now, not even that happens!

Is my power adapter busted? Or could it be something more serious?
