Troubleshooting dell inspiron 4150

My laptop will not boot past the windows logo.

We need more symptoms than that to help you out. When did it start? What OS? Etc...

I'm operating the i4150 with windows xp home edition. Since my last write in, I ran down the battery to the point where I could not boot up. Now when I plug in the ac adapter, which I checked and it has about 18V output, the light does not come on indicating that I have no power to the machine. What next?
