Thanks for the responses guys. I figured out from the battry it was a HP Pavilion N3290, came out in 2000 and sold for $2199 (wow!).
As far as it having no value, I think you guys should spend more time on ebay/craigslist
I sold mine today on CL for $40 (I was able to fix it up, it was able to boot up to xp. Could browse basic websites like this forum, ebay, CL with it. Youtube was a nono tho, bad stuttering) . Check out the sold listings for 500mhz pentium laptops; here's a prime example; it sold for $69.
