I just checked out your laptop online, its pretty ancient, from about 2003. I assume its not got a large HDD and about 512meg ram at the most right? You wont get a lot at all for a laptop like yours Im afraid, I wouldnt pay a lot for it anyway. I wouldnt pay more then $100 to be completely honest.
Btw we have a computer section you should have posted this in, you wont get many serious answers in the EOF. And next time you post something like this include proper stats on the laptop, and make a better title also.
edit: and dont listen to science, keep on smoking man!
