Researching your laptop in my area, you can get $250 for that computer on Craigslist. That will take some patience though and it will need to be in great condition. Depending on where you are at in the world will determine how much you can ask for it. The electronics market is different from state to state, city to city. I would think something like that should sell fairly quickly for $200 anywhere.
Realistically, that is a good computer. Can you find another use for it? $200 doesn't seem like that much to let it go for. Maybe it could be re-purposed? I hate having to sell things for far less than their actual value just because the market doesn't support it.
