You'd be lucky if you got fifty bucks, if that, for that 2004 model year 700m laptop. Mostly, it's pretty much worthless. It's unlikely to adequately run any modern OS or applications well and it certainly won't play any modern games, pretty much at all.
About all I'd do with a unit like that is install XP or a very stripped down version of Windows 7, and install an office program on it, then sell it solely for use as a basic homework or office report type setup, or possibly as a learning tool for kids, for about 25-50 bucks. If that.
Considering you can get brand new, modern laptops, albeit stripped down lower capability ones, but still probably 50 times the capabilty of that unit, for less than 200 bucks these days, doesn't help to make those older systems worth much. Might be worth more to just keep as a basic internet browsing machine using XP in case something ever happens to your primary machine, and if this IS your primary machine, might be time to seriously look at getting something newer.
