I'm younger and need more sales info!

it is true that when you will buy a new laptop or computer in general you should compare and control a bit more than in other devices!! i think to judge a good laptop you should always look for things you can't see from an external view and so i meant about hardware quality!!So if the laptop is from a good brand normally the hardware should be ok..afterthat you can think about configuration and so processor(what kind,brand,clock..cache level),RAM memory(4-8 gb is good),disk space (i think from 120-500 gb can be ok) , graphic card (nvidia get force should be the best) , ports(hdmi,ho much usb,and so on..), an so multimedia as webcam integrated and so on.. so to judge if your laptop have a good price you can look in other auctions for th same brand and model and just compare..and also arrange a meeting to see if your laptop is in good condition as described or not much..becaus eif not i sugget you to not buy or really give him less money as you prevented!!good luck!

Well, since the buyer knows what he's buying, the only thing you can do is lookup similar laptops on auction sites to see how much they're going for second-hand. Depending on the exact spec, you'll want to emphasize the processor model and speed, how much RAM, harddisk capacity and if it sports a dedicated graphics card then definitely give that a few minutes of your time... Maybe you could post the spec or brand/model...

Oh that's difficult, because you can't really do this overnight. But moreover, it will always have something to do with the memory (RAM) and the space of your computer. What's it's motherboard brand and how long have you had it, and why are you selling it. Further, there would also be questions as to your video card and sound cards.
