Buying used laptop

First, ask if there have been any major drops or anything traumatic like that. The reasoning is rather obvious there. Next, power each of them up and make sure that they aren't running overly hot, i.e. ensures that the fans are working. Finally, ask where it has been used, i.e. a lot of use on a flat surface like a desk or a lot of use on say, a rug. You'll want to hear on a flat, hard surface, as it helps to dispense with the heat. Any extended use on a surface that does not disperse heat well can lead to heat damage over time.

with 1gb memory, 40 to 60 gb hard disk, wireless, enough within that price range.
