have some one a good condition laptop weighing 1kg approx to sell immediately?

Answer 1

no do you have a 1 gb ram

Answer 2

How much did you pay for it? If you paid 1,000 dollars for I'd knock it down 500-600 dollars for it being used. Also how old is it? If it is not within the last couple of years you are going to have to knock off more money depending on age (If it is ten years old I'd say about 100-200 dollars). The reason I say this is because the technology is old and no one is going to pay 500-600 dollars for old technology.

What you paid for it
Age
Software
Hardware

This stuff should all be factored in when pricing your laptop for sale.
