Thanks for the advice, yea im using a signed for and trackable service. Call me naive but, the money is in my bank account now so i have no worries regaring the payment. Or should there still be cause for concern?
Just had look at this guys previous purchases. Theres a lot of laptops and desktop pc's on there. hmm.
The selling site you used to sell ALWAYS favour the buyer, so if there is a problem with the laptop, they will always rule in favour with the buyer. They can chargeback the sum paid to your account. Many have left said site now.
Would you mind putting up a link to the sale so we can take a look at the buyer?
Surely he would have to return the laptop to me before i would have to refund im though right?
This is my first auction site sale, however i have since transferred the funds from paypal into my bank account successfully. Therefore i think he is verified.

You really undersold that laptop, hence the quick buy. I sold a 1545 for 180.00 last month, thats with Vista, 2gb and 160gb + a T3400 cpu (awful).
The guy probably buys up laptops and resells them, probably nothing to worry about. Theres one there thats not even working going so far for 50.00 with 21hrs to go.

, got a free T9800 cpu few months back and thought, why not? Bought it for about 150.00 from a mate, stuck a 120gb Vertex 2E and 4gb ram in it + 8800mah battery, performance is out of this world 
Surely he would have to return the laptop to me before i would have to refund im though right?
not always, there are lots of scams
what if he says he never received it, or that there was brick in the box instead of a laptop
then paypal would take back the money, and he would have a refund and your laptop
be careful
