Hi,
Our house got broken into last week and our laptop (purchased in early January 2011) was taken. On this occasion, we threw out the box and did not write down the serial number.
We still have the receipt with shows the date, time and purcharse information.
Would a retailer (JB Hi-Fi in our case) be able to supply us with the serial?
Did you register with the laptop company for warranty purposes? They should have the serial number
