Sell a laptop on eBay, what do I have to consider?

I sell my used laptop (about 1 year old) on ebay.

I'm a private dealer and the original price was 500 euro.

Although I often sell on eBay but never something so expensive. Do I have to pay attention to something?

Remember that you also note any defects. In addition, be sure to ship insured. Also you will pay a hefty fee to eBay, so wait until there are offers that lower the commission from eBay.
