You might need to ship a laptop computer, and because it's an expensive item, you don't want it to get damaged in the mail. Knowing how to ship a laptop also saves you from negative feedback from buyers on any auction sites you use if you are selling it.
Find the box the laptop came in when you bought it. If this isn't available or if it's in poor condition, you'll need a proper box. Most major delivery services have a specific flat box designed for shipping laptops. Laptop mailers are a little more money than what you will pay at the post office. However, they come complete with special foam inserts and a separate compartment for the AC adapter.
Protect the computer. Make a sleeve out of bubble wrap. You can do this by taping bubble wrap around your computer. You can even leave an extra flap so the person receiving the laptop can easily slide it out. Once you place the laptop in the box, fill the remaining space with packing peanuts so the computer doesn't jostle during shipping.
Place the AC adapter beside the laptop, not on top of it. This will help ensure that the adapter doesn't damage the laptop during shipping.
Tape the box using packing tape. You can get clear plastic packing tape at any dollar store. A more durable tape is gummed paper tape with fiberglass yarns embedded in the paper. If you are using an old box, tape along every seam as an added protective measure.
Print the shipping address on a self-adhesive label. This will ensure that the postal carrier can read the address correctly. If you prefer to write the label by hand, print it clearly so it is legible. Remember to include your return address so the postal office can get the package back to you if there are any problems with the shipment.
Use insurance and delivery confirmation. This will add to the cost of shipping, but it will be worth it if there are any problems with the delivery. The cost of insurance depends on the value of the laptop. You can also purchase the ability to track your item online and have delivery confirmation. This is important if you are shipping your laptop to someone you don't know. This way, you will know exactly when the person received the laptop.
