Some of our newer devices may come with several months to a couple of years of manufacture's warranty (AppleCare, Lenovo or HP). For any computers in our store with a manufacturer's warranty, it will not require a transfer of ownership because the warranty is tied to the serial number of the device. Anyone who has the device is covered.
You can use the manufacturer warranty at any time during its active period by giving the manufacturer a call to one of their support centers. No registration required.
