A customer who returns a laptop or other electronic device to a retailer may, for benign or malign reasons, have changed its firmware. The retailer typically certifies the laptop for resale as refurbished equipment by sending it to the factory to verify its firmware. This is a time-consuming and expensive process. The techniques of this disclosure leverage an on-board security chip to verify the firmware at the location of the retailer itself. Shipping of the electronic device from retailer to factory is obviated, saving time and cost.
