: Shops use a grading system from "Mint" to "Poor". Cracked screens, missing keys, or heavy scuffs can devalue a laptop to near zero or lead to a rejection.

: Modern processors (Intel Core i5/i7 or AMD Ryzen) and at least 8GB to 16GB of RAM significantly increase value. Devices with SSD storage are also preferred over older hard drives.

: Having the original charger is vital; shops may deduct $20 to $40 if you don't have one because they must buy a replacement for resale. Original boxes and manuals can also slightly boost the offer.
