It carries all the components you need for the top half of the laptop — keyboard, battery, housing, etc. Key Features & Components OEM top case: Apple original part Includes backlit keyboard built into the upper case Integrated battery cells mounted to the housing Palm rest / palm area with matching finish Cutouts and mounts for trackpad, speakers, and internal cabling Compatible with A2338 MacBook Pro (2020 M1 / 2022 M2) models Requires transfer of the Touch ID sensor, as it’s paired to the logic board not included in the case May or may not include trackpad (depending on seller / condition) Tested for battery health, keyboard functionality, internal connections (unless otherwise stated) Detailed Specifications Important Notes & Caveats Must ensure exact model (A2338) — other top cases won’t match in ports, screw layout, and internal fit. Transfer the Touch ID / fingerprint sensor from your original case — it’s tied to the logic board. Check battery condition before listing / resale — internal cells may have wear. Minor cosmetic defects or marks may exist due to being a used part. Installation requires moderate repair skills — ribbon cables, screws, and internals must be aligned correctly.
