iFixit has released its MacBook Unibody Mid 2010 teardown. The MacBook Unibody Model A1342 Mid 2010 has a new battery, which has gained in rating, improving from 60Wh to a 63.5Wh rating, with no change in size, but a minimal increase in weight. Tri-wing screws are still used for securing the battery, to the dismay of iFixit engineers. The overall impression is one of little change in structure and design. The NVIDIA GeForce 320M integrated graphics (256MB sharedDDR3 SDRAM) is new, replacing the GeForce 9400M.
