Identification and Background

The MacBook Pro 15" Mid 2009 2.53 GHz Unibody was announced in September of 2009 as a low-end option in the 2009 15" MacBook Pro lineup. Unlike the rest of the 2009 15" MacBook Pro laptops, it does not include a dedicated graphics processor. Because of the lesser processing power, this model only has one fan, while other 15" MacBook Pro models feature two.

Use the laptop identification system to help you identify your machine. MacBooks tend to look very similar, and it's important to know which machine you have before ordering any replacement parts.

The MacBook Pro 15" Mid 2009 2.53 GHz Unibody's case is composed of aluminum, just like the laptops before it. However, the case is machined out of a single block of aluminum, following the same process of the MacBook Unibody A1278 and the MacBook Pro 15" Unibody Repair. The Unibody revision also introduced some features that were never before seen on an Apple laptop: the inclusion of dual video cards (one for regular use, one for graphics intensive applications) the Mini DisplayPort (which replaced the full-size DVI display connector), and larger hard drive and RAM capacities.
