Apple uses model number A1286 for the new MacBook Pro. Well, you have to find a new way to distinguish new ones from previous ones. Remove the cover. It should be noted that replacing the battery is not a trivial task, for this you will need a screwdriver. Under the hood, nothing surprising, everything is very similar to previous MacBook Pros. As usual, the warning sticker on the battery - do not remove the battery. Dumb sticker, you can't stop us! For some reason, Apple stopped using bolts with a 5-sided sprocket and replaced them with 3-sided ones. Apple, you can try as much as you want, we have all the screwdrivers here.
Battery capacity is now 77.5 W / h. Which is not so much more than the previous 73x W / h. In any case, this is clearly not enough to explain the extra 1-2 hours of work (according to Apple). One of the main changes of the new model is the Wi-Fi / Bluetooth board. Most of all, it resembles the MacBook Unibody. To disable the AirPort / Bluetooth module, you must first disconnect the antenna. Unscrew one bolt that holds the entire module. Two more bolts to separate the AirPort Express card module. The AirPort Express card itself is different from previous MacBook Pros. In fact, it is from the plastic version of the MacBook Unibody. Connectors in the photo, from left to right:
- Wi-Fi / Bluetooth antenna;
- Camera wire;
- Optical drive;
- Speaker connection;
By disconnecting the antenna, you can immediately pull out the optical drive. The new MacBook Pro has the same Seagate drives as before. Speakers and a subwoofer are fixed on 4 bolts. Apple has slightly redesigned the audio system. Now the speakers and the subwoofer are in separate acoustic spaces connected by keys. Since the AirPort / Bluetooth board is now closed in a metal box, Apple added an antenna, which is located in the cut frame for the laser discs. Indeed, a smart decision! After removing two coolers and disconnecting a bunch of connectors, you can remove the entire motherboard. The module of external ports and the second speaker has not changed.
Orange circled the NVIDIA GeForce GT 330M graphics chip. The operating system automatically switches to its use, if necessary.
Red marked Intel Core i5 with integrated graphics.
Yellow is the Intel BD82HM55 S LGZS Platform Controller Hub. An interesting fact is that it does not have a radiator, apparently switching graphics is not such a heat-intensive task. Intel BD82HM55 S LGZS Platform Controller Hub closer. As we understand it, this chip is a kind of switch between Intel and NVIDIA graphics. The process of disconnecting the radiator. And finally, all the insides of the laptop. In general, nothing particularly interesting in the new Core i5 for iFixit. Source: www.ifixit.com
