Lithium-ion polymer battery

You might remember a couple months ago when our friends at iFixit tore down the new Retina MacBook Pro. Unfortunately, the device received its lowest repairability score with the company calling it “the least repairable laptop”. While the new MacBooks provide possibly Apple’s least accessible and upgradeable design out of the box, iFixit updated its website today with its official 2012 MacBook Pro Retina repair guide to make it as easy as possible. Fifteen separate installation guides for the AirPort Board, battery, fans, logic board, speakers, SSD, trackpad, etc., are included in the repair guide with one maintenance guide for reapplying thermal paste to the CPU and GPU.

Many components within the laptop can be removed without much fuss, provided folks use the correct tools. Pentalobe screws hold the lower case in place and Torx screws secure everything else. Spudgers and plastic opening tools are absolutely necessary, as many of the components are designed with such tight tolerances that using fingertips is simply not an option.

Fair warning: working on the laptop is no easy task. Some repairs are simply infeasible. For example, there is no way to replace the trackpad without removing the battery. And while it’s possible to remove the battery, chances are high that it will be punctured in the process. Puncturing Lithium-polymer batteries releases noxious fumes and can cause fires. Additionally, removing the LCD glass from the aluminum frame will almost certainly break the glass. So components residing under the LCD — such as the FaceTime camera — will have to be replaced with the entire assembly… Finding replacements for the machine’s proprietary components is currently difficult. We’re working to source parts, but it may take some time.

iFixit also estimated that third-party battery replacements —if done correctly— could cost over $500:

With all of the controversy and media attention Apple has experienced since The New York Times’  “How the U.S. Lost Out on iPhone Work” article, a post from Motherboard (via iFixit) provides yet another reason why Apple makes its products in China—rare earths. While noting China’s cheap labor and lack of environmental regulations certainly contribute to Apple’s decision, the post explained how Apple’s use of rare earth elements might make it hard to move manufacturing elsewhere:

But there’s another important reason why Apple and other manufacturers have their heels stuck in Chinese mud. iPad manufacturing, like the manufacturing of other electronics, requires a significant amount of rare earth elements, the 17 difficult-to-mine elements used in all kinds of green technology. It’s hard to say exactly what rare earths are in an iPad, since Apple is really tight-lipped about their materials

iFixit ‘s Elizabeth Chamberlain spoke with Cambridge engineering professor Dr. Tim Coombs who “guesses that there may be lanthanum in the iPad’s lithium-ion polymer battery, as well as ‘a range of rare earths to produce the different colours’ in the display.” He also thinks the magnets in Smart Covers and the iPad itself contain neodymium alloy. So how does rare earths keep Apple tied to China? The report explained:

We mentioned the iHelicopter back in August and it looked like one of the better iOS controlled flying devices out there.  Today, it got a significant update.

The $69.99 Cobra iHelicopters now get to go on the offensive.  The Cobra is armed with two missiles that can take out targets over 6 feet away.

The older version (without missiles)  can be found as low as $50
