Apple’s MacBook went under the knife last year and received a major makeover. This year, the laptop received much milder internal changes, most notably a better graphics processor and more battery life.
We delved inside the MacBook to find exactly how that additional battery juice was achieved, as well as to see if there were any magical unicorns that Apple chose to keep hidden from public view.
We also made a YouTube video slideshow for those who like moving pictures!
- The battery is identical in size and shape to the old one, but is rated for 63.5 Wh (compared to 60Wh) and weighs 355 g (compared to 347.5 g).
- The battery also works in the previous MacBook! You can get an extra 350 mAh of electric charge if you’re willing to add 7.5 grams to your older machine.
- Of course, Apple continues to use tri-wing screws for the battery, as well as the “Do not remove the battery” warning sticker. We ask: why is it such a big deal to have users replace it themselves?
- We confirmed the updated NVIDIA GeForce 320M integrated graphics, much to the thrill of lite gamers everywhere.
- No MacBooks were hurt, in any way, shape, or form, during the teardown process.
Removing the heat sink
We partnered with Chipworks to bring you a teardown of the all-new Microsoft Kin Two.
Kin Two’s most notable feature is the Nvidia Tegra processor, which Chipworks found buried beneath a Numonyx package that’s visible on the logic board.
Chipworks confirmed that it was indeed the Nvidia Tegra after a morning of taking x-rays and de-potting chips. Don’t worry kids, no animals were harmed in the process.
- The Kin Two is 19.05 mm thick. That makes for a bigger bulge in the pants, given that the iPhone and Motorola Droid are 12.3 mm and 13.7 mm thick, respectively. (Enter “Is that a Kin Two, or are you happy to see me?” jokes here.)
- The Kin Two has two very cool-looking (to a mechanical engineer) springs that keep the phone’s halves either fully-open or fully-closed.
- For being able to shoot all of 8 megapixels, the camera only eats up about .5 cm^3 of space.
- Samsung’s moviNAND KLM8G4DEDD package supplies the 8GB of storage space for the Kin. It features a very advanced thirty nanometer architecture, and can transfer data at speeds up to 52 MB/s.
- The camera is the Sony IMX046. The IMX046 is fabricated using a 90 nm CMOS process. The camera’s resolution is 8.11 effective megapixel (8 active megapixel), 1.4 μm sized pixel, 1/3.2″ optical format. Samsung was the first to use this camera in the M8800.
- Taking a cue from the iPhone and Zune HD, the Kin Two has an accelerometer. It’s an STMicro 331DL 3 Axis nano MEMS (microelectromechanical systems) device.

Today’s photos from Vietnam of a leaked iPhone 4G prototype contain legible part numbers revealing new iPhone’s processor: the Apple A4.
The silkscreen on the production A4 reads:
- APL0398 339S0084 YNL215X0
- K4X2G643GE N26CGM0T
The leaked prototype has these markings:
- APL0398 339S0084 YNE07423
- K4X2G643GE GSA1400A
The two numbers that are different are likely manufacturing numbers (each lot of chips is stamped with a unique number to track them through the supply chain). The important numbers are:
- APL0398 339S0084 <– Apple A4
- K4X2G643GE <– 256 MB Samsung DRAM (two dies)
Our engineers are not surprised by this finding. We were very impressed by the extraordinarily low power consumption of the iPad, and remarked at the time that its power consumption and board design was much more in line with handheld devices than laptop computers.
In conjunction with Chipworks, we have already reported heavily on the design of the A4. Our Apple A4 teardown goes into detail on how the A4 is constructed.
Chipworks has more information here:

Hey folks, here’s another great iFixit wallpaper for you to enjoy! We snapped a few photos of the iPad internals during the iPad Wi-Fi teardown and correctly cropped them so you could peer through the LCD in your iPad.
Predictably enough, we encountered one small problem after we put the wallpaper on our tablet: the iPad’s uncanny ability to rotate the display, including the wallpaper itself. During “quality assurance testing,” the portrait wallpaper didn’t look too appealing in landscape mode, and vice versa. But we realized that most iPad users keep it locked on a specific orientation most of the time, so we created both orientations to mitigate the problem.
So here are two iPad “internals” wallpapers, one for landscape mode and one for portrait mode.
How to set it as your wallpaper on your iPad:
- Click on the links above or pictures below to view the whole wallpaper.
- Long-press on the image to save it.
- Go to your images, find the right wallpaper image and click the options button in the top-right corner to set it as wallpaper.
This is how the iPad wallpapers look like when on the iPad itself:
