武汉苹果APPLE私货水货港行2013版 MacBook Air 13拆机教程及测评

武汉苹果APPLE私货水货港行2013版 MacBook Air 13拆机教程及测评,ifixit已经对2013版最新的MACPRO AIR 13动手了,下面来看下具体拆机过程和测评。
[color=#363636][font=微软雅黑]iFixit 这么快就已经拆解了才刚刚公布的 2013 年版 13 吋 MacBook Air。这款 MBA 的屏幕和外观都基本上没有变,只是在机身的左边转用双麦克风,Apple 在 WWDC 2013 上的一些宣传重点也只是改配 Intel Haswell 处理器、更快的 SSD 和更强的续航力,所以跟预期一样,iFixit 在这代的 MBA 上发现它配备了更大的电池 7,150mAh 电池,而上一代 2012 年中版则是 6,700mAh;前者是 7.6v,后者是 7.3v。另外,还有使用 PCI Express 界面的 SSD,以目测而言,每片 SSD 面积小了三分一左右。最后一个重点就是 Broadcom 制这的 802.11ac Wi-Fi 芯片。下面我们一起看一下ifixit的拆解原文吧:[/font][/color]              [hr]

[/size][list][*]Externally, the 2013 MacBook Air is nearly identical to its predecessor, including the model number (A1466).[*]The right side ports haven't changed a bit, with the new MacBook sporting the same lineup of SD card reader, USB 3.0, and Thunderbolt port.[*]A 180° rotation gives us a glimpse of the only noticeable change to the outer case: two ports for the dual microphones along the left side.[/list]

[list][*]We heard all the new stuff was [i]inside the computer[/i], so we grabbed our unfortunately necessaryPentalobe bit to open 'er up.[*]As we've come to expect by now, MacBooks of all shape and size are easy to open with the appropriate tools at hand.[/list]

[list][*]We can spot the differences between the 2012 (left) and 2013 (right) MacBook Airs, but can you? Let's see if you see what we see.
Smaller SSD module[*]Updated AirPort card[*]No separate platform controller hub[*]New heat sink clamp[*]Opposite-facing speaker cable connector[/list]
We could nitpick the differences between the two models all day, but we'd rather get back to disassembling the new guy.

[list][*]When we want to fast-forward through battery removal we go double time on our screw removal.
[i]iFixit fun fact:[/i] All iFixit guide makers must be ambidextrous enough to simultaneously use two screwdrivers.The 7.6 V, 7150 mAh battery inside this year's Air is an upgrade from the 2012's 7.3 V, 6700 mAh power source and contributes to the claimed 12-hour battery life.Increased capacity isn't the only addition to the new battery—important information is now printed in[s]Chinese[/s] Korean as well as English.[/list]

[list][*]In order to achieve flash storage that's "up to 45 percent faster" than the previous model, Apple switched from SATA to PCIe, and turned to its best pal in the industry: Samsung.[*]In this case we find:
Samsung S4LN053X01-8030 (ARM) flash controller[*]8 x Samsung K9LDGY8SIC-XCK0 16 GB flash storage[*]Samsung K4P2G324ED 512 MB RAM (the same RAM used in the Raspberry Pi)[/list]
We didn't run any tests to verify that thePCIe-based Samsung SSD is indeed that much faster than last year's Toshiba SATA module, but we can definitely say that the drive is smaller and not compatible with previous MacBook Air models, making it harder to find parts if you want to upgrade.

[list][*]What's that sound? Oh, it's just the MacBook Air's stereo speakers.[*]Other than the aforementioned change in the direction of one of the speaker cables, these appear to be the same speakers found in last year's model.[*]Some computer and smartphone manufacturers like to emphasize an industry partner's audio systems in their marketing. Apple is not one of those companies, simply listing the noisemakers in the MacBook Air as "stereo speakers."[/list]

[/size][list][*]The I/O board in the MacBook Air is mostly unchanged from last year, except that it no longer has a socket for the iSight cable.[*]We find a Cirrus chip marked 4208-CRZ next to the headphone jack. This is either an audio controller of some kind or a very small Chrysler.[/list]

[list][*]Goodnight logic board.[*]Goodnight heat sink.[*]Intel's fourth generation Core i5 processor appears to integrate the platform controller hub (PCH) right next to the CPU, a departure from the prior design's segregated chips.[*]The new heat sink design allows it to cover both chips, but Apple only put thermal compound on the CPU.
We won't complain too much though, as the old design left the PCH out in the hot with only the lower case as a heat sink.[/list]

[list][*]As in most other unibody MacBooks, the Air's trackpad is held to the upper case with six tiny Phillips screws and comes out without much hassle.[*]In addition to a plethora of connectors, we find the following chips on the trackpad board:
STMicroelectronics STM32F103VBmicrocontroller[*]MXIC MX25L2006E 2 Mb serial flash[*]Broadcom BCM5976A0KUB2G trackpad controller[/list]
Finally, we free the display assembly from the upper case by removing the Phillips screws that secure the two hinges.

[list][*]MacBook Air 13" Mid 2013 Repairability Score: [b]4 out of 10[/b] (10 is easiest to repair).
Once you manage to take off the bottom cover, all the parts are pretty easily replaceable.[*]Proprietary screws on the case require the right screwdriver.[*]All the components—including RAM and SSD—are proprietary.[*]As with the prior iterations, this MacBook Air's biggest detractor is the lack of upgradeability. The RAM is still soldered to the logic board, and SSDs are not compatible between generations.[/list]
