Remove the screws securing the lower case

  • Before starting this procedure, you should disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide to disable Auto Boot.

  • If your MacBook is running Big Sur v11.1 or later, disabling Auto Boot may not work. You can proceed normally, but make sure to disconnect the battery as soon as you're inside.

  • Completely power off and unplug your MacBook before you start. Close the display and flip the entire laptop upside-down.

  • Use a P5 driver to remove the following screws:

  • Two 7.9 mm screws

  • Two 7.3 mm screws

  • Six 2.6 mm screws

  • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your MacBook.

拧下固定底壳的螺丝

在开始此过程之前，请先禁用 Mac 的自动启动功能。自动启动功能会让已经关闭的 Mac 在掀开上盖时自动开机。该功能可能会导致 Mac 在维修过程中突然启动。参照本指南关闭自动启动功能。

如果 MacBook 已更新至 macOS Big Sur 11.1 及更新版本的操作系统，上述的关闭步骤可能不会起效。可以继续进行维修，但在拆卸时注意首先断开电源与主板的连接即可。

开始之前，请完全关闭 MacBook 并拔下外接电源。合上显示屏，然后将整个笔记本电脑上下颠倒。

使用P5驱动器卸下以下螺丝：

两颗7.9毫米螺丝

两颗7.3毫米螺丝

六颗2.6毫米螺丝

在整个维修过程中，请跟踪记录每颗螺丝的位置，并确保在组装时拧入原本的位置，避免损坏MacBook。
