Apple Silicon 版苹果 MacBook Pro 内置巧妙的省电机制，屏幕靠近键盘后，内置的屏幕开合角度传感器会让设备自动休眠。但这个小部件一旦发生故障，会引发类似主板报废的假象。IT之家附上视频如下：

该博主维修过程中发现一台“变砖”的 MacBook Pro，无论怎样敲击触控板或键盘，电脑都毫无反应，但只要接上 MagSafe 充电线并轻按电源键，屏幕就能点亮。

常规排查通常会判定电池损坏或主板接口故障，导致用户面临高昂维修费。该博主拆机后发现，设备内部缺失多颗螺丝，显然曾被其他人员拆解检查过，但未能查出病因。

幸运的是，该博主曾处理过类似故障，经过精准排查，确定真正元凶是开合角度传感器进水，系统因此误认为屏幕一直处于合盖状态，从而强制切断电池唤醒功能。

修复该故障极其简单，博主仅更换这个低成本零件，就让这台险些报废的电脑重获新生。他还表示如果维修时买不到替换零件，直接拆除坏掉的传感器也能彻底解决死机问题。
