四叶草Clover引导提取DSDT/SSDT以及DSDT注入亮度补丁-实现笔记本电脑的亮度调节滑动条


之前我也出过笔记本电脑亮度调节教程,就是这个两步实现笔记本电脑屏幕亮度调节方法但是部分的朋友按照操作后还是无法调节亮度,应群友的要求。本次给大家补充一下DSDT注入的方式去调节亮度,顺便提一下通过Clover提取DSDT/SSDT,之前在讲解通过Windows提取dsdt与ssdt修复电池电量,《笔记本电脑电池显示》很多人提取后,不知道是操作原因,还是什么问题,无法反编译,可以考虑通过Clover提取DSDT/SSDT在试一下。下面就开始吧。

所需软件下载

 

  MaciASL.app 26-26.png  下载地址: https://pan.baidu.com/s/1nZCJlNiMUofTiaEyNtZkpA
  提取件码:h2q1
  iasl 26-26.png  下载地址: https://pan.baidu.com/s/1ww9lLXcu06VrY3ZJ56Wfnw

本教程有视频教程请移步



Clover提取DSDT/SSDT

在四叶草Clover引导界面按F4(部分电脑需要按fn+F4),按完之后不会有任何的提示,如果硬盘慢的话会出现短暂的卡死状态,如果好点的硬盘是感觉不出来的,之后直接进入苹果系统,打开EFI引导分区,路径为:EFI/CLOVER/ACPI/origin.提取的dsdt与ssdt都在里面!把ssdt改名称为SSDT.aml、SSDT-1.aml、SSDT-2.aml……

反编译除错

1.桌面新建一个acpi文件,把DSDT/SSDT拷贝进去。
2.新建“访达”窗口——前往——前往文件夹——/usr/bin/,把iasl编译器拷贝进去
3.反编译,打开终端输入:cd Desktop/acpi回车
再输入iasl -da -dl *.aml回车
反编译成功得到文件的dsl文件
4.用MaciASL.app打开DSDT.aml,编译时注意用5.0以上编译器编译!
5.DSDT.aml打开后第一件事情不是直接修改,而是排除错误
6.点击编译,红色的是错误,要把它排除,黄色的是警告,警告请忽略!

我的DSDT打开后有两个错误(每个人的可能错误不一样,其他的自己百度找解决方案吧!如果有编程功底,这个除错应该不是难事情)

错误一 syntax error, unexpected PARSEOP_INTEGER
错误解决方案
找到错误上方 0x1F,在0x1F前面//注释就好
注释前0x1F
注释后// 0x1F

错误二syntax error, unexpected PARSEOP_ARG0
错误解决方案
找到错误行上方如下代码并注释
注释前
Arg0
Arg1
Arg2
Arg3
注释后如下
/*Arg0
Arg1
Arg2
Arg3*/

注入亮度补丁

我这里提供了4个补丁,大家可以按照你的机型配置去选择补丁,使用其中一个就好,如果你都不知道怎么选择,那就一个一个的试试吧,反正就4个也不多。其实这4个补丁都来源于一个叫“RehabMan Laptop”的补丁源。链接是http://raw.github.com/RehabMan/Laptop-DSDT-Patch/master,在这里我还是把它提取出来放了,因为怕你们打不开!你也可以直接把这个链接添加到补丁源里面!如下图

那下面我们就开始打补丁吧!
除错完成后,按照如图所示打补丁就好,打好之后点击close关闭,保存为DSDT.aml文件放到EFI/CLOVER/ACPI/patched。重新启动就好。
