如何健全地检查我的 ACPI 表？

  • 772

我认为笔记本电脑中可能存在与 ACPI 相关的固件错误。如何检查我的 ACPI 表是否正常？

    幸运的是，有可用的工具。

    fwts

    这是固件测试套件，旨在询问和查看 BIOS + ACPI 固件错误。在最新的开发版本中提供了几个测试。

    安装：

    快速检查Ubuntu 软件包表明我们必须首先启用 Universe 存储库（如果尚未启用）。

    然后我们通过软件中心或使用命令安装：

    sudo apt-get install fwts

    fwts 可以运行几个有用的测试。

    也许最常用的一项是测试背光、亮度和电池的交互式测试。这是使用以下命令启动的：

    sudo fwts --interactive

    结果如下。

    Running 6 tests, results appended to results.log
==== Please press the laptop power button. ====
==== Setting backlight to a low level ====
==== Is the Backlight now set to a dim level? [Y/N]: 
==== Setting backlight to highest level ====
==== Is the Backlight now set to a bright level? [Y/N]: 
==== Backlight will now slowly transition from dim to bright ====
==== Did the backlight go from dim to bright? [Y/N]: 
==== Press the brightness UP hotkey for acpi_video0 ====
==== Press the brightness DOWN hotkey for acpi_video0 ====
==== Make sure laptop is connected to the mains power. ====
Press <Enter> to continue
==== Please unplug the laptop power. ====
==== Please re-connect the laptop power. ====

    可以在文件 results.log 中启动 fwts 的目录中找到测试结果

    Acer Aspire D270-1865 的结果如下：

in the ACPI BIOS, and any warnings given by the ACPI interpreter will be
reported.

    另一种方法acpiexec来自acpica-tools 包。该软件包还要求我们 启用 Universe 存储库，以便通过软件中心或使用以下命令安装它：

    sudo apt-get install acpica-tools
