设备信息

这是一份关于 HP ProBook 430 G4 的正在进行中的工作文档。这些型号的 HP Probook 有许多配置。以下信息来自型号为 HP ProBook 430 G4/822C，BIOS P85 Ver. 01.03 12/05/2016，配备 Core i5-7200U、8GB、256GB SSD 的型号。该笔记本电脑支持更换两个内存模块，并支持一个 2.5 英寸磁盘驱动器和一个 M.2-SSD。UEFI bios 允许传统启动。

德语评测请见此处：HP ProBook 430 G4 评测。基本硬件开箱即用。无需配置。“未测试”单元的信息将另行发布。

背光

到目前为止，我还没有找到通过内核硬件控制键通过内核控制背光的解决方案。因此，背光控制仅通过软件工作。它在 Xfce 下以及在使用自定义命令“xbacklight -inc/-dec 10”的 i3wm 下开箱即用。

ACPI 错误

内核 4.9.x 存在大量 acpi 相关错误消息

上游报告：https://bugzilla.kernel.org/show_bug.cgi?id=194833 - 这似乎是 BIOS 实现错误。

键盘映射

为避免错误消息出现在 dmesg 的输出中，请添加

/etc/udev/hwdb.d/99-hp_g430_g4.hwdb

# HP ProBook 430 G4

可以通过将 pci=noaer 附加到内核参数来修复此问题。

修复冷启动挂起

HP 笔记本电脑的 i2c_i801 模块实现中似乎存在一些错误。要修复冷启动时系统挂起的问题，请添加此模块加载选项并重新生成 initrds。

/etc/modprobe.d/i2c_i801.conf

# disable Host Notify + Interrupts
options i2c_i801 disable_features=0x30
