Device information

This is a work in progress with information about the HP ProBook 430 G4. There are many configurations for these models of HP Probooks. The information below are given from a model HP ProBook 430 G4/822C, BIOS P85 Ver. 01.03 12/05/2016, shipped with a Core i5-7200U, 8GB, 256GB SSD. The notebook supports exchanging two memory modules and support one 2,5" disc drive and one M.2-SSD. The UEFI bios allows legacy boot.

A review in German is available here: HP ProBook 430 G4 review. Basic hardware works out of the box. No configuration was needed. Information for the "Not tested" units will be posted additionally.

Backlight

I have not found a solution so far to control the backlight via kernel hardware control keys via kernel. So backlight control works only via software. It works out of the box under Xfce and under i3wm using a custom command "xbacklight -inc/-dec 10".

ACPI errors

There are lots of acpi related error messages with kernel 4.9.x:

Upstream report: https://bugzilla.kernel.org/show_bug.cgi?id=194833 - this seems to be a BIOS implementation bug.

Graphic card setup

Either modesetting driver or Intel driver seem to work well. Using the Intel driver with DRI3 works well.

Keyboard mapping

To avoid error messages appearing in the output of , add

PCIe error in dmesg output

This one can be fixed with appending pci=noaer to the kernel boot line.

Fix cold boot hang

There seems to be some bug in i2c_i801 module implementation with HP notebooks. To fix system hang at cold boot add this module loading options and regenerate initrds.

/etc/modprobe.d/i2c_i801.conf

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

gollark: Weird that even that is hard to get into I guess, although something something COVID-19 influence on the sector.

gollark: Oh.

gollark: What sort of places, I mean.

gollark: Applied to do what at which places?

gollark: I don't actually own any lasers except possibly for one in a DVD drive I don't use.
