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. 

/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
      Identifier  "Intel Graphics"
 
     #Driver      "modesetting"
     #Option      "AccelMethod"     "glamor"
 
      Driver      "intel"
      Option      "AccelMethod"     "sna"

     #Option      "DRI"             "2"

     Option      "Backlight"       "intel_backlight" # use your backlight that works here

EndSection

Keyboard mapping

To avoid error messages appearing in the output of dmesg, add 

/etc/udev/hwdb.d/99-hp_g430_g4.hwdb
# HP ProBook 430 G4
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnHP:pnHPProBook430G4:pvr*
 KEYBOARD_KEY_f8=wlan                                   # Wireless HW switch button

PCIe error in dmesg output

Feb 21 16:09:01 laptop64 kernel: pcieport 0000:00:1d.0:    [ 0] Receiver Error         (First)

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
