The HP Elitebook 850 G3 is a business grade workstation laptop released in 2017, the laptop is very durable and the ecosystem of HP devices are a well fit for a neat portable system. Most of the internal parts are cross compatible with the generation 4 (G4) Elitebooks and can easily be upgraded and be swapped in and out for wanted/remove unwanted features.
Firmware
This article or section needs expansion.
Reason:
Should cover if
fwupd
supports this device or not. (Discuss in
Talk:HP EliteBook 850 G3
)
UEFI / Secure Boot
Secure Boot
and TPM backed disk encryption is tested and works. Enrolling custom keys for secure boot is supported but is not tested, proceed with caution.
Configuration
AMD Graphics
The AMD Radeon R7 M365X is supported by both
radeon
and AMDGPU drivers, but
AMDGPU
driver performs better.
Fan control
Warning
Without configuring software the fan speed will sit at its lowest speed setting and thermal shutdowns are frequent. It is important that it is configured before any heavy load is put on the system.
Fan control requires additional software to be configured. Install
nbfc-linux
AUR
read
Fan speed control
for more information.
# nbfc config -s "HP EliteBook 850 G3"
Cellular
NetworkManager
uses
ModemManager
for mobile broadband connection support.
Setting up
usb_modeswitch
does not set up the modem properly. Add the following udev rule & script to manually configure the modem to operational mode,
/etc/udev/rules.d/99-hp-modem.rules
ACTION=="add", ATTR{idVendor}=="03f0", ATTR{idProduct}=="9d1d", RUN+="/usr/local/bin/hp-modem-setup.sh"
/usr/local/bin/hp-modem-setup.sh
#!/bin/bash

echo 0 > /sys/bus/usb/devices/1-3/bConfigurationValue
echo 2 > /sys/bus/usb/devices/1-3/bConfigurationValue
echo 1 > /sys/bus/usb/devices/1-3/bConfigurationValue
echo 3 > /sys/bus/usb/devices/1-3/bConfigurationValue
Give
executable
permissions to the modem set up script,
reload udev
and trigger an usb even to set up the device:
# udevadm trigger --action=add /sys/bus/usb/devices/1-3
Confirm that the modem is set up by running:
$ mmcli -L
Touchpad
To enable synaptics intertouch on Synaptics TM3140-001 for a better touch pad experience:
# modprobe -r psmouse
# modprobe psmouse synaptics_intertouch=1
If all works well you can make the changes persistent in next boot by adding the driver parameter to
Kernel parameters
.
Tips and tricks
Battery
Setting charging thresholds on the fly is unsupported. HP Intelligent charging can be used on windows to change battery health configurations on the fly while powered on. However battery health configurations (Maximize for Duration/Health, Let HP Manage..) could be set in the firmware setup. Maybe a UEFI variable + reboot mechanism of some sort can be developed as a workaround.
HP Docking
The docking port on the right side of the device below the sim card slot is and older docking standard that is now discontinued. To recognize whether the device is docked or not the path to the device can be found out by running:
$ find /sys/devices/platform -name dock -print -exec cat {} \;
A list of tested docks are listed,
Dock
Working?
HP UltraSlim Docking Station (B9C87AA#ABA)
Yes
Systemd + Udev
Below commands guides on how to setup docked and mobile
targets
with
udev
on a systemd configured system to aid with other tasks in the system. This can flexibly be used to for example mount file systems when docked or de/activate other systemd units that match the device profile when docked / mobile.
/etc/systemd/system/docked.target
[Unit]
Description=Laptop Docked Target
/etc/systemd/system/mobile.target
[Unit]
Description=Laptop Mobile Target
/etc/udev/rules.d/99-dock-detect.rules
# trigger an action(a) when the SMSC USB5534 hub in the dock is added

SUBSYSTEM=="usb", ACTION=="add",    ATTR{idVendor}=="0424", ATTR{idProduct}=="5434",      RUN+="/bin/systemctl start docked.target"
SUBSYSTEM=="usb", ACTION=="remove", DEVPATH=="/devices/pci0000:00/0000:00:14.0/usb2/2-4", RUN+="/bin/systemctl stop  docked.target"

SUBSYSTEM=="usb", ACTION=="add",    ATTR{idVendor}=="0424", ATTR{idProduct}=="5434",      RUN+="/bin/systemctl stop  mobile.target"
SUBSYSTEM=="usb", ACTION=="remove", DEVPATH=="/devices/pci0000:00/0000:00:14.0/usb2/2-4", RUN+="/bin/systemctl start mobile.target"
Here is an example use case where
hpfall
can be deactivated when the system is docked.
/etc/systemd/system/hpfall.service.d/docking.conf

Requires=mobile.target
BindsTo=mobile.target

WantedBy=multi-user.target mobile.target
HPFall (HP 3D DriveGaurd)
The laptop built to work with hard drives has an accelerometer to unload the drive head to prevent damage to the hard drive. If you have a harddrive the same feature is implemented by
hpfall
and is tested and works, follow the guide in
hpfall
to configure. The accelerometer can also be used for other purposes, values can be read using the jstest utility from the
joyutils
.
$ jstest /dev/input/js0
NFC
The NFC device on the board is unsupported by the NFC software/firmware stack.
Fingerprint
The fingerprint device "Validity Sensors, Inc. VFS495 Fingerprint Reader" does not work, as the firmware is proprietary and it's functionality is obscure to be integrated to the linux pam components. There are reverse engineered drivers that work with older kernels and older versions of libcrypto and other dependencies but later versions of packages seems to break commonly linked resources.
