Overall Status

Legend :
= OK ; Unsupported(No Driver) ; = Error (Couldn't get it working); [?] Unknown, Not Test ; [-] Not-applicable
= Configuration Required; = Only works with a non-free driver and or firmware

Important Note

• Installation tested with Jessie RC1 as per notice in guide for InstallingDebianOn/HP/EliteBook 840 G1

Configuration

Storage

• main disk bay is recognized as sda

• m2 slot for small SSD is recognized as sdb

• second m2 slot (unoccupied WWAN slot) was not yet tested

• SW RAID was set up, following Multi HDD/SSD Partition Scheme, SSDOptimization

Audio

• ordering of the recognized cards was reversed
• options for modprobe had to be prepared

/etc/modules.d/snd-hda-intel.conf

options snd-hda-intel id=PCH index=0
options snd-hda-intel id=HDMI index=1 

Touchpad

• with synclient the emulation of simple tap and 3rd button was enabled

synclient TapButton1=1
synclient TapButton3=2

• double tapping on the LED to (un)lock the touchpad is apparently only possible by patching the kernel ¹, ², ³

Power Management

• installed TLP from sid repositories
• acpitool (and entities in /sys) functioning ok

• collection of battery stats was done following 720338

WiFi

• wireless button should work with hp_wireless module loaded, LED seems not to show real status

• firmware-iwlwifi was installed

Bluetooth

• Works if firmware-iwlwifi is installed

Volume

• the fn+f8 (microphone mute) does not generate any ACPI or keyboard event, LED is always on
• volume and mute generate ACPI events

/etc/acpi/actions/hp_volume.sh

        amixer set Master 5+
        ;;
    down)
