Installation
Secure Boot
must be disabled in the BIOS.
The BIOS can be accessed by holding down
Esc
while booting, then pressing
F10
when the options screen is shown.
F9
can be used to select the boot device.
Firmware
fwupd
supports this device.
Biometrics
Fingerprint Scanner
Tested using
Fprint
, fprintd-enroll reports that the device cannot be found.
Windows Hello
Facial recognition works using
Howdy
.
Audio
If audio does not work initially, create the file
/etc/modprobe.d/alsa-base.conf
with the following line.
options snd-hda-intel
The audio mute button works by default but with no led indicator to show its state.
Suggested fixes including adding
model=hp-gpio-led
after
snd-hda-intel
but this does not appear to work for this model.
Power management
For general battery improvements,
thermald
and
auto-cpufreq
AUR
seem to help,
although battery life is still poor.
Unfortunately HP do not support s3 sleep (see
Power management/Suspend and hibernate
) for this laptop,
which leads to extreme battery drain when left in 'suspend' mode (s2idle).
This can be fixed by modifying the
DSDT
, but resuming from suspend with deep sleep is unreliable, rendering this method pointless.
An alternative solution to saving power would be using
hibernation
and then focusing on
improving the boot time
to bring wakeup from hibernation closer to wakeup from suspend times.
ACPI override to support S3 sleep
This article or section needs expansion.
Reason:
Resuming from suspend with this method is unreliable and will usually leave you needing to reboot. The methods outlined in
Power management/Suspend and hibernate#Troubleshooting
do not seem to solve this. If you find a solution please update this page. (Discuss in
Talk:HP Spectre x360 15-df1010na
)
See
Power management/Suspend and hibernate#Changing suspend method
for the general context in which this workaround fits.
Extract and disassemble the
DSDT
tables. You then need to modify the
dsdt.dsl
file.
Find the section which begins with
DefinitionBlock ("", "DSDT", 2, "HPQOEM", "863E    ",
and increment the final number (remember to increment it as hex).
For example:
DefinitionBlock ("", "DSDT", 2, "HPQOEM", "863E    ", 0x01072009)
Should be changed to
DefinitionBlock ("", "DSDT", 2, "HPQOEM", "863E    ", 0x0107200a)
Then the definition for
S3 System State
needs to be added between the sections for
// _S0_: S0 System State
and
// _S4_: S4 System State
.
This should end up as follows:
Name (_S0, Package (0x04)  // _S0_: S0 System State
    {
        Zero, 
        Zero, 
        Zero, 
        Zero
    })
    Name (_S3, Package(0x04) //  _S3_: S3 System State
    {
        0x03,
        0x03,
        Zero,
        Zero
    })
    Name (_S4, Package (0x04)  // _S4_: S4 System State
    {
        0x06, 
        Zero, 
        Zero, 
        Zero
    })
You then need to recompile the DSDT tables and create a cpio override archive, as explained in
DSDT#Using modified code
.
