Hello !

I've installed Debian Stretch on my HP x2 Detachable with the kernel
4.19.

My battery isn't recognised, so I don't have a battery level in the
systray. Only the command `lshw` is able to identify the battery :

-battery
--- produit: SW02032XL
--- fabriquant: 333-42-1E-A
--- identifiant matériel: 1
--- emplacement: Primary
--- capacité: 32570mWh
--- configuration: voltage=7,7V

I've tried a lot of things without succes. It's seems like the kernel
isn't able to recognise the battery.

Do you have any tips about this problem?


Sylvain

Thanks a lot for your answers.

I realize that I didn't give you the pieces of information needed. Sorry.

My netbook is a "HP x2 detachable 10-p029NF". I'm under Debian Stretch,
kernel 4.19 (backports), and I use KDE.

There's a option in the bios that allows the OS to see the battery
status or not. But it seemes it doesn't work because the behavior of the
OS is the same if set on or off.


Thirst clue, the icone in the system tray tells "no batterie available".
--------------------------------
Second clue, the command "ls /sys/class/power_supply" doesn't show
"BAT0", but only "ADP1".
--------------------------------
Third clue, here's the result of the command upower -e:
--------------------------------
/org/freedesktop/UPower/devices/line_power_ADP1
/org/freedesktop/UPower/devices/DisplayDevice

Fourth clue, "acpi -V" gives me:
--------------------------------
Adapter 0: off-line
Thermal 0: ok, 53.0 degrees C
Thermal 0: trip point 0 switches to mode hot at temperature 89.0
degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 87.0
degrees C
Cooling 0: Processor 0 of 10
Cooling 1: PNIT no state information available
Cooling 2: soc_dts1 no state information available
Cooling 3: Processor 0 of 10
Cooling 4: STR0 no state information available
Cooling 5: Processor 0 of 10
Cooling 6: STR2 no state information available
Cooling 7: intel_powerclamp no state information available
Cooling 8: soc_dts0 no state information available
Cooling 9: Processor 0 of 10
Cooling 10: INT3400 Thermal no state information available

Fith clue, the "lshw" command finds the battery whatever the option in
the bios is set or not:
--------------------------------
-battery
--- produit: SW02032XL
--- fabriquant: 333-42-1E-A
--- identifiant matériel: 1
--- emplacement: Primary
--- capacité: 32570mWh
--- configuration: voltage=7,7V


I don't understand why only "lshw" can find the battery...
I think that there's a probleme between the BIOS and acpi.

Sylvain

I would suggest checking the product web page and
see if a BIOS update is available.

Contact Tech Support at HP and report your results.
While they might not have a very active BIOS development
process, they might pass your trouble ticket to the
BIOS development team and include it for consideration
for fixes before another BIOS is released.
