Default Battery not recognised

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?

I like the Arch Linux articles, for background info.

https://wiki.archlinux.org/index.php...#Battery_state

"ACPI

Battery state can be read using ACPI utilities from the terminal.

ACPI command line utilities are provided via the acpi package.

See ACPI modules for more information.

cbatticon is a battery icon that sits in the system tray.

batterymon-cloneAUR is a battery monitor that sits in the
system tray, similar to batti.

batifyAUR is an udevrule file triggering plug and battery level
notifications (multi-x sessions support).
"

It says there, that the ACPI subsystem provided by the BIOS
(ACPI tables), has an ACPI object representing the battery.
So the software in Linux to read it, will be dealing with
the ACPI object, rather than running a "serial interface" on
the battery directly.

*******

And this article

https://superuser.com/questions/8083...ly-bat0-uevent

suggests:

cat /sys/class/power_supply/BAT0/uevent

POWER_SUPPLY_NAME=BAT0
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CYCLE_COUNT=481
POWER_SUPPLY_VOLTAGE_MIN_DESIGN=7400000
POWER_SUPPLY_VOLTAGE_NOW=7400000
POWER_SUPPLY_POWER_NOW=9361000
POWER_SUPPLY_ENERGY_FULL_DESIGN=48248000
POWER_SUPPLY_ENERGY_FULL=40877000
POWER_SUPPLY_ENERGY_NOW=20712000
POWER_SUPPLY_CAPACITY=50
POWER_SUPPLY_MODEL_NAME=UX32-65
POWER_SUPPLY_MANUFACTURER=ASUSTeK
POWER_SUPPLY_SERIAL_NUMBER=

Maybe that will tell you if it is detected.

*******

If you have purchased a third-party battery, it's
possible the capacity monitoring chip is not set up
properly. And that's why it isn't registering properly.

This document seems to suggest it's on SMBUS (the same bus
that the SPD chip on the DIMMs use). While the word I2C
appears in the document in the definition section, the word
doesn't appear in the body text.

http://smartbattery.org/specs/sbdat110.pdf

And this is the smart battery charger, the "power management
block" on the motherboard. It charges the battery up, when
the battery is discharged slightly, and AC power is available.
This isn't likely to answer any of your questions, but is a
companion to the other spec.

http://sbs-forum.org/specs/sbc110.pdf

Pointer from here.

https://electronics.stackexchange.co...-battery-packs

*******

https://www.kernel.org/doc/html/v4.1...r-api/i2c.html

There is this. (With the usual "caution" language)

https://linux.die.net/man/8/i2cdetect

There is lm-sensors, but I can't see any evidence it sees
laptop battery chips as part of its feature set.

*******

It's possible some subsystem is missing between ACPI
and user-land. But what, I don't know... Is it udev?
I don't know the role of those softwares and what they do.

"HP x2 Detachable" doesn't say which one YOU have. That is a family
line of netbooks/tablets. There are models within that family and even
submodels. I did a search at hp.com on what you gave and picked the
first one that show up in its results, which was:

https://support.hp.com/us-en/product...01_title_r0001

When I clicked on the "Software, Drivers and Firmware" button on the
left side, that took me to:

https://support.hp.com/us-en/drivers...model/11572368

The *only* operating system listed is Windows and *only version 10
64-bit. HP provides the drivers only for that setup which is typical of
these type of computers. They don't support earlier versions of
Windows, they don't support any later versions of Windows, and they
definitely don't support any non-Windows operating systems. What makes
you think you can run *NIX on your tablet (with detachable keyboard)?
Unless exposed by standard firmware protocols (APM, ACPI), you need
something (software or device definition) for the OS to access the
hardware.

All hardware needs an interface defined in an OS, so the OS knows how to
communicate with the hardware. If that tablet has a chip to monitor the
battery statistics, something has to tell the OS how to communicate with
that chip. I can only guess which driver package from HP is used to
interface the OS to the hardware, like maybe the "HP PC Hardware
Diagnostics UEFI".

You could try to use programs that poll APM or ACPI functions to find
the battery. Windows expects the battery firmware to get exposed via
ACPI.

https://docs.microsoft.com/en-us/win...implementation

One version of ACPI is documented at:

http://www.acpi.info/DOWNLOADS/ACPI_5_Errata%20A.pdf
Section 3.9 Battery Management, page 45.

To find how Debian might use ACPI to monitor/manage the battery, I did a
search, which was:

https://www.google.com/search?q=debi...ery+management

one of which was:

https://linrunner.de/en/tlp/docs/tlp...anagement.html

Perhaps in the distro you installed, you didn't do a custom install;
that is, maybe you have to select one of the non-default packages to
install to get ACPI battery management included in that OS. Maybe
Debian doesn't come with ACPI battery management functions included or
in its distro, so you're stuck using non-distro tools.

From cursory reading, *NIX users have complained that some distros are
not as efficient on battery life as Windows, and I've seen TLP mentioned
as a solution. Never used Debian but I did find:

https://packages.debian.org/jessie/x...-power-manager

and which says it does battery monitoring.

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.

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.

The BIOS is the last available.
I've just wrote to the developper of lshw because it's the only software
able to see my battery.
And you are right: I also will write to HP support and light a candle at
Notre Dame de Paris

Thank you,
Sylvain
