Battery recognition -- Linux

[Sylvain_68]

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?

sudo apt install batmon

crude but better than nothing.

[Sylvain_68]

Thanks for the tip, but the battery is still not recognized.

I think of a bios problem: may be it doesn't "show" the battery...

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.

Hi

So try....

https://lubuntu.net/downloads/  which is relatively quick and easy from a USB. 

Same stable (Debian and Ubuntu) may give different results.

Also OpenSuSE did / does give battery info directly, so perhaps consider their build service.

Unless you are satisfied it is a BIOS/ACPI problem.

[Sylvain_68]

It seems that the problem is by ACPI side.

The 'lshw' soft identifies correctly the battery. This soft gathers its pieces of information directly from the BIOS.

Is there a way to get ACPI to gather BIOS configurations? DSDT ?

Thanks,

Sylvain

Hi

I don't know.

Install TLP for better power management

You do have some options to manage the power from the system settings. However, if you utilize Linux on a laptop, you may want to reduce the battery usage.

To help you with this situation, you can install TLP – which is an amazing tool that monitors your computer and implements the best techniques (automatically) to optimize the battery life of the Linux-powered system.

You should also consider installing this if you want to prevent overheating in Linux laptops.

To install TLP, type in the following commands in a terminal:

sudo zypper install tlp tlp-rdw
sudo systemctl enable tlp

Install Battery Monitor on Ubuntu and Debian

Let’s install from PPA:

$ sudo add-apt-repository ppa:maateen/battery-monitor -y
$ sudo apt-get update
$ sudo apt-get install battery-monitor -y

That’s all. Battery Monitor is installed on your Ubuntu or Debian system.

Try the following command:

$ upower -i `upower -e | grep 'BAT'`

To install acpi:

$ sudo apt-get install acpi

Once acpi is installed, run the following command:

$ acpi -V 

[Sylvain_68]

ACPI is already installed.

Hers is the result of acpi -V :

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

Have you tried changing the settings in the  /etc/laptop-mode/laptop-mode.conf   file to enable more of the features you want since Debian is installed in a notebook with a battery?

See the Man pages at the link below this line.
