Toshiba Laptop battery 0% problem

[noobandnothing]

Hello bro, Thanks for your kernel ,I always use it. Excuse me, My laptop always show 0% battery . This issue happens with all distro

I tried much but I failed . To be honest (I) , I tracked issue and found that issue started with kernel 4.15 (It was working until 4.14.X). I knew from trying all old ubuntu distro , I found that it was working with 16.04.6 (with kernel 4.4)and issue started with 16.04.7(with kernel 4.15) . I tried all version until I found that issue happens with 4.15 or higher (until now).

Have you tried with a recent distribution?

Recent kernel versions should be supported with current Debian and Ubuntu LTS distributions. Apparently this problem is due to the outdated linux-firmware package.

I am using last Kubuntu 22.04 with latest kernel ,also I made sure that latest linux-firmware package is installed. Also I tried with ubuntu ,debian , fedora,archlinux , All has the issue (0% battery perentage) .

I found this possible solution in several forums.

1. Try adding this kernel parameter in /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=copy_dsdt"
2. sudo update-grub
3. reboot

Thanks bro for replying ,Unfortunately it is not fixed ! IDK if Changes which were added in 4.15 caused this issue until now ! https://kernelnewbies.org/Linux_4.15

Try: acpi_osi=Linux acpi_osi=! acpi_osi=Windows

Tried to put 3 props in GRUB_CMDLINE_LINUX_DEFAULT (one by one ) but unfortunately it is not fixed !

I found this : https://linux-hardware.org/?probe=14ac6c1f51&log=upower

Same battery model and it doesn't have this issue ! then something else should be the cause.

[noobandnothing]

hello pro I found the cause : It is if statment was added in 4.19.86 kernel https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/drivers/acpi/acpica/evregion.c?id=v4.19.86&id2=v4.19.85
