Fujitsu Laptop Battery only updates on reboot and stuck on percentage (Arch Linux)

by |Published

Hello I Installed Arch on my new laptop, however, the battery percentage/percentage update seems to be broken, I have never seen this before and could really find anything useful which might help.

I installed ACPI and tried to downgrade upower, also disabled session restore in KDE settings as well as fast boot inside UEFI.

I booted from USB into ubuntu and the battery works there, I used lspci -nnk to view the modules/components and what drivers they use, there are only two things that don’t match arch’s lspci -nnk output.

The driver (and kernel module used) for the Signal Processing Controller is intel-pmt on Ubuntu and intel_vsec on arch.
The driver for the Serial Bus Controller doesn’t seem to have any modules or drivers present under Ubuntu, but on Arch it uses intel-spi as the driver and spi_intel_pci as the kernel module.

The Laptop in question is a Fujitsu Lifebook A3511 (i3-11th gen)

For any further clarification I am happy to blindly follow your shell commands ;D
