Brief summary

When the laptop is fully charged, it keeps switching from Charging to Fully charged.

How reproducible

100% reproducible.

How to reproduce

1. Install an operating system that uses XFCE, like Qubes OS.
2. Make sure that the battery is fully charged.
3. Observe the battery indicator for about 10 minutes.

Expected behavior

When the battery is fully charged, it says Fully charged and doesn't change.

Actual behavior

It keeps switching from Charging to Fully charged.

Screenshots

No response

Additional context

It seems to happen with both USB-C charging and regular DC jack charging.

I'm not sure if this can be fixed by firmware?

Does anyone know how to stop these annoying popups?

Does it happen with the default battery thresholds of 95-98?

[wessel-novacustom]

@mkopec Yes. So far only tested for Dasharo coreboot+UEFI.

Adding screenshots:

This happens while the power adaptor is plugged in and the battery is fully charged, it keeps switching between both messages around every 5 minutes (sometimes even more often).

Also confirmed under Heads (rc5).

I see the same behavior on my NovaCustom NV54 laptop with Qubes 4.2.3 using XFCE.
It happens default thresholds and custom thresholds (70-98 in my case) and regardless of charging method (USB-C PD or normal PSU).
Running Dasharo (coreboot+UEFI) v0.9.0.

This is happening to me as well on Arch Linux with KDE Plasma 6.2.5.

I get constantly changing indicators for charging, also, for some reason, the battery seems to loose power even when the laptop is plugged in the whole time. Battery thresholds are on default.

So far, I haven't managed to reproduce this on V540TU, Dasharo v0.9.0 and Qubes 4.2.3 kernel-latest. I've waited for ~10min on both DC barrel jack and USB-C, Qubes remained at Fully charged as expected, using both the default and custom thresholds. I will also try on V56.

@filipleple I'm not 100% sure about the V54, it happens on the V56 Series for sure. You might need longer than 10 minutes.

@marmarek Maybe you have seen this in Qubes OS, too?

[PerAstraAdDeum]

I can confirm this is ocuring on the V54 (Intel-only model). However, I don't know hot to reproduce it. I've been seeing this error for quite some time now, I always thought it'd probably be a KDE issue though.

Maybe it is tied to a certain battery load percentage.

I haven't managed to reproduce this on V540TU, Dasharo v0.9.0 and Qubes 4.2.3 kernel-latest.

I run a very similar configuration and confirm the problem:
V54x_6x_TU/V54x_6x_TU, BIOS Dasharo (coreboot+UEFI) v0.9.0 07/17/2024

I think you need to spend around 2 hours on the machine to notice it, roughly
