Screen dimming and charging problem on my AMD Laptop since 2-3 months

Support
,
1

I’m not sure exactly when, but i guess after 2026-02-23 or after 2026-03-23 stable update i faced several issue with my Laptop.

  1. Laptop is booting with low brightness 40% when booting into Manjaro/KDE.
  2. Laptop isn’t charging above 71% when Manjaro is running, but it charges to 100% when its powered off
  3. I switched back from LTS 6.18 to 6.12 with the newest stable update from 05/02 but still nothing changed.

Some systems allow the operating system - in this case Plasma - to control the charger but not when powered down.

I suggest you look at your Advanced power settings - see if it is configured to stop charging at 71%.

With Lenovo systems the charge limit is set in the firmware, thus it work even when the system is powered down.

Tuxedo systems may be different - as I recall they are based on German Schenker which uses Clevo barebones for some of their systems.

I have Intel based InfinitibookPro14 gen8 which does not provide an option to set a charge level.

I don’t had any problem’s before… all this wierd bugs came out of nowhere after one of our Distro updates, it was working fine for several year’s before and i didn’t made changes inside Manjaro/Kde.

There is nothing to adjust.

I am thinking that one of the cells in your battery is dead.

Condition is 65.8Wh where it was 91.2Wh when it was new.

Open a terminal and run

upower --battery

look for battery.energy-full, battery.energy-full-design and the battery.capacity numbers.

Yup, a cell has died - that can be deduced by the 98% after the charge number.

This has nothing to do with an update but a result of wear and tear - that is just how it is.

One can prolong the life of a modern batter by avoid charging to full (100%) capacity and avoid deep discharge (0%).

This is a known issue with batteries - search the Contributions > Tutorials for utility script charge notifier

Hmmm, but under warning there is none.

I used that laptop so rarely, im wondering why there is tear already on that battery
:frowning:

I’m actually mostly try to stay between 20%-80% for max lifetime… that’s why im confused why that battery state is in this mess.

Im try to load not much above 80% and not discharge much below 20%… to be in the perfect sweet spott.

I can’t really believe why my battery is damaged already… i maybe had used that Laptop 800hour’s i guess.

Batteries are difficult - you cannot see inside.

I worked with security systems for a decade - they all contain leaded-gel accumulators.

During yearly service I routinely replaced those accumulators - to ensure stable operation.

Especially fog devices was vulnerable as the batteries was in close proximity to the heat element - they often died within 12 months.

A slightly different idea for the second problem with the display: do you have tuxedo control panel? It might expose some more firmware settings (like remembering or not the brightness).

11

I used the control panel in the past, but i uninstalled it year’s ago.

KDE always saved my Brightness correctly, but after a system restart since 2-3 month… it will always switch back to 40%… that’s said, i have no problem with Energy savings when then Laptop is idle… the brightness value’s restoring correctly after the system wakes up from dimming or even sleeping… this problem’s only occur after a reboot.

Im wondering if the battery problem are connected together with the low brightness somehow.

Since both problem’s occur after the same time.
