^ That suggests Dell machines have their own charging threshold GUI for Windows, along with firmware ("BIOS") options that could presumably be accessed from Linux via sysfs.

# tee /sys/class/power_supply/BAT0/charge_control_start_threshold <<<"49"
# tee /sys/class/power_supply/BAT0/charge_control_end_threshold <<<"51"

^ That pins the battery between 49-51%, which results in it being bypassed once the battery is half full (or half empty, if you prefer).

Those values only change when I boot Windows. Otherwise the charge control ECU maintains the values set from Linux.

EDIT: as the OP is a Windows refugee they might appreciate this GUI that allows D-Bus control of charging thresholds by non-root users:

Might only work on ThinkPads though.

Its config, or script, wheris that settings?

Those are sysfs (virtual) files, and should be writable - either directly or with the sysctl utility. You could use something like rc.local or a crontab to write them on startup.
Alternatively, just install tlp. It has many useful features and the configuration file is well documented.

archie:~$ cat /sys/class/power_supply/BAT0/cycle_count
59
archie:~$ cat /sys/class/power_supply/BAT0/energy_full_design
50450000
archie:~$ cat /sys/class/power_supply/BAT0/energy_full
50070000

Why is there still no permanent connection mechanism to AC for laptops without harming the battery?

As HoaS explained, there is. If you set the embedded controller to stop charging at some level less than 100% (and only start charging again at some threshold lower again), then it sill stop trying to "top up" the battery constantly.

If the laptop is kept plugged in with the battery at 100% that will degrade it over time

Indeed. The things that will kill li-ion cells the fastest are heat, repeated deep-discharges, and continuous trickle-charging... Two of which you will get in spades if you leave a machine plugged in with the EC set to maintain 100% charge.
If you intend to store a battery (functionally what an always-on-ac laptop is doing), you want it at 60-80% and as cool as possible.

This is uncomfortable, always watch to level of charging and always to plug on\off power cable.

And what to do if laptop not allow remove battery, new laptops have build-in unmovable battery?

This "battery care" behaviour is run by the embedded controller, it has it's own nvram and whatnot since it needs to handle charging when the machine is off etc.

Most laptops I have seen have manufacturer bloat software for tweaking charge behaviour, but without it windows will just go for maximum runtime. Consumers rate portables on runtime after all, and replacement batteries make money...

Interestingly if I set the charge behaviour in Linux by simply writing to the files it persists between boots and even if I boot OpenBSD, Haiku or 9front. Unfortunately Windows will "fix" things and start to break my battery again, which is very annoying.

You mean SuperComuters? But SuperComuters using Linux not for Desktop but computing only?

Quite a few of them run Ubuntu, actually

There are other reasons: Windows doesn't allow edge scrolling with the touchpad; it doesn't have a PRIMARY clipboard (select the text to copy then middle-click to paste); amdgpu doesn't work so AMDGPU-PRO has worse framerates, runs hotter & drains more power; I can't see any of the source code. Under Linux I can see

archie:~$ ls /sys/class/power_supply/BAT0/charge_*
/sys/class/power_supply/BAT0/charge_behaviour
/sys/class/power_supply/BAT0/charge_control_end_threshold
/sys/class/power_supply/BAT0/charge_control_start_threshold
/sys/class/power_supply/BAT0/charge_start_threshold
/sys/class/power_supply/BAT0/charge_stop_threshold
archie:~$ cat /sys/class/power_supply/BAT0/status
Not charging
archie:~$

^ Setting those values allows me to fix the charge rate to 50% battery so I can leave the laptop plugged in (for best games performance) without wrecking the battery with continuous charge/discharge cycles.

This laptop is a few years old now:

archie:~$ cat /sys/class/power_supply/BAT0/cycle_count
59
archie:~$ cat /sys/class/power_supply/BAT0/energy_full_design
50450000
archie:~$ cat /sys/class/power_supply/BAT0/energy_full
50070000
archie:~$

Most of that damage was done by bloody Windows

I haven't tried 11 but I've had a few Windows 10 systems running for quite a while in that state, both bare metal & virtualised.

You missed the punch line that is the root of all such actions . . . the "wanting" is the problem. Everything that stems from that impulse is "tainted". With out that "wanting" no rationalizations are needed.

what technically wrong with music images?

Nothing at all, I just ripped them to ogg/vorbis no problems. CDemu + K3B on gentoo, no Windows (7 or otherwise) required.

If you don't explain how you're trying to extract the audio (and with what software), then I have no idea why it doesn't work for you.

The expansions only come with 5 new tracks each IIRC, so the number sounds right. Dunno about track order though, I expect that'll come down to how the files are named.

Personally I don't have any moral dilemmas when it comes to screwing Bethesda out of a couple of bucks for a 25 year old game they had nothing to do with making in the first place. Still charging for repacks of something that old is really scraping the money-grubber barrel IMO.
That said, I've bought Quake and Quake 2 at least 3 times each over the years. Once when it was young, once to have disks that actually work, and again because GOG is awesome and it was dirt cheap.

Did I mention you can get a legit copy of Quake 2 with both expansions and the netpack for $2, DRM-free on GOG already? Why are we even discussing pirating it?

@deepforest If you PM me your email address, I'm quite happy to gift it to you on GOG. Or pirate it if that's what floats your boat, I'm not one to judge. Just don't expect people to help you pirate it, at least not here.

I use GNU/Linux because it's free, not because it's free. Also Windows is a horrible OS, and has been getting more obnoxious with each release since XP.

@deepforest . . . It's not about money. It's about principle. There is no excuse for theft, ever. The "wanting" is the problem that is the root of much suffering. Learn to let it go and be happy . . .

Agree. Its yet soviet philosophy here in heads. People were very poor and could not afford anything, so theft was welcomed, and this is one of the reasons for the collapse of the ussr.

First main thing its - Hope for better its one thing to do now for all FreeWorld.
Second main thing its - supporting of FreeWorld to Ukraine in fighting against demons of mordor.

You talking about 10 and 11? Because XP and 7 is blocked after while if licensed key do not entered.
