Linux can increase the risk of laptop fires?

It appears that even most Linux users will admit that battery management in Linux is bad. - https://www.reddit.com/r/linux/comments/1gtgpkb/does_linux_have_better_battery_management_that/

Battery management related factors in which off-gassing can occur:

Overcharging: Excessive charging can cause the decomposition of electrolytes within the battery, leading to gas generation.
Overheating: Like off-gassing, excessive heat can trigger thermal runaway by destabilising the battery’s internal chemistry.
Over-discharging: Discharging a battery beyond its recommended limit can also result in the release of gases.

Notice how, even though the laptop is sitting on burning coals, and is already engulfed in flames, Linux is still running without issue.
- linux is cool
As if, my only dead or even bloated batteries are in my gaming windows laptops. My current system also isn't overheating on idle, in fact I occasionally forget to turn it off, because of how quiet it is.
battery management in linux has always been awesome: run only needed services, dont abuse resources more than needed. under linux laptops battery always lasted way longer during usage (standby should be the same,right? eh, except for apples crapbooks - see below) than the tests running windows. one thing that i could not compare directly (didnt do that test) is that on linux laptops batteries lasted long-term seemingly way longer than those of roughly same time bought windows machines but those were used by others so i could not really tell for real.

however the superflous systemd bugware changed with the tradition of not needlessly exhaust resources after beeing forced by some entity into lots of distributions, but systemd is not linux and you can use linux without superflous resourcedepleting crap like that.

however i am not a user who needs standby or uses hibernate and i completely dislike screen savers like reducing brightness or turning off monitors "after a while". luckily i use linux and can set such settings as i want AND they also work as configured (see crapbook fuckups below). for security reasons i lock my linux screen when i need to, otherwise it runs on the brightness i set while i use it, same on battery or not, wether battery low or full.

i luckily cannot compare current windows act-as-if-windows-was-powersaving as i haven't administrated one of those malware-distribution-platforms from microsoft for ages.

at work i have to use a crappy apple macbook and battery management is a full -10 (minus!) hell (out of 0-10 points) there:

shutdown does not always really shutdown even if the display is already off, causing full battery depletion during weekend with a "shutoff" system wheee!

after real shutdown closing the lid sometimes boots the crapbook pro again m(

closing the lid should cause standby, but doesn't always (but you cannot know as the lid is closed and opening it should stop the standby again) also causing full bettery depletion without having a way to "really" prevent it.

minutelong monitor-recalibration-flickering after monitor-only-standby (forced by company settings) during mandatory-when-leaving-seat screen lock lasts as long as i consider it an impediment causing useless amounts of overall-energy be drained (mine, that of the companies office lights and heating, the monitors as well as the battery usage during minute-long just-re-starting-the-fucking-monitors which is usually instant under linux)

also crapbooks beeing actual office heaters as hot as one does not want to touch any more dont 'manage' batteries, they just drain them, luckily my work crapbook didnt have 'that' bug yet but hundreds of other bugs seemingly enough for its own youtube channel about work impediments presented by (cr)apple, also draining "my" energy much more than needed as well as making work progress as slower causing (bot only) the battery life to be less effective. crapbooks battery management alone is worth naming the whole thing a "crap"book.

linux power and battery management works just fine for me, no hassle, does what it should and what i need =)

the linked page about TLP shows more how to install it than what it does, only the thing about not fully charging the battery could be helpful, but is not what i want to use right now, but thanks for the information that it exists ;-)
