For a while now I've really loved my Dell XPS 9305. It was the first machine that really worked with Linux out of the box, for me. Nothing was disfunctional. Not a single device. It ushered in my "Year Of The Linux Desktop" (2021), and I found it so nice to work with I bought it from my former employer when they went under. Everthing was great, well except for theese pesky forced reboots (crashes), which happened to occur always when I was away from the machine so as to limit my ability to gain any hands-on insight into the true cause. At least they were infrequent, every few months. Still it was very unsettling, as without any warning whatsoever the machine would die. The system log (journalctl) was completely blank as well, as if the machine's power vanished, though it was on battery.
I ignored it, however I was lucky it would only rear up once or twice a year, and having come from a long history of trying to use Desktop Linux I was more than willing to take an occasional hiccup, even one of this severity, if it meant computing freedom finally.
I notice something odd during boot though, a slurry of ACPI errors which upon surface investigation sounded (from prominent discussions) as if it was due to lacking ACPI support of some kind in Ubuntu itself. Due to this assumption and having zero time to push further I lived with it.
But again it would result in stuff like this:

One day, and on a whim, I decided to follow this up. Instead of searching for ACPI+Ubuntu errors, I went with the most obvious route, rather, "forced reboots on Dell XPS". The page exploded. Everyone and thier mother was suffering, Windows included, from the most trivial reboot/crashes which haven't been a problem since the earth was cooling 25+ years ago. After sifting through pages, over years and years of discussion, the result was that, for the most part, Dell couldn't write firmware any more. What was once a common and accepted academic assumption, that your system won't crash due to anything hardware/firmware related, suddenly didn't hold. Secondly, the expectation that the vendor (DELL) actually cared to address the issue which was affecting ALL downstream OSes was also not the case. Many had tried BIOS updates which, allegedly, were claimed to address the issue, one wich from what I learned was related to the board's ACPI and Wireless card's integration, or rather lack thereof. The Wifi chip would occasionally request to going into powersave mode, and the ACPI would say in layman's, "I have no idea what you're talking about, lets force-reboot!" after which the charger (if present) is no longer able to be detected until a cold boot! None of the updates, from DELL had any affect, from what others were saying, and I even tried to disable powersave on my wifi, which unfortunatley has not stopped it.
I'm sure it somehow could be worse, but the fact that it is 2025+ and the laptop has, for all intents and purposes, the functinal reliability of a system with Win98, is flabbergasting. Whats old is now new again. Ultimately Dell does not care and refuses to asses such a critical usability flaw in an otherwise very usable, non-obsolete, system.

Farewell soon my friend.
