Ubuntu Linux snuck into high-end Dell laptops

My work machine, a Precision 5550 (XPS 15) has never been able to reliably wake from sleep. Ubuntu, Pop!_OS, Windows 11- it doesn’t matter.

Same, with other Dells. There was one where I analyzed the BIOS ACPI tables and concluded it was impossible to wake from sleep due to bugs I've found: I can't find my old post, but https://www.reddit.com/r/Dell/comments/kolf5f/patching_the_d... is a good summary.

Error on Dell ACPI tables are usual: for the 5510, see https://gist.github.com/jamal-fuma/17d2d605280a52376326384c4...

I also remember someone doing deeping ACPI table modifications to limit the power draw on the Xeon Laptops.
