Today, on my #blog, I'm reflecting about what ACPI state S0ix (aka s2idle) means for the nature (and evolution) of laptops. It's been an interesting piece to research as I was totally unaware of the changes the PC platform had undergone since 2013 (when I bought my machine before the one I'm using right now).
With a lot of great input from Stuart Henderson on the tech@ mailing list, I could finally find a quicker way to update #OpenBSD on my #intel #MacbookPro that suffers from an #ACPI regression and thus needs a custom kernel.
Here's the updated tutorial on patching the system, I added a guide on keeping it updated:

Well this is odd. Emacspeak on this HP computer shows:
Power off-line, battery discharging (25% load, remaining time 0:39)
ACPI, though:
Battery 0: Discharging, 25%, discharging at zero rate - will never fully discharge.

I would suspect an ACPI problem.
Sometimes, it is best to pull the mains, and let the caps drain. Do not be in a rush to reboot.
OFF does not always mean Really OFF.
I thought that booting Seriously Bad Computers in ACPI mode is crippled compared to booting in DeviceTree mode.
NanoPC-T6 is otherwise. Same 6.11-rc2 kernel gives working system in ACPI mode and fail-to-boot one in DT.
DT = no USB, no PCIe while rootfs is on NVME cause it worked fine in ACPI mode.
And DT is from 6.11-rc2 kernel.

It's really nice to see that #ACPI support was added to @zephyr this week. Also super cool to see @seeedstudio's XIAO ESP32S3 as a new supported board!
