Hi, The *CMOS *(BIOS) battery is installed, yes. The main power battery is not - I can try that later but obviously I should be able to power on the thing when the battery is not installed. FWIW, stock BIOS does not have this problem.

Have you tested with a battery installed? I'm imagining a hardware glitch on shutdown that causes an EC failure. Many older desktop platforms wouldn't even power on if there wasn't a CMOS battery installed.

Morning, Just checking in to see if anyone had some advice on where I could look
to try and fix this problem. Note that it also happens for sleep and suspend modes, not just shutdowns.
Thanks, Rafael

Oh, there's not currently a battery installed - so that would do it.
Thanks for a lead.
What's the path to fixing that? Different EC blob extracted from stock
BIOS, something in Coreboot to check?

sounds to me like AP shutdown is causing the EC to power off as well,
so it's not active to respond to the subsequent power button press. Not sure why disconnecting AC power would reset that though, unless you are also disconnecting the internal battery as well

Hi, As folks may have gathered from my other question about the GCC build
environment, I've been playing around with the old X2100 port (>>>> https://github.com/mjg59/coreboot/tree/x2100_ng%3E%3E%3E%3E ).
I got it to build and added the latest version of MrChromebox's
Tianocore, but there's still one issue that keep is from being very useable.
After flashing / plugging in the machine, the power button will turn
it on, but only once. If I shut down any OS, or even if it goes to sleep or suspends, the power button no longer has any effect so the only "fix" is currently to unplug power and re-plug it.
Where might I look for causes of this? Is it a shutdown state thing?
ACPI?
