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).

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?

Thanks,

Rafael
