FW16 powering on the mainboard only

Has anyone tried powering a FW16 mainboard on its own. I.e. when removed from the laptop?

Using a display port card to connect an external display and a usb keyboard.

For me, it does not boot. It only seems to boot when connected to expansion bay and battery.

Is this just me, or is it the same for all?

I believe that there is another user on here who is doing that. If you don’t have the optional RTC battery connected I would suggest that, to keep the settings when the machine is off of power.

Edit - found the thread: Booting up board without full laptop

Ok. So that at least confirms it is not just me.

The blue/red situation needs looking at so we can consistently boot when the mainboard is alone. It will probably wish to throttle as the fans are not there, but it should boot.

This might be my next EC investigation, mod that I look into.

I already have a similar case.

When I use the efi “ectool reboot rw” to get the EC running my modded version, if the psu is not present, so only battery present, it reboots, if the psu is present, it switches off, and not reboot.
