Framework Mainboard: No graphics via USB-to-HDMI when switching on immediately after connecting to power

[probonopd]

Hardware:

• Framework Mainboard (bare board, no battery attached) with 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz
• USB3-HDMI (DP Altmode) adapter

When powering on via USB-C (using a switchable power socket) and then _immediately pressing the power button, more often than not I get no usable HDMI output via a USB3-HDMI (DP Altmode) adapter. (In these situations, my HDMI display either doesn't turn on at all or says "no signal").

This leads to me having to wait ~5-10 seconds between powering on the switchable power socket (which has the USB-C power brick that connects to the Framework Mainboard) and pressing the button on the Framework Mainboard. This is very annoying.

Please test the following:

• Attach a USB3-HDMI (DP Altmode) adapter to the Framework Mainboard (bare board, no battery attached) with 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz, and attach a HDMI display
• Have it powered off for ~10 hours (like, overnight)
• Power it on and then immediately press the power button on the Framework Mainboard
• Do you reliably see a picture on the attached HDMI display?

Would have updated to the latest firmware but the Windows update tool doesn't allow me to do so without having a battery. I have no battery, just the bare Framework Mainboard (bare board, no battery attached) with 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz. This means I cannot get firmware updates (at least not using the Windows tool).
