I was trying to install Qubes 4 on my brand-new Librem 13v2 and it didn’t quite work. That’s fine, I was just giving it a try. However, it seems I got myself into a pickle now. My Librem doesn’t seem to boot anymore.
When I press the power button, the “on” LED turns on, but there is nothing on screen (not even the Purism logo screen that lets you press Esc for boot order), and a few seconds later, the “on” LED simply turns off. I tried pressing Esc just in case that might bring me to the boot order screen, but no, it doesn’t change anything: nothing on screen and the “on” LED still turns off soon after. So I can’t even try and restore PureOS from USB.
How can I diagnose this better, and/or how can I fix it?
