Hi, my framework laptop is bluescreening after a few minutes of mild use and afterwards, then after booting back up the laptop says that there is no boot device found. This fixes itself eventually after a few hours and starts to work again for a few minutes. I also recently updated the BIOS. I also hadn’t used my laptop for about a year because of a broken screen until I recently replaced it.
Hmm, sounds like your internal boot drive might need to be reseated. Are you able to boot reliably from a memory stick?
Your BIOS upgrade and screen swap might be causes, but I’d suggest focussing on the drive to start with.
