Dell laptop, and I decided to salvage it by replacing the RAM and NVMe drive and installing Linux. (I considered updating the BIOS but was lazy and, perhaps, insufficiently paranoid.) Seemed to work well for months, but my BIOS/UEFI struggles this past week make me a bit suspicious now, esp. seeing messages like these:
My friend -- originally from China but living in the US for many years -- traveled between the US and China a few times, likely with this laptop, so there have presumably been opportunities for state actors to install backdoors into his UEFI. Hmmm.
