< asking for advice about computers
If you are looking for a laptop that can run free software from the BIOS up, I'd recommend taking a look at Thinkpenguin, Technoethical, or Minifree. They all sell refurbished Lenovo Thinkpads (T series and X series) that come pre-installed with a free BIOS (Libreboot/Coreboot) and a libre GNU/Linux distribution. Happy hacking!
