Introduction
This page is a comparison of laptops that can be run with completely Free Software. It applies to the following laptops:
- The ones that can be run with completely Free Software, but didn't get certified because, at the time they were produced, the certification didn't exist yet.
- The ones that are RYF certified
- The ones that can be run with completely Free Software, but that cannot be certified because some hardware (for instance the webcam) will not work.
A user cannot free a laptop if nonfree software is required to boot. If more work is needed, the laptops need to be moved to Group:Hardware/Computers/Laptops/Laptops_with_fatal_flaws instead.

↑ 1.01.1 It can be replaced by:
- Coreboot code, with text mode or framebuffer graphics support
- SeaBIOS's option rom that gives VGA compatibility
- ↑ 2.02.1 Some of the impact of not updating the microcode can be found in Intel's CPU erratas, like the Core Solo/Duo erratas. A good way to avoid the issues described there is to have a CPU that has the bugs you care about fixed in hardware: The more recent batches you get, the more erratas are fixed.

↑ There is a big risk of breaking the laptop: Some time ago, lots of users tried and broke it, they couldn't buy the laptop already flashed, so they tried it. They broke it because the instructions to switch from the original BIOS to free BIOS replacements are complicated.
That's due to some restrictions of the original BIOS, which tries to prevent easy reflashing.
- ↑ Once the free BIOS replacement is flashed, reflashing is easy, but still dangerous: if the free BIOS replacement doesn't work, then the user has to disassemble the laptop and reflash with an external flash programmer to recover.
- ↑ If your MacBook has the right flash chip, flashing it is easy: if the free BIOS replacement doesn't work, then the user has to disassemble the laptop and reflash with an external flash programmer to recover.
