Hi there!
The Laptop Repairability list is probably the most inclusive repairability list we have. We just don’t do a ton of repairability ratings on laptops, unfortunately. In general I can recommend HP and Dell notebooks, both companies have a dedication to repair and host free repair manuals, and quite often make repair parts available to users. The best research you can do before purchasing a laptop is looking for those service manuals and seeing how the device is constructed, to look at modularity and upgradability.
Once we get more data on that list we’d be happy to sort by use case and offer a search option. Thanks for your interest!
