DELL Latitude laptops. They’re designed for work, come with repair guides from DELL, and have upgradeability. The 5310 is one of the longest-lasting laptops for battery life you can get for $200-300 on ebay (over 8 hours battery video streaming, I’ve done this) that still has half decent specs (16-64GB RAM upgradeable, upgradeable m.2 wifi / bt adapter, NVMe SSD upgradeable, i5 10th gen)
Runs fine on Debian Stable
Latitude is my rec, not XPS. IDK why the XPS always seems to have issues.
As for “stupid hybrid graphics”, my HP Gaming 15 is a few years old now and still kicking… AMD/nVidia GTX dual graphics. Only reason I had to replace a board was because the heatsink wasn’t attached properly from the factory.
And yes, it is a linux laptop too.
