- Thinkpad Carbon X1 14" (i7-5600u). Everything worked out of the box with Arch Linux at the time. Best experience I've ever had.
- HP Envy 13z (R5 2500u) everything works today but the out of the box experience was very poor. Windows update installed an APU microcode update that broke the Linux AMDGPU driver and had to run an -rc kernel for awhile. Took a year to get a touchscreen driver and years to get the driver for the tablet sensors (rotation, etc.). Total wait of 3 years for all features, but I never had the desire to use it as a tablet so I was okay with it. Sleep works but this laptop had awful battery drain issues in sleep (30% per day).
- Dell XPS 15 7590 (i9-9980hk) - Sleep is broke in both Linux and Windows. Everything else works well, including, notably, NVIDIA Optimus / DRI PRIME.
- Asus ZenBook 14 (R7 5800U) - second best out of box experience. Touchpad is connected via i2c and my Gentoo install didn't have it enabled. I'd never bumped into i2c hid devices other than touchscreens.
Yes! How can they sell these like that? My XPS 13 will never go to sleep correctly, either the screen stays on or it doesn't shut off correctly, in Windows or Linux. You'd think that this is the basic feature a laptop has to have. And it's not just me, their forums are full of people having problems and their support has no idea. They were sending me guides for latitudes from 2012.
Definitely not going for Dell hardware again.
