Can I recommend a ThinkPad P series with Linux and some tuning? I've had nothing but good experiences for the most part. The only things I wouldn't recommend is a 4K laptop screen, Lenovo's prices for upgrades, or trying to get good power management in Linux. Make sure your CPU fans are turning when hear goes up or fix thinkfan config and check lm-sensors and don't use hibernate and force sleep mode to old/compatible/S3/other OS/Linux or whatever the option is called for you. Note about windows sleep mode: Microsoft worked with new firmware manufacturers for laptops to include sleep mode that's actually not sleeping but the CPU runs at 400MHz with the screen off. All your apps are still on, your computer is online, and things are happening while you think it's asleep. It uses very little power so actually being asleep or being in this mode doesn't change battery drain too much. However Linux won't play ball and it'll just wake up your computer and drain your battery while heating up your laptop bag. Turn it off.
