For future reference, if one is intent upon buying an Intel-based notebook for use with Ubuntu then a purpose-built System76 lappy is one time saving option worth checking out:

Note. I’ve never done business with System76 etc as I’ve no need for a laptop.
I prefer the more hands-on approach of doing a GNU/Linux-friendly desktop build whose components I can research, co-ordinate, trouble-shoot and replace / upgrade on my own while avoiding as much as possible intrusive pitfalls such as proprietary out-of-band ‘remote management’ technologies.
Experience has taught me to avoid bleeding edge technology in favor of getting premium examples of the preceding generation of hardware in order to access and benefit from the most mature PCB, UEFI / BIOS and driver support along with sequential track records of user feedback.
When it comes to computers the latest is only the greatest if it works. And usually by the time it does - as the result of many hair-pulling hours of unpaid time spent plowing through forums - it’s no longer the latest nor the greatest.
