I've actually had good enough luck with USB-C that I leave my Acer's native power supply at home when I travel.

There are some decent USB PD hubs available that will power/charge the laptop while also supporting other USB plugins, and some also have secondary video (by HDMI or USB-C) and even wired Ethernet. Here's one example

P1 *should* be quite nice.  Hope you got them on sale.

Modern power supplies are pretty tricky.

Lenovo support should be able to handle this.  Of course there are a few
problems if it involves returning the device:

- how can you eliminate confidential files from the system before
  returning it?  Theoretically very difficult with an SSD (wear-levelling
  is magic).

- all your work configuring the system needs to be redone when you get it
  back.

- you are missing the machine for a few weeks.

I think Lenovo offers a service that allows you to retain the disk when
you send the device in for repair.  It may cost.
