During the installation of Kubuntu Desktop amd64 (Jammy 22.04.2) on an Lenovo ThinkPad X201, and Lenovo ThinkPad Yoga 460 no message asking the user to plug in to a power source is displayed at any point during the installation.

The laptop was already plugged in.

I used the the following build:

[EDIT]
I tested the installer again without being plugged in and the message wasn't displayed again.

This bug is also present in the Ubuntu Desktop (jammy 22.04.2) installer. I used the following Image:

on the following machined:
- Lenovo ThinkPad X201 (64Bit Intel Core i7-M 620 @2.67GHzx4; 4GB RAM; Intel HD Graphics; 1xSSD-160GB)
- Lenovo ThinkPad Yoga 460 (64-Bit Intel Core i7-6500U@2.50GHzx4; 8GB RAM; Mesa Intel HD Graphics 520 (SKL GT2); 1xSSD-256GB)

I start to think that I understood the instruction of the testcase wrong. I think the author meant that the icon in the top bar should display the correct state.

If this is the case, there is no bug and the systems behaved as expected. I will talk about this tomorrow with my team in the standup.
