After removing the tlp package (kudos to Andrea), the NetworkManager is able to
connect using the laptop battery only. So, we have 2 problems here:

- The default installation of the tlp package from the hardware repo in Leap
15.5 (tlp-1.6.1) blocks the usage of the wifi when the system is battery
powered only. This didn't happen in Leap 15.4 (I can't remember if I was using
the default tlp-1.4.0 or the package from the hardware repo...). I guess the
package from the 15.5 main repo (tlp-1.5.0) should not have this issue, but
after a week with continuous problems to be able to work with my laptop, this
is something I don't want to test right now..

- The NetworkManager floods the system bus in that case, leaving the system in
an unusable state.
