Public bug reported:
Ubuntu doesn't detect a battery. At upstream kernel 5.4, the battery got
detected but never went under 100%. If the laptop was booted plugged in
to the adapter, a lightning symbol was displayed next to the battery,
but when disconnected from the charger, I won't disappear. Apparently
Ubuntu has no idea how to read out these values from the battery.
Several solutions found on the web were applied without a change of
behavior.
My system is dual-booted with Windows 10. The battery status is
correctly shown in Windows.
Secure boot is disabled.
