UPDATE: after committing some further research, I discovered other Linux
distro's also suffer from this bug. Turns out HP's BIOS is locked and
users are unable to let it report battery statuses to non-Windows
operating systems.
A possible solution is using the distro without the battery indicator,
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. App
