dmesg

After a BIOS update, the laptop stopped charging after the OS starts (well, it charges at "zero rate", the percentage drops with time). It can only charge when shut down.

Battery 0: Charging, 67%, charging at zero rate - will never fully charge.

The last firmware with charging working was 01.01.12 (but it has its own set of issues)
Tried 01.02.01, 01.03.01, 01.04.01, 01.05.01 and 01.06.00 - "charging at zero rate".

What the issue could be?

Using an original HP USB Type-C charger (45W), blacklisting ucsi_acpi makes no difference, tried several acpi_osi settings, power button EC reset trick did not work.

Linux cannot possibly prevent your laptop from charging.

Call HP and ask questions.

are you sure that it is not charging at all? When AC is connected, it is well possible that the battery doesn't report a charging rate. Is the discharge rate reported (ac plugged off)?
