Looks like it's still the same problem, you were on 9-stable then too. When did it used to work? On either normal or verbose boot messages, are there any ACPI errors logged? This smells a bit like some of the Embedded Controller issues that were coming up late 2010, most resolved by some patches by avg@. Someone then worked around some EC issue using debug.acpi.ec.polled mode rather than relying on notifications, I vaguely recall. You said then you run only one battery, so hw.acpi.battery.units is also still wrong? > > Are you > > running the latest current?

If there's any indication of ACPI errors on boot (or later) this would be worthy of a PR, especially as you're not alone in this, on HP gear. I suppose you've checked HP for any more recent BIOS &/or EC updates? cheers, Ian
