HP Recommended
Product: an000na
Operating System: Linux

In ACPI, the DSW method is documented as requiring 3 paramters, but on this laptop, with the latest BIOS, the ACPI appears to expect only 1 parameter.  This causes problems with the linux kernel ACPI implementation. See http://www.uefi.org/sites/default/files/resources/ACPI_5_1release.pdf

 

The full problem is logged here: https://bugzilla.kernel.org/show_bug.cgi?id=191511

 

Could a HP engineer provide feedback?  What does windows do?  What is the expected behaviour? Is it possible to get a new BIOS to fix this?

 

Another HP model is also listed in the bug report with the same behaviour.

 

Thanks
