Hello, Here is the output of dmidecode. I tried "acpi_osi=!Linux" and still got the same message: ACPI: System BIOS is requesting _OSI(Linux) ACPI: Please test with "acpi_osi=!Linux" Please send dmidecode to linux-acpi@xxxxxxxxxxxxxxx in addition, there was: ACPI: Disabled _OSI(Linux) Cheers, Anne-Simone
