There are several issues to make acpi_video to work in vaio. 1. The LFP's adr is 0x400 instead of 0x110. 2. Lack of _BCL and _BCM method for the LFP output. I think we can write the methods based on the driver sonypi. Hope some guru can help. I paste the related asl code here for the reference. Device (LFP) { Name (_ADR, 0x0400) Method (_DCS, 0, NotSerialized) { Return (GDCS (0x08)) } Method (_DGS, 0, NotSerialized) { Store (GDGS (0x08), Local0) Store (" LFP _DGS return value ", Debug) Store (Local0, Debug) Return (Local0) } Method (_DSS, 1, NotSerialized) { GDSS (Arg0, 0x08) } } -jun
