I've also seen that windows vista document... perhaps it's a requirement to pass vista certification to have the _BCQ method. In addition when I compile the dsdt with iasl it complains about _BCQ as unknown............ Microsoft decided to change that name and hp followed them? Yesterday I've seen that there is a new bios for my machine, version F0A. Does anyone experimented with it? I will try it on the weekend... For now I'll try to change the DSDT file, I use the patch to replace DSDT on linux and I'll report if it works. Regarding the lid switch, is there something I could try?

I can ACK that my HP had a similar typo / feature with its intel based video: 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller (rev 03) The _BQC is absent, but a strange _BCQ is there - which looks to give the correct functionality. The ONLY place I can find any reference to _BCQ is in a couple of Windows Vista design documents about making display brightness work with Vista. Thank you Microsoft, for that typo - presuming thats what it is! Peter Clifton
